This dataset includes data that is provided in the Udemy course "Data Analysis with Pandas and Python" by Boris Paskhaver.

Dataset

This dataset was created by Đức Phát Trương

Contents

This dataset was created in 2025 by the CATReloaded team in the Data Science Circle at Mansoura University, Faculty of Engineering, Egypt.

The dataset was originally prepared as the supporting material for a pandas practice notebook. That notebook was designed as a practical task after Corey Schafer’s YouTube pandas course

The goal was to create a comprehensive pandas challenge that includes almost every skill you might need when working with pandas. The idea is that you can save the code and revisit it later whenever you need a reference.

I believe this task could be useful for:

• Anyone just starting with pandas

• Learners who want a structured challenge to test and refresh their skills

• People looking for a practice task they can build on, enhance, or adapt

📌 The full task is available in the pinned notebook here:

💡 Notes:

• The task may contain non-beginner-friendly questions, so don’t worry if they take some time.

• I plan to provide solutions/answers when I have free time to write them down.

• If anyone from the community shares model answers, I’ll be very grateful. I will gladly give credit and mention those contributions so others can benefit from them too.

• You are welcome to design new tasks or variations using this dataset or notebook, as long as credit is kept to the CATReloaded team.

Go to hf and search for flytech/python-codes-25k and download parquet file and upload the dataset on kaggle and call it by pandas

About

This dataset contains 10,703,690 records of running training during 2019 and 2020, from 36,412 athletes from around the world. The records were obtained through web scraping of a large social network for athletes on the internet.

The data with the athletes' activities are contained in dataframe objects (tabular data) and saved in the Parquet file format using the Pandas library, part of the Python ecosystem for data science. Each Pandas dataframe contains the following data (as different columns) for each athlete (as different rows), the first word identifies the name of the column in the dataframe: - datetime: date of the running activity; - athlete: a computer-generated ID for the athlete (integer); - distance: distance of running (floating-point number, in kilometers); - duration: duration of running (floating-point number, in minutes); - gender: gender (string 'M' of 'F'); - age_group: age interval (one of the strings '18 - 34', '35 - 54', or '55 +'); - country: country of origin of the athlete (string); - major: marathon(s) and year(s) the athlete ran (comma-separated list of strings).

For convenience, we created files with the athletes' activities data sampled at different frequencies: day 'd', week 'w', month 'm', and quarter 'q' (i.e., there are files with the distance and duration of running accumulated at each day, week, month, and quarter) for each year, 2019 and 2020. Accordingly, the files are named 'run_ww_yyyy_f.parquet', where 'yyyy' is '2019' or '2020' and 'f' is 'd', 'w', 'm' or 'q' (without quotes). The dataset also contains data with different government’s stringency indexes for the COVID-19 pandemic. These data are saved as text files and were obtained from https://ourworldindata.org/covid-stringency-index.

Acknowlegement

Background

I recently finished the offered courses in Python and Pandas and wanted to practice sorting, creating dataframes, and grouping. I decided to use the hate crime data that is offered by the FBI. To practice, I preemptively separated the full csv file for each territory and state for ease of use by anyone that wants to access their states data right away. Also it provided good practice for coding.

Content

These datasets contain the date of the crime, what kind of crime it was, the offenders race, the victim's race, victim counts (if the victim was a minor or adult), what state and city the crime occurred in, and so on.

Also included is the methodology file so that you can see more context of the data itself and how it was collected.

Acknowledgements

I thought this would be a totally new dataset that has yet been uploaded to kaggle, but I did notice another dataset here, but that hasn't been updated in 2 years. But, I would like to thank that author since it did help me structure how to actually write this out😃 .

Further credit to the FBI for collecting this data which can be found here.

And of course thanks to kaggle for the free courses.

Inspiration

You can use this for several questions to track what years (or decade) had the highest concentration of hate crimes. Also, you can use the full csv file to organize by region for a similar question. But if you want to concentrate on your state, then that is also doable, just download the appropriate table. You can then find what areas in your state had the most hate crimes.

You can also figure out what's the most common hate crime victim over a specific timeframe.

Code I used

(Any feedback is appreciated!) ```

import relevant packages

import pandas as pd

load dataset

hate_crime = pd.read_csv(filepath)

list of states

states = ['AL','AK','AZ', 'AR','CA','CO','CT','DC','DE','FL','FS','GA','GM','HI','IA','ID', 'IL','IN','KS','KY','LA','MD','ME','MI','MN','MO','MS','MT','NB','NC','ND','NH', 'NJ','NM','NV','NY','OH','OK','OR','PA','RI','SC','SC','SD','TN','TX','UT','VA', 'VT','WA','WI','WV','WY']

create DataFrames of just other States

def create_DataFrame(State_Abbr): ''' Parameters ---------- State_Abbr : TYPE == STR USER ENTERS STATE ABBREVIATION

Returns
-------
DATAFRAME OF HATE CRIMES IN THAT STATE

'''
#overall this step is unnecessary because I'm not making an executable or anything
if type(State_Abbr) != str or len(State_Abbr) != 2 or State_Abbr not in states:
  print('Please Enter the State Abbreviation for the desired state')
else: #here's the useful bits ^_^
  hate_df = pd.DataFrame(hate_crime.loc[hate_crime.STATE_ABBR == State_Abbr])
  return hate_df

def create_csv(state_lst): ''' Parameters ---------- def create_csv[state_lst] : Input state list to create seperate csv files for each state.

Returns
-------
A csv of hate crimes within individual states
'''
for state in state_lst:
  df = create_DataFrame(state)
  df.to_csv('Hate Crimes in {} 1991-2020.csv'.format(state))
return

Dataset Description

Musical Scale Dataset: 1900+ Chroma Tensors Labeled by Scale

This dataset contains 1900+ unique synthetic musical audio samples generated from melodies in each of the 24 Western scales (12 major and 12 minor). Each sample has been converted into a chroma tensor, a 12-dimensional pitch class representation commonly used in music information retrieval (MIR) and deep learning tasks.

What’s Inside

• chroma_tensor: A JSON-safe formatted of a PyTorch tensor with shape [1, 12, T], where:
  • 12 = the 12 pitch classes (C, C#, D, ... B)
  • T = time steps
• scale_index: An integer label from 0–23 identifying the scale the sample belongs to

Use Cases

This dataset is ideal for: - Training deep learning models (CNNs, MLPs) to classify musical scales - Exploring pitch-class distributions in Western tonal music - Prototyping models for music key detection, chord prediction, or tonal analysis - Teaching or demonstrating chromagram-based ML workflows

Labels

Quick Load Example (PyTorch)

Chroma tensors are of shape [1, 12, T], where: - 1 is the channel dimension (for CNN input) - 12 represents the 12 pitch classes (C through B) - T is the number of time frames

import torch
import pandas as pd
from tqdm import tqdm

df = pd.read_csv("/content/scale_dataset.csv")

# Reconstruct chroma tensors
X = [torch.tensor(eval(row)).reshape(1, 12, -1) for row in tqdm(df['chroma_tensor'])]
y = df['scale_index'].tolist()

Alternatively, you could directly load the chroma tensors and target scale indices using the .pt file.

import torch
import pandas as pd

data = torch.load("chroma_tensors.pt")
X_pt = data['X'] # list of [1, 12, 302] tensors
y_pt = data['y'] # list of scale indices

How It Was Built

• Notes generated from random melodies using music21
• MIDI converted to WAV via FluidSynth
• Chromagrams extracted with librosa.feature.chroma_stft
• Tensors flattened and saved alongside scale index labels

File Format

Notes

• Data is synthetic but musically valid and well-balanced
• Each of the 24 scales appears 300 times
• All tensors have fixed length (T) for easy batching

The dataset has one training dataset, one testing (unseen) dataset, which is unlabeled, and a clickstream dataset, all interconnected through a common identifier known as "SESSION_ID." This identifier allows us to link user actions across the datasets. A session involves client online banking activities like signing in, updating passwords, viewing products, or adding items to the cart.

Majority of fraud cases add new shipping address, or change password. you can do visualization to get more insights about the nature of frauds.

I also added 2 datasets named "train/test_dataset_combined" which are the merged version of the train and test datasets based on the "SESSION_ID" column. For more information, please refer to this link: https://www.kaggle.com/code/mohammadbolandraftar/combine-datasets-in-pandas

In addition, I added the cleaned dataset after doing EDA. For more information about the EDA process, please refer to this link: https://www.kaggle.com/code/mohammadbolandraftar/a-deep-dive-into-fraud-detection-through-eda

Subtitle: 3-Year Weekly Multi-Channel FMCG Marketing Mix Panel for India Grain: Week-ending Saturday × Geography × Brand × SKU Span: 156 weeks (2 Jul 2022 – 27 Jun 2025) Scope: 8 Indian geographies • 3 brands × 3 SKUs each (9 SKUs) • Full marketing, trade, price, distribution & macro controls • AI creative quality scores for digital banners.

This dataset is synthetic but behaviorally realistic, generated to help analysts experiment with Marketing Mix Modeling (MMM), media effectiveness, price/promo analytics, distribution effects, and hierarchical causal inference without using proprietary commercial data.

Why This Dataset?

Real MMM training data is rarely public due to confidentiality. This synthetic panel:

• Mirrors common FMCG (CPG) category dynamics in India (festive spikes, monsoon effects, geo scale differences).
• Includes paid media channels (TV, YouTube, Facebook, Instagram, Print, Radio).
• Captures promotions & trade levers (feature, display, temporary price reduction, trade spend).
• Provides distribution & availability metrics (Weighted Distribution, Numeric Distribution, TDP, NOS).
• Includes pricing (MRP, Net Price under TPR).
• Adds macro signals (CPI, GDP, Festival Index, Rainfall Index) aligned to India’s seasonality.
• Introduces AI Content Scores (Facebook & Instagram banner creative quality) — letting you explore creative × media interaction models.
• Delivered at a granular panel (Geo × Brand × SKU) suitable for pooled, hierarchical, or Bayesian MMM workflows.

Example: log-transform sales value, normalize media, build price index.

import numpy as np

m = geo_brand.copy()
m["log_sales_val"] = np.log1p(m["Sales_Value"])
m["price_index"] = m["Net_Price"] / m.groupby(["Geo","Brand"])["Net_Price"].transform("mean")

Calendar Notes

• Week variable = week-ending Saturday (Pandas freq W-SAT).
• First week: 2022-07-02; last week: 2025-06-27 (depending on 156-week span anchor).

• To derive a week-start (Sunday) date:

  df["Week_Start"] = df["Week"] - pd.Timedelta(days=6)
