Python Tutorial: Analyzing WC2026 Match Data with pandas – A Beginner's Guide to Sports Analytics

Learn how to load, clean, and analyze World Cup 2026 match data using Python's most powerful data tool.


Introduction

Sports analytics has exploded in recent years. From predicting match outcomes to identifying underrated players, data-driven insights are transforming how teams compete. But where do you start?

In this tutorial, you'll learn to:

  • ✅ Load and explore real sports data with pandas
  • ✅ Clean messy datasets (handling missing values, inconsistent formats)
  • ✅ Calculate meaningful statistics (possession %, win rates, goal efficiency)
  • ✅ Visualize trends with matplotlib
  • ✅ Build a foundation for advanced analytics projects

We'll use publicly available World Cup-style data (similar to what we'll see in WC2026) and build practical, production-ready code.


Part 1: Setting Up Your Environment

First, install the required libraries:

pip install pandas matplotlib numpy requests

These libraries are the holy trinity of Python analytics:

  • pandas: Data manipulation and analysis (the MVP)
  • matplotlib: Creating charts and visualizations
  • numpy: Numerical computing
  • requests: Fetching data from APIs

Part 2: Loading and Exploring Your First Dataset

Let's start with a practical example. We'll create a sample dataset simulating WC2026 match data, then perform real analysis:

import pandas as pd
import numpy as np
from datetime import datetime, timedelta
import matplotlib.pyplot as plt

# Create a realistic WC2026 match dataset
np.random.seed(42)

matches_data = {
    'match_id': range(1001, 1033),
    'date': pd.date_range('2026-06-01', periods=32, freq='D'),
    'home_team': ['Argentina', 'France', 'Brazil', 'England', 'Spain', 'Germany', 
                  'Netherlands', 'Portugal', 'Belgium', 'Uruguay', 'Italy', 'Denmark',
                  'Croatia', 'Poland', 'Mexico', 'Japan', 'Argentina', 'France', 
                  'Brazil', 'England', 'Spain', 'Germany', 'Netherlands', 'Portugal',
                  'Belgium', 'Uruguay', 'Italy', 'Denmark', 'Croatia', 'Poland', 'Mexico', 'Japan'],
    'away_team': ['Mexico', 'Australia', 'Serbia', 'Iran', 'Costa Rica', 'Japan',
                  'Senegal', 'Uruguay', 'Canada', 'Peru', 'Albania', 'Tunisia',
                  'Morocco', 'Saudi Arabia', 'Poland', 'Spain', 'France', 'Germany',
                  'England', 'Netherlands', 'Brazil', 'Portugal', 'Belgium', 'Italy',
                  'Denmark', 'Croatia', 'Hungary', 'USA', 'Wales', 'Ecuador', 'South Korea', 'Australia'],
    'home_goals': np.random.randint(0, 6, 32),
    'away_goals': np.random.randint(0, 6, 32),
    'home_possession': np.random.uniform(35, 75, 32),
    'away_possession': None,  # We'll calculate this
    'home_shots': np.random.randint(5, 25, 32),
    'away_shots': np.random.randint(5, 25, 32),
    'home_shots_on_target': np.random.randint(2, 15, 32),
    'away_shots_on_target': np.random.randint(2, 15, 32),
}

# Create DataFrame
df = pd.DataFrame(matches_data)

# Calculate away possession (must sum to 100)
df['away_possession'] = 100 - df['home_possession']

# Display first 5 rows
print("First 5 matches of WC2026 Group Stage:")
print(df.head())
print(f"\nDataset shape: {df.shape} (32 matches, 11 statistics)")

Output:

Part 3: Data Cleaning & Feature Engineering

Real data is messy. Let's clean our dataset and create useful new metrics:

# Check for missing values
print("Missing values per column:")
print(df.isnull().sum())

# Remove any completely empty rows
df = df.dropna(how='all')

# Data type verification
print("\nData types:")
print(df.dtypes)

# ====== FEATURE ENGINEERING ======

# 1. Determine match result (1 = home win, 0 = draw, -1 = away win)
df['result'] = np.where(df['home_goals'] > df['away_goals'], 1,
                        np.where(df['home_goals'] < df['away_goals'], -1, 0))

# 2. Total goals per match
df['total_goals'] = df['home_goals'] + df['away_goals']

# 3. Goal difference
df['goal_difference'] = df['home_goals'] - df['away_goals']

# 4. Shot conversion rate (goals / shots on target)
df['home_conversion_rate'] = df['home_goals'] / df['home_shots_on_target']
df['away_conversion_rate'] = df['away_goals'] / df['away_shots_on_target']

# Handle division by zero (replace inf with 0)
df['home_conversion_rate'].replace([np.inf, -np.inf], 0, inplace=True)
df['away_conversion_rate'].replace([np.inf, -np.inf], 0, inplace=True)

# 5. Efficiency metric: shots on target / total shots
df['home_efficiency'] = (df['home_shots_on_target'] / df['home_shots'] * 100).round(2)
df['away_efficiency'] = (df['away_shots_on_target'] / df['away_shots'] * 100).round(2)

print("\nEnhanced dataset with new metrics:")
print(df[['match_id', 'home_team', 'away_team', 'home_goals', 'away_goals', 
          'result', 'total_goals', 'home_conversion_rate', 'home_efficiency']].head(10))

Part 4: Statistical Analysis

Now let's extract meaningful insights from the data:

# ====== AGGREGATE STATISTICS ======

print("="*60)
print("WC2026 GROUP STAGE ANALYSIS")
print("="*60)

# 1. Match statistics
print(f"\nTotal matches: {len(df)}")
print(f"Average goals per match: {df['total_goals'].mean():.2f}")
print(f"Average possession (home teams): {df['home_possession'].mean():.2f}%")

# 2. Result distribution
result_counts = df['result'].value_counts().sort_index(ascending=False)
print(f"\nMatch results distribution:")
print(f"  Home wins: {result_counts[1]} ({result_counts[1]/len(df)*100:.1f}%)")
print(f"  Draws: {result_counts[0]} ({result_counts[0]/len(df)*100:.1f}%)")
print(f"  Away wins: {result_counts[-1]} ({result_counts[-1]/len(df)*100:.1f}%)")

# 3. Team performance analysis
team_stats = []
for team in set(list(df['home_team']) + list(df['away_team'])):
    home_matches = df[df['home_team'] == team]
    away_matches = df[df['away_team'] == team]

    home_wins = (home_matches['result'] == 1).sum()
    away_wins = (away_matches['result'] == -1).sum()
    total_wins = home_wins + away_wins

    home_goals = home_matches['home_goals'].sum()
    away_goals = away_matches['away_goals'].sum()
    total_goals = home_goals + away_goals

    home_conceded = home_matches['away_goals'].sum()
    away_conceded = away_matches['home_goals'].sum()
    total_conceded = home_conceded + away_conceded

    total_matches = len(home_matches) + len(away_matches)

    if total_matches > 0:
        team_stats.append({
            'Team': team,
            'Matches': total_matches,
            'Wins': total_wins,
            'Goals': total_goals,
            'Conceded': total_conceded,
            'GD': total_goals - total_conceded,
            'Win%': round(total_wins / total_matches * 100, 1)
        })

# Create team rankings
team_df = pd.DataFrame(team_stats).sort_values('Wins', ascending=False)
print("\nTop 10 Teams by Wins:")
print(team_df.head(10).to_string(index=False))

# 4. Correlation analysis
print("\n" + "="*60)
print("PERFORMANCE CORRELATIONS")
print("="*60)
correlations = df[['home_possession', 'home_shots_on_target', 
                     'home_efficiency', 'home_goals']].corr()
print(correlations.iloc[-1, :-1])  # Correlation with goals

python
import matplotlib.pyplot as plt
import seaborn as sns

# Set style
sns.set_style("whitegrid")
plt.rcParams['figure.figsize'] = (14, 10)

fig, axes = plt.subplots(2, 2, figsize=(15, 10
