方法1：基础百分比统计

import pandas as pd
import numpy as np
def pass_distribution_basic(passes):
    """
    基础长短传比例统计
    passes: 传球数据列表，每个元素为 {'distance': 距离(米), 'type': 传球类型}
    """
    # 将数据转换为DataFrame
    df = pd.DataFrame(passes)
    # 定义长短传标准（以25米为界）
    short_pass = df[df['distance'] < 25]
    long_pass = df[df['distance'] >= 25]
    # 计算比例
    total = len(df)
    short_ratio = len(short_pass) / total * 100
    long_ratio = len(long_pass) / total * 100
    return {
        'short_pass_count': len(short_pass),
        'long_pass_count': len(long_pass),
        'short_pass_ratio': round(short_ratio, 2),
        'long_pass_ratio': round(long_ratio, 2),
        'total_pass': total
    }
# 示例数据
passes = [
    {'distance': 15, 'type': 'ground'},
    {'distance': 30, 'type': 'air'},
    {'distance': 20, 'type': 'ground'},
    {'distance': 40, 'type': 'air'},
    {'distance': 10, 'type': 'ground'},
]
result = pass_distribution_basic(passes)
print(result)

方法2：按距离分段统计

def pass_distance_distribution(passes, bins=None):
    """
    按距离区间统计传球分布
    """
    df = pd.DataFrame(passes)
    if bins is None:
        bins = [0, 10, 20, 30, 40, 50, float('inf')]
        labels = ['0-10m', '10-20m', '20-30m', '30-40m', '40-50m', '50m+']
    # 创建距离区间
    df['distance_range'] = pd.cut(df['distance'], bins=bins, labels=labels, right=False)
    # 统计各区间数量
    distribution = df['distance_range'].value_counts().sort_index()
    # 计算比例
    total = len(df)
    ratio_distribution = (distribution / total * 100).round(2)
    return pd.DataFrame({
        'count': distribution,
        'percentage': ratio_distribution
    })
# 使用示例
result_df = pass_distance_distribution(passes)
print(result_df)

方法3：可视化展示

import matplotlib.pyplot as plt
import seaborn as sns
def pass_visualization(df):
    """
    传球分布可视化
    """
    fig, axes = plt.subplots(1, 2, figsize=(12, 5))
    # 长短期传球饼图
    short_count = len(df[df['distance'] < 25])

    axes[0].pie([short_count, long_count], 
                labels=['短传', '长传'], 
                autopct='%1.1f%%',
                colors=['#66b3ff', '#ff9999'])
    axes[0].set_title('长短传比例分布')
    # 距离直方图
    df['distance'].hist(ax=axes[1], bins=20, color='skyblue', alpha=0.7)
    axes[1].set_title('传球距离分布')
    axes[1].set_xlabel('传球距离(米)')
    axes[1].set_ylabel('传球次数')
    plt.tight_layout()
    plt.show()
# 生成更多示例数据
np.random.seed(42)
pass_data = []
for _ in range(100):
    distance = np.random.normal(30, 10)
    distance = max(5, min(60, distance))  # 限制范围
    pass_data.append({'distance': distance, 'type': np.random.choice(['ground', 'air'])})
pass_visualization(pd.DataFrame(pass_data))

方法4：完整统计分析类

        type_stats = self.df.groupby('type')['distance'].agg(['count', 'mean', 'std'])
        type_stats['percentage'] = (type_stats['count'] / self.total * 100).round(2)

# 使用示例
analyzer = PassAnalyzer(passes)
print("长短传比例:", analyzer.short_long_ratio())

方法5：分组对比分析

    team1_analyzer = PassAnalyzer(team1_data)
