向Pandas describe()方法添加范围

import pandas as pd

# 创建一个示例数据集
data = {'A': [1, 2, 3, 4, 5],
        'B': [10, 20, 30, 40, 50],
        'C': [100, 200, 300, 400, 500]}
df = pd.DataFrame(data)

# 使用describe()方法计算所有数值列的统计信息
print(df.describe())

# 使用include参数指定只计算列A和列B的统计信息
print(df.describe(include=['int64']))

# 使用exclude参数排除列C的统计信息
print(df.describe(exclude=['int64']))
