从DataFrame Pandas中随机选择行

df.sample(n=None, frac=None, replace=False, weights=None, random_state=None, axis=None)

import pandas as pd

# 创建一个DataFrame
data = {'Name': ['Alice', 'Bob', 'Charlie', 'David', 'Eve'],
        'Age': [25, 30, 35, 40, 45],
        'City': ['New York', 'London', 'Paris', 'Tokyo', 'Sydney']}
df = pd.DataFrame(data)

# 从DataFrame中随机选择2行
random_rows = df.sample(n=2)

# 输出选择的行
print(random_rows)
