根据列中的重复值拆分DataFrame

import pandas as pd

df = pd.DataFrame({'A': [1, 1, 2, 2, 3, 4], 'B': ['a', 'b', 'c', 'd', 'e', 'f']})

groups = df.groupby('A')

for name, group in groups:
    print("重复值为", name)
    print(group)

groups = df.groupby('A')

for name, group in groups:
    print("重复值为", name)
    print(group)
