Python - Pandas -根据其他列的值替换列中的字符串

import pandas as pd

# 创建一个示例数据集
data = {'Name': ['Alice', 'Bob', 'Charlie', 'David'],
        'Age': [25, 30, 35, 40],
        'Gender': ['Female', 'Male', 'Male', 'Female'],
        'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)

# 根据Gender列的值替换City列中的字符串
replace_dict = {'Female': 'CityA', 'Male': 'CityB'}
df['City'] = df['Gender'].replace(replace_dict)

print(df)
