Pandas嵌入字典到具有列名匹配键的列

import pandas as pd

data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'City': ['New York', 'Los Angeles', 'London']}

df = pd.DataFrame(data)

income = {'Alice': 5000, 'Bob': 6000, 'Charlie': 7000}

df['Income'] = df['Name'].map(income)

import pandas as pd

data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'City': ['New York', 'Los Angeles', 'London']}
df = pd.DataFrame(data)

income = {'Alice': 5000, 'Bob': 6000, 'Charlie': 7000}
df['Income'] = df['Name'].map(income)

print(df)
