替换pandas中以另一列为条件的列的某些值

import pandas as pd
import numpy as np

# 创建一个示例DataFrame
data = {'A': [1, 2, 3, 4, 5],
        'B': [10, 20, 30, 40, 50],
        'C': ['apple', 'banana', 'apple', 'banana', 'apple']}
df = pd.DataFrame(data)

# 使用np.where()函数替换以另一列为条件的列的某些值
df['C'] = np.where(df['A'] > 3, 'orange', df['C'])

print(df)

   A   B       C
0  1  10   apple
1  2  20  banana
2  3  30   apple
3  4  40  orange
