比较dataframe中的值并使用它计算另一个属性

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

df['C'] = df['A'] > df['B']

df['D'] = df['A'] * df['C']

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

df['C'] = df['A'] > df['B']
df['D'] = df['A'] * df['C']

print(df)

   A   B      C  D
0  1  10  False  0
1  2  20  False  0
2  3  30  False  0
3  4  40  False  0
4  5  50  False  0
