如何根据两个参数(使用带有'and‘运算符的lambda函数)计算pandas数据帧中的实例数？

import pandas as pd

df = pd.DataFrame({'A': [1, 2, 3, 4, 5],
                   'B': [True, False, True, False, True],
                   'C': ['apple', 'banana', 'apple', 'banana', 'apple']})

count = len(df[(df['A'] > 2) & (df['B'] == True)])

print(count)

import pandas as pd

df = pd.DataFrame({'A': [1, 2, 3, 4, 5],
                   'B': [True, False, True, False, True],
                   'C': ['apple', 'banana', 'apple', 'banana', 'apple']})

count = len(df[(df['A'] > 2) & (df['B'] == True)])

print(count)
