如何在python中使用pandas计算日期范围内满足某些条件的天数

import pandas as pd

start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2022-12-31')
date_range = pd.date_range(start=start_date, end=end_date)

df = pd.DataFrame({'date': date_range})

df['is_condition_met'] = df['date'].apply(lambda x: True if x.weekday() < 5 else False)

num_days = df['is_condition_met'].sum()

import pandas as pd

start_date = pd.to_datetime('2022-01-01')
end_date = pd.to_datetime('2022-12-31')
