如何获取给定日期之间每天的行数？

from datetime import datetime, timedelta

def count_lines_between_dates(start_date, end_date):
    current_date = start_date
    line_count = 0

    while current_date <= end_date:
        # 在这里替换为您的文件名
        with open("file_{}.txt".format(current_date.strftime("%Y-%m-%d")), "r") as file:
            line_count += len(file.readlines())
        current_date += timedelta(days=1)

    return line_count

start_date = datetime.strptime("2022-01-01", "%Y-%m-%d")
end_date = datetime.strptime("2022-01-31", "%Y-%m-%d")

total_lines = count_lines_between_dates(start_date, end_date)
print("总行数：", total_lines)
