我的代码可以在IDLE中运行，但不能在崇高的文字3中运行（IndentationError）

Question

该代码可以在空闲状态下运行，但是在sublime text3中，有很多IndentationErrors

我检查了“制表符”和“空格”是否正确（制表符之间没有空格） 并且我还更改了sublime text3（“ draw_white_space”：“ all”）中的设置

仍然不起作用

def check():
    symbols = r'''`!@#$%^&*()_+-=/*{}[]\|'";:/?,.<>'''
    chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
    nums = '0123456789'
    password = input('please enter the password\n')
    pass_len = len(password)

    while password.isspace() or pass_len == 0:
        password = input('your password is null or include space, please try again\n')

    if pass_len >= 16:
        len_flag = 3
    elif pass_len > 8:
        len_flag = 2
    else:
        len_flag = 1

    str_flag = 0
    for each in password:
        if each in symbols:
            str_flag += 1
            break

    for each in password:
        if each in chars:
            str_flag += 1
            break   

    for each in password:
        if each in nums:
            str_flag += 1
            break

    if len_flag == 1 or str_flag == 1:
        print('low')
    elif len_flag == 2 or str_flag == 2:
        print('medium')
    else:
        print('high')

谁能告诉我下一次发生的事情以及如何避免。非常感谢
