Let’s check our first character string my_string1: print(any(c.isalpha()forcinmy_string1))# Check if letters are contained in string# True As you can see, the logical value True has been returned, i.e. our firs
使用 string 模块中的大小写字母常量 string.ascii_letters、数字常量 string.digits，检测密码是否由大写字母、小写字母和数字组成，排除其他字符。使用正则表达式判断import redefcheck_password(password):if len(password) < 8or len(password) > 12:returnFalseifnot re.search("[a-z]", password):returnFalseif...
Python can’t find the all-lowercase string "secret" in the provided text. Humans have a different approach to language than computers do. This is why you’ll often want to disregard capitalization when you check whether a string contains a substring in Python. You can generalize your ...
