要使密碼更強大，它需要滿足以下四個規(guī)則：

1. . 密碼必須包含超過8個字符，且不超過16個字符。“

提示：查找密碼字符串的長度，您應(yīng)該使用len（）方法。

1. 密碼必須包含至少一個數(shù)字、一個大寫字母和一個小寫字母。
2. 密碼必須包含多個非字母數(shù)字字符。

第一種方式是使用函數(shù)

1. if len(a) > 16 or len(a) < 8:
       print(a + "is not of valid length " + str(len(a)))
       isOk = 0
   else:
       print(a + "is of valid length " + str(len(a)))
   print("Check rule 2")
   # Set the function
   lowercases = 0
   uppercases = 0
   digits = 0
   alpha = 0
   # Find, detect output upper and lower case alphanumeric
   for char in a:
       if char.islower():
           lowercases += 1
       elif char.isupper():
           uppercases += 1
       elif char.isdigit():
           digits += 1
   print("Number of lowercase is: " + str(lowercases))
   print("Number of uppercase is: " + str(uppercases))
   print("Number of digit is: " + str(digits))
   if lowercases == 0 or uppercases == 0 or digits == 0:
       print(a + " does not contain enough of each type of character")
       isOk = 0
   else:
       print(a + " contain enough of each type of character")
   print("check rule 3")
   # Detecting special characters
   if alpha != 0:
       print(a + " contain non-alpha-numeric")
   else:
       print(a + " does not contain non-alphanumeric")
       isOk = 0
   print("Check for all the rules")
   if isOk:
       print("Overall " + a + " isvalid")

2. def password_check(passwd):
       SpecialSym = ['$', '@', '#', '%', '@', '!', '&', '=', '+', '_', '-', '$', '/', ]
       val = True
   # check the length
       if len(passwd) < 8:
           print('length should be at > 8')
           val = False
       else:
           print('length is than 8 ')
   
       if len(passwd) > 16:
           print('length should be not be least than 16')
           val = False
       else:
           print('length is least than 16')
   # check the number
       if not any(char.isdigit() for char in passwd):
           print('Password should have at least one numeral')
           val = False
       else:
           print('password have least one numeral')
   
   # check the uppercase
       if not any(char.isupper() for char in passwd):
           print('Password should have at least one uppercase letter')
           val = False
       else:
           print('Password have at least one uppercase letter')
   # check the lowercase
       if not any(char.islower() for char in passwd):
           print('Password should have at least one lowercase letter')
           val = False
       else:
           print('Password have least one lowercase letter')
   # check the Special characters
       if not any(char in SpecialSym for char in passwd):
           print('Password should have at least one of the symbols $@#')
           val = False
       else:
           print('Password have least one of the symbols $@#')
       if val:
           return val
   
   
   def main():
   
       if password_check(password):
   
           print('Password is valid')
       else:
           print("Invalid Password !!")
   
   
   # Driver Code
   if __name__ == '__main__':
       password = input('Enter your password: ')
       main()
   

到了這里，關(guān)于Python檢測密碼是否符合要求，大小寫字母數(shù)字長度等密碼必須包含超過8個字符，且不超過16個字符。密碼必須包含至少一個數(shù)字、一個大寫字母和一個小寫字母。密碼必須包含多個非字母數(shù)字字符。的文章就介紹完了。如果您還想了解更多內(nèi)容，請在右上角搜索TOY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
