Question

Write a Python function fun8(k) that gets list of strings k as passwords and returns the valid passwords in list format. Criteria for checking passwords:

1.) At least 1 letter between [a-z]

2.) At least 1 letter between [A-Z]

3.) At least 1 number between [0-9]

4.) At least 1 character from [$#@]

5.) Minimum length of transaction password: 6

6.) Maximum length of transaction password: 12

7.) No spaces

Example:

>>>lst=["ABd1234@1", "a F1#,2w3E*", "2We3345"]

>>>fun8(lst)

[ABd1234@1]

Answer 1

def fun8(lst):
    result = []
    for x in lst:
        hasLower = False
        hasUpper = False
        hasDigit = False
        hasSpecial = False
        hasNoSpace = True
        if(len(x)>=6 and len(x)<=12):
            for i in x:
                if(i.islower()):
                    hasLower = True
                if(i.isupper()):
                    hasUpper = True
                if(i.isdigit()):
                    hasDigit = True
                if i in "$#@":
                    hasSpecial = True
                if(i == ' '):
                    hasNoSpace = False
            if(hasLower and hasUpper and hasDigit and hasSpecial and hasNoSpace):
                result.append(x)
    return result

# Testing
lst=["ABd1234@1", "a F1#,2w3E*", "2We3345"]
print(fun8(lst))

['ABd1234@1']
