Question

Define a function in pycharm (isValid) that takes a password as a parameter and returns true if the password is valid or false if the password is invalid.
A valid password must be at least 8 characters long and contains $, _, or @.
Invoke the function and print valid or invalid according to the returned Boolean value. Sample, if (isValid(password) == True):

print(“Valid”)

Or,
result = isValid(password)

If (result): print(“invalid”)

Answer 1

def isValid(p):
    return len(p) >= 8 and ('$' in p or '_' in p or '@' in p)


password = input("Enter password: ")
if isValid(password):
    print("Valid")
else:
    print("Invalid")
