Password validator

#### ITERATION DEF ####

def is_password_valid(password):
    length_ok = len(password) > 7
    lowercase_ok = any(c.islower() for c in password)
    uppercase_ok = any(c.isupper() for c in password)
    number_ok = any(c.isdigit() for c in password)
    return sum([length_ok, lowercase_ok, uppercase_ok, number_ok]) == 4


#### ITERATION 1 ####
import string

password = "dfshtj54aA"
lowercase = {x for x in string.ascii_lowercase}
uppercase = {x for x in string.ascii_uppercase}
numbers = {str(x) for x in range(0, 10)}

length_ok = len(password) > 7
lowercase_ok = len(lowercase.intersection(password)) > 0
uppercase_ok = len(uppercase.intersection(password)) > 0
number_ok = len(numbers.intersection(password)) > 0

if length_ok and lowercase_ok and uppercase_ok and number_ok:
    print("Password ok")
else:
    print("Password not ok")

#### ITERATION 2 ####

password = "dfshtj54aA"
lowercase_ok = len(set(string.ascii_lowercase).intersection(password)) > 0
uppercase_ok = len(set(string.ascii_uppercase).intersection(password)) > 0
number_ok = len({str(x) for x in range(0, 10)}.intersection(password)) > 0
result = "Password ok" if (len(password) > 7) + lowercase_ok + uppercase_ok + number_ok == 4 else "Password not ok"
print(result)


#### ITERATION 3 aka VALLIONXD ####

password = "dfshtjd4aDa"
lowercase_ok = any(c.islower() for c in password)
uppercase_ok = any(c.isupper() for c in password)
number_ok = any(c.isdigit() for c in password)
result = "Password ok" if (len(password) > 7) + lowercase_ok + uppercase_ok + number_ok == 4 else "Password not ok"
print(result)


#### ITERATION 4 QUITE UGLY ####

password = "dfshtjdaGa"
pwd = [ord(c) for c in password]
print("Password ok" if (len(pwd) > 7) and (47 < min(pwd) < 58) and (96 < max(pwd) < 123)
        and any(c.isupper() for c in password) else "Password not ok")
