Variable not defined in password checker - DAS - Aug-27-2017

I have used the coding below to create a password strength checker but keep getting the upperCase variable not being recognised when I run the program. Any ideas?

[Traceback (most recent call last):
line 33, in <module>
passwordStrength = upperCase + lowerCase + digitCase
NameError: name 'upperCase' is not defined
>>>

Coding
#Test for length of password entered, check length and if outside boundaries
#say password has failed and why

incorrectPass = False

while not incorrectPass:
password = (input("Please enter a password between 6 and 12 characters"))
length = len(password)
if len (password) <6 or len(password)>12:
print ("Password needs to be between 6 and 12 characters, Password entered is only", length, "characters long")
else:
#setflag for strength test
lowerCase = 0
upperCase= 0
digitCase= 0

for ch in password:

if ch.islower():
lowerCase = 1
if ch.isupper():
upperCase= 1
if ch.isdigit():
digitCase= 1

#Strength ouput
passwordStrength = upperCase + lowerCase + digitCase
if passwordStrength ==1:
print ("This is a weak password")
elif passwordStrength ==2:
print ("This is a medium password")
if passwordStrength ==3:
print ("This is a strong password")
incorrectPass = True

Please use proper indentation and formatting. I had to indent your code and it works just fine.

incorrectPass = False

while not incorrectPass:
	password = (input("Please enter a password between 6 and 12 characters"))
	length = len(password) 
	if len (password) <6 or len(password)>12:
		print ("Password needs to be between 6 and 12 characters, Password entered is only", length, "characters long")
	else:
		#setflag for strength test 
		lowerCase = 0
		upperCase= 0
		digitCase= 0



		for ch in password:

			if ch.islower():
				lowerCase = 1
			if ch.isupper():
				upperCase= 1
			if ch.isdigit():
				digitCase= 1

		#Strength ouput
		passwordStrength = upperCase + lowerCase + digitCase
		if passwordStrength ==1:
			print ("This is a weak password")
		elif passwordStrength ==2:
			print ("This is a medium password")
		if passwordStrength ==3:
			print ("This is a strong password")
			incorrectPass = True

Thank you for such a prompt reply
The code works as long as you put the password between 6 and 12 words but when you put
a password of say 3 characters the while loop does not work as it goes straight to the error message.

If the error message is anything other than print ("Password needs to be between 6 and 12 characters, Password entered is only", length, "characters long"), you would need to share it.

And check that the indentation that hbknjr used matches the indentation you are using. If the indentation is off, it could be causing that error.
