Variable is not defined error when trying to use my custom function code

[fnafgamer239]

Hi so I recently am transitioning from Snap! to python and im trying to recreate something I did in snap but I am having some problems.

1 2 3 4 5 6 7 8 9

# CONTAINS LETTER BLOCK def contains_letter(string1,letter):     for i in len(string1):         if i==letter:             print(True)         else:             print(False)          contains_letter(hello,h)

When I put hello and h in it just says undefined variable in the problems section. Also im pretty sure some of that code might not work as well as I was trying to find something that would work with what i want it to do.

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

Please use bbtags when posting code.

hello is a string and needs to be 'hello' as well as the letter 'h'

Example:

1 2 3 4 5 6 7

def contains_letter(string, letter):     for letters in string:         if letters == letter:             return True     return False   print(contains_letter('hello', 'h'))

output

Output:
True

oh okay sorry for not using the bb text I was trying to but I couldn't find the shortcut on the text editor thingy. Also thank you I didn't know that the input had to be in quotations for string inputs. I will also be using the return function lol I didnt know that was a thing in here.

Input does not need to be in quotes, str literals need to be in quotes.

'hello' - makes a str
"hello" - makes a str
hello = "hello" - makes a variable named hello and assignes it to reference a str.

There is no reason to write your function in Python. This code

1	print("h" in "hello")

Checks if the str "hello" contains the str "h" and prints True if it does. The "in" operator performs the test.

Example:

1 2 3 4 5 6 7

def contains_letter(string, letter):     for letters in string:         if letters == letter:             return True     return False   print(contains_letter('hello', 'h'))

You can simply that to:

1 2	def contains_letter(string, letter):     return bool(letter in string)
