Python Python Basics (Retired) Things That Count Exceptions

Invalid Syntax

This is my code:

user_string = input("What's your word? ")
user_num = input("What's your number? ")

  our_num - int(user_num)
  our_num = float(user_num)

if not "." in user_num:
  ratio = round(len(user_string) * our_num)

#When I run it I get the following syntax error message:

File "percent_letter,py", line 9
   if not '.' in user num:

SyntaxError: invalid syntax

If changed the "." to '.' and get the same error. I've also copied and pasted code from other posts and get the same error.

Please help!! :(

If user_num is a string, if '.' not in user_num: and if not '.' in user_num: both work.

There appears to be a typo: "-" where a "=" should be:

  our_num = int(user_num) # <-- replaced - with =
  our_num = float(user_num)
