Python

Script not running

After checking the other questions posted and trying fixes that others had the same issue, I still can't run the script. It simply returns the line in the console.

Here's my code:

user_string = input("Whats your word? ")
user_num = input("Whats your number? ")

try:
  our_num = int(user_num)
except:
  our_num = float(user_num)

if not '.' in user_num:
  print(user_string[our_num])
else:
  ratio = round(len(user_string)*our_num)
  print(user_string[ratio])

I hope I'm not forgetting anything, thanks for the help!

Hey Ryley, your code works correctly. Not sure how you were trying to run it.

If you save your code to a file, such as, exception_test.py. Then you can run code using the Python interpretor:

python exception_test.py

Otherwise, you can also run it interactively in the Python interpretor:

$ python3
Python 3.4.0 (default, Jun 19 2015, 14:20:21) 
[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> user_string = input("Whats your word? ")
Whats your word? RyleyHamill
>>> user_num = input("Whats your number? ")
Whats your number? 0.75
>>> try:
...     our_num = int(user_num)
... except:
...     our_num = float(user_num)
... 
>>> if not '.' in user_num:
...     print(user_string[our_num])
... else:
...     ratio = round(len(user_string) * our_num)
...     print(user_string[ratio])
... 
i

As a code critique, though syntactically equivalent,

if '.' not in user_num:

is preferred over:

if not '.' in user_num:

What challenge is this for?
