Python Python Basics (Retired) Things That Count Exceptions

Cannot get percent_letter.py to work- error text in post

I've gone over this several times, erased my code and retyped it from that in the video, either i'm missing a typo in the same place each time, or it''s just not working for me. Here's my code:

user_string = input("What's your word? ")
user_num = ("What's 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_name)
    print(user_string[ratio])

It asks me for a word, and I input the same as the video, magic. I get the following:

During handling of the above exception, another exception occurred:

    our_num = float(user_num)                                                                                                               
ValueError: could not convert string to float: "What's your number? "

In your code, user_num, on line 2, is a string because you left out the input function name.

ratio = round(len(user_string)*our_name) should be:

ratio = round(len(user_string)*our_num)?

Yeah, it should be. I'm assuming that's just a typo here in the forum instead of in actual code.
