So, I'm working on a script in Python 3, and I need something like this

control_input=input(prompt_029)
if only string_029 and int in control_input:
    #do something
else:
    #do something else

Basically, I am asking for code that would have condition like this:

if control_input == "[EXACT_string_here] [ANY_integer_here]"

How would the code look like in Python 3?

Use regular expressions. –  millimoose Mar 24 '13 at 16:35

What you want is to do a regular expression match. Take a look at the re module. 

>>> import re
>>> control_input="prompt_029"
>>> if re.match('^prompt_[0-9]+$',control_input):
...     print("Matches Format")
... else:
...     print("Doesn't Match Format")
... 
Matches Format

The regular expression ^prompt_[0-9]+$ matches the following:

^        # The start of the string 
prompt_  # The literal string 'prompt_'
[0-9]+   # One or more digit 
$        # The end of the string

If the number must contain exactly three digits then you could use ^prompt_[0-9]{3}$ or for a maximum of three then try ^prompt_[0-9]{1,3}$.

Without regular expression

>>> myvar = raw_input("input: ")
input: string 1
>>> myvar
'string 1'
>>> string, integer = myvar.strip().split()
>>> "[EXACT_string_here] [ANY_integer_here]" == "{} {}".format(string, integer)
True

This doesn't really do what the OP asked for - the integer part in the input is variable, not constantly 1, and there's no straightforward way to modify your code to allow for that. –  millimoose Mar 24 '13 at 18:53
