Well, I am assuming that by this you mean converting user input into a
string, and then extracting the numerals (0-9) from it. Next time, please
tell us your version of Python. I'll do my best to help with this. You
might try the following:
the_input = input("Insert string here: ") # change to raw_input in python 2
after = ""
for char in the_input:
try:
char = int(char)
except:
after += char
If other symbols might be in the string ($, @, etc.), then you might use
the_input = input('Insert string here: ') # change to raw_input in python 2
after = ''
not_allowed = '1234567890-=!@#$%^&**()_+,./<>?`~[]{}\\|'
for char in the_input:
if char in not_allowed:
pass
else:
after += char
This method requires more typing, but it works with a wider variety of
characters. Hopefully this helped.
