I have been given the task to remove all non numeric characters including spaces from a either text file or string and then print the new result next to the old characters for example:
Before:
sd67637 8
After:
676378
As i am a beginner i do not know where to start with this task. Please Help
The easiest way is with a regexp
import re
a = 'lkdfhisoe78347834 (())&/&745 '
result = re.sub('[^0-9]','', a)
print result
>>> '78347834745'
