Python simulates removing whitespace on both sides of a string

Goal:
1. Using the whitespace of the string module
2. Delete left, right, and white space on both sides

The code is as follows:

[email protected] python]# cat rmspace.py

#!/usr/bin/env python#Coding:utf8"""use a string to remove left and right whitespace. """ fromStringImportwhitespace#Delete the left blankdefLrmsps (ASTR): forIinchxrange (len (ASTR)):ifAstr[i] not inchwhitespace:returnAstr[i:]#when all whitespace characters are entered, NULL is returned.    return "'#Delete the blank on the right and start judging from the right of the list. defRrmsps (ASTR): forIinchReversed (xrange (Len (ASTR))):ifAstr[i] not inchwhitespace:returnAstr[:(i+1)]    return "'#Delete left and right sides of white spacedefRmsps (ASTR):returnRrmsps (Lrmsps (ASTR))if __name__=='__main__': Hi='Hello,world. '    Print 'Delete left blank: |%s|'%Lrmsps (HI)Print 'Delete Right blank: |%s|'%Rrmsps (HI)Print 'Delete both sides blank: |%s|'% Rmsps (HI)

2. Run the code and test the effect

[[email protected] python] # python rmspace.py Delete left blank: |hello,world.      | Delete right margin:|    hello,world.| Delete both sides blank:|hello,world.|
