Sometimes, while working with String lists, we can have a problem in which we need to perform the deletion of extra characters that can be termed as unwanted and occur at end of each string. Let’s discuss a way in which this task can be performed.
Method : Using map() + str.strip()
Combination of the above two functionalities can help us achieve this particular task. In this, we employ strip()
, which has the ability to remove the trailing and leading special unwanted characters from string list. The map()
, is used to extend the logic to each element in list.
# Python3 code to demonstrate working of # Remove trailing / leading special characters from strings list # Using map() + str.strip() # initializing list test_list = [ '\rgfg\t\n' , 'is\n' , '\t\tbest\r' ] # printing list print ( "The original list : " + str (test_list)) # Remove trailing / leading special characters from strings list # Using map() + str.strip() res = list ( map ( str .strip, test_list)) # Printing result print ( "List after removal of special characters : " + str (res)) |
The original list : ['\rgfg\t\n', 'is\n', '\t\tbest\r'] List after removal of special characters : ['gfg', 'is', 'best']
