Python | Remove trailing/leading special characters from strings list

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))

Output :

 
The original list : ['\rgfg\t\n', 'is\n', '\t\tbest\r']
List after removal of special characters : ['gfg', 'is', 'best']
