Python – Remove suffix from string list

Last Updated : 17 Dec, 2019

Sometimes, while working with data, we can have a problem in which we need to filter the strings list in such a way that strings ending with specific suffix are removed. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop + remove() + endswith()
The combination of above functions can solve this problem. In this, we remove the elements that end with particular suffix accessed using loop and return the modified list.

# Python3 code to demonstrate working of
# Suffix removal from String list
# using loop + remove() + endswith()
  
# initialize list 
test_list = ['allx', 'lovex', 'gfg', 'xit', 'is', 'bestx']
  
# printing original list 
print("The original list : " + str(test_list))
  
# initialize suffix
suff = 'x'
  
# Suffix removal from String list
# using loop + remove() + endswith()
for word in test_list[:]:
    if word.endswith(suff):
        test_list.remove(word)
  
# printing result
print("List after removal of suffix elements : " + str(test_list))

Output :

The original list : ['allx', 'lovex', 'gfg', 'xit', 'is', 'bestx']
List after removal of suffix elements : ['gfg', 'xit', 'is']

Method #2 : Using list comprehension + endswith()
This is another way in which this task can be performed. In this, we don’t perform removal in place, instead, we recreate the list without the elements that match the suffix.

# Python3 code to demonstrate working of
# Suffix removal from String list
# using list comprehension + endswith()
  
# initialize list 
test_list = ['allx', 'lovex', 'gfg', 'xit', 'is', 'bestx']
  
# printing original list 
print("The original list : " + str(test_list))
  
# initialize suff
suff = 'x'
  
# Suffix removal from String list
# using list comprehension + endswith()
res = [ele for ele in test_list if not ele.endswith(suff)]
  
# printing result
print("List after removal of suffix elements : " + str(res))

Output :

The original list : ['allx', 'lovex', 'gfg', 'xit', 'is', 'bestx']
List after removal of suffix elements : ['gfg', 'xit', 'is']
