Given a Tuple list, remove K character from 1st element of Tuple being String.
Input : test_list = [(“GF$g!”, 5), (“!i$s”, 4), (“best!$”, 10)], K = ‘$’
Output : [(‘GFg!’, 5), (‘!is’, 4), (‘best!’, 10)]
Explanation : First element’s strings K value removed.Input : test_list = [(“GF$g!”, 5), (“best!$”, 10)], K = ‘$’
Output : [(‘GFg!’, 5), (‘best!’, 10)]
Explanation : First element’s strings K value removed.
Method #1 : Using replace() + list comprehenson
In this, we use replace() to perform task of removal of K character and list comprehension to reform tuple.
Python3
# Python3 code to demonstrate working of # Remove K character from first element of Tuple# Using replace() + list comprehenson # initializing listtest_list = [("GF ! g !", 5), ("! i ! s", 4), ("best !!", 10)] # printing original listprint("The original list is : " + str(test_list)) # initializing K K = "!" # replace with empty string removes the desired char.res = [(sub[0].replace(K, ''), sub[1]) for sub in test_list] # printing result print("The filtered tuples : " + str(res)) |
The original list is : [('GF!g!', 5), ('!i!s', 4), ('best!!', 10)]
The filtered tuples : [('GFg', 5), ('is', 4), ('best', 10)]
Method #2 : Using translate() + list comprehension
In this, we perform task of removal using translate(), which needs conversion to ascii using ord(), and replaced with empty character.
Python3
# Python3 code to demonstrate working of # Remove K character from first element of Tuple# Using translate() + list comprehension # initializing listtest_list = [("GF ! g !", 5), ("! i ! s", 4), ("best !!", 10)] # printing original listprint("The original list is : " + str(test_list)) # initializing K K = "!" # translation after conversion to ascii number res = [(sub[0].translate({ord(K): None}), sub[1]) for sub in test_list] # printing result print("The filtered tuples : " + str(res)) |
The original list is : [('GF!g!', 5), ('!i!s', 4), ('best!!', 10)]
The filtered tuples : [('GFg', 5), ('is', 4), ('best', 10)]
