Given a String List, convert the String Truth values to Boolean values.
Input : test_list = [“True”, “False”, “True”, “False”]
Output : [True, False, True, False]
Explanation : String booleans converted to actual Boolean.Input : test_list = [“True”]
Output : [True]
Explanation : String boolean converted to actual Boolean.
Method #1 : Using list comprehension
In this, we check for just the True value, rest values are automatically converted to False boolean.
Python3
# Python3 code to demonstrate working of # Convert String Truth values to Boolean# Using list comprehension # initializing liststest_list = ["True", "False", "True", "True", "False"] # printing stringprint("The original list : " + str(test_list)) # using list comprehension to check "True" stringres = [ele == "True" for ele in test_list] # printing results print("The converted Boolean values : " + str(res)) |
The original list : ['True', 'False', 'True', 'True', 'False'] The converted Boolean values : [True, False, True, True, False]
Method #2 : Using map() + lambda
In this, we apply same approach, just the different way to solve the problem. The map() is used to extend logic of values computed by lambda function.
Python3
# Python3 code to demonstrate working of # Convert String Truth values to Boolean# Using map() + lambda # initializing liststest_list = ["True", "False", "True", "True", "False"] # printing stringprint("The original list : " + str(test_list)) # using map() to extend and lambda to check "True" stringres = list(map(lambda ele: ele == "True", test_list)) # printing results print("The converted Boolean values : " + str(res)) |
The original list : ['True', 'False', 'True', 'True', 'False'] The converted Boolean values : [True, False, True, True, False]
