Python – Convert String Truth values to Boolean
• Last Updated : 02 Sep, 2020

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 lists``test_list ``=` `[``"True"``, ``"False"``, ``"True"``, ``"True"``, ``"False"``]`` ` `# printing string``print``(``"The original list : "` `+` `str``(test_list))`` ` `# using list comprehension to check "True" string``res ``=` `[ele ``=``=` `"True"` `for` `ele ``in` `test_list]`` ` `# printing results ``print``(``"The converted Boolean values : "` `+` `str``(res))`
Output
```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 lists``test_list ``=` `[``"True"``, ``"False"``, ``"True"``, ``"True"``, ``"False"``]`` ` `# printing string``print``(``"The original list : "` `+` `str``(test_list))`` ` `# using map() to extend and lambda to check "True" string``res ``=` `list``(``map``(``lambda` `ele: ele ``=``=` `"True"``, test_list))`` ` `# printing results ``print``(``"The converted Boolean values : "` `+` `str``(res))`
Output
```The original list : ['True', 'False', 'True', 'True', 'False']
The converted Boolean values : [True, False, True, True, False]
```
