\"\ud83d\udcac\" Question<\/strong>: Given a Boolean value True<\/code> or False<\/code>. How to convert it to a string \"True\"<\/code> or \"False\"<\/code> in Python?<\/p>\n

Note that this tutorial doesn’t concern “concatenating a Boolean to a string”<\/em>. If you want to do this, check out our in-depth article on the Finxter blog<\/a>.<\/p>\n

Simple Bool to String Conversion<\/h2>\n

To convert a given Boolean value to a string in Python, use the str(boolean)<\/a><\/code> function and pass the Boolean value into it. This converts Boolean True<\/code> to string \"True\"<\/code> and Boolean False<\/code> to string \"False\"<\/code>. <\/p>\n

Here’s a minimal example:<\/p>\n

>>> str(True) 'True'\n>>> str(False) 'False'<\/pre>\n
Python Boolean Type is Integer<\/h2>\n
Booleans are represented by integers in Python, i.e., bool<\/code> is a subclass of int<\/code>. Boolean value True<\/code> is represented with integer 1<\/code>. And Boolean value False<\/code> is represented with integer 0<\/code>. <\/p>\n
Here’s a minimal example:<\/p>\n
>>> True == 1\nTrue\n>>> False == 0\nTrue<\/pre>\n
Convert True to ‘1’ and False to ‘0’<\/h2>\n
To convert a Boolean value to a string '1'<\/code> or '0'<\/code>, use the expression str(int(boolean))<\/code>. For instance, str(int(True))<\/code> returns '1'<\/code> and str(int(False))<\/code> returns '0'<\/code>. This is because of Python’s use of integers to represent Boolean values. <\/p>\n
Here’s a minimal example:<\/p>\n
>>> str(int(True)) '1'\n>>> str(int(False)) '0'<\/pre>\n
Convert List of Boolean to List of Strings<\/h2>\n
To convert a Boolean to a string list, use the list comprehension<\/a> expression [str(x) for x in my_bools]<\/code> assuming the Boolean list is stored in variable my_bools<\/code>. This converts each Boolean x<\/code> to a string using the built-in str()<\/code> function and repeats it for all x<\/code> in the Boolean list<\/a>.<\/p>\n
Here’s a simple example:<\/p>\n
my_bools = [True, True, False, False, True]\nmy_strings = [str(x) for x in my_bools]\nprint(my_strings)\n# ['True', 'True', 'False', 'False', 'True']\n<\/pre>\n
Convert String Back to Boolean<\/h2>\n
What if you want to convert the string representation 'True'<\/code> and 'False'<\/code> (or: '1'<\/code> and '0'<\/code>) back to the Boolean representation True<\/code> and False<\/code>?<\/p>\n
\"\ud83d\udc49\" Recommended Tutorial<\/strong>: String to Boolean Conversion<\/a><\/p>\n
Here’s the short summary:<\/p>\n
You can convert a string value s<\/code> to a Boolean value using the Python function bool(s)<\/code>. <\/p>\n
For example, bool('True')<\/code> and bool('1')<\/code> return True<\/code>. <\/p>\n
However, bool('False')<\/code> and bool('0')<\/code> return False<\/code> as well which may come unexpected to you. <\/p>\n
\"\ud83d\udca1\" This is because all Python objects are “truthy”, i.e., they have an associated Boolean value. As a rule of thumb: empty values return Boolean True<\/code> and non-empty values return Boolean False<\/code>. So, only bool('')<\/code> on the empty string ''<\/code> returns False<\/code>. All other strings return True<\/code>!<\/p>\n
You can see this in the following example:<\/p>\n
>>> bool('True')\nTrue\n>>> bool('1')\nTrue\n>>> bool('2')\nTrue\n>>> bool('False')\nTrue\n>>> bool('0')\nTrue\n>>> bool('')\nFalse<\/pre>\n
Okay, what to do about it? <\/p>\n
Easy – first pass the string into the eval()<\/a><\/code> function and then pass the result into the bool()<\/code> function. In other words, the expression bool(eval(my_string))<\/code> converts a string to a Boolean mapping 'True'<\/code> and '1'<\/code> to Boolean True<\/code> and 'False'<\/code> and '0'<\/code> to Boolean False<\/code>. <\/p>\n
Finally – this behavior is as expected by many coders just starting out.<\/p>\n
Here’s an example:<\/p>\n
>>> bool(eval('False'))\nFalse\n>>> bool(eval('0'))\nFalse\n>>> bool(eval('True'))\nTrue\n>>> bool(eval('1'))\nTrue<\/pre>\n
