How to Change Boolean Values in Python

In Python, or in any other programming language, understanding Boolean data is crucial as it can help us manipulate and control various program flows. This short tutorial will teach you how to manipulate Boolean values in Python.

Understanding Boolean Values in Python

A Boolean value is one of the simplest types in Python. Boolean in Python can have two values – True or False which can be compared to 1 and 0 respectively. We use logically-based conditions in programming to control workflows or set parameters.

Creating and Changing Boolean in Python

To declare a Boolean in Python, you can simply assign either True or False to a variable. For example:

1
isPythonFun = True

To change a Boolean value, you can reassign a new value to the variable. Continuing the previous code:

1
isPythonFun = False

Boolean Operations

Python supports three basic Boolean operations:

  • and: Returns True only when both inputs are True.
  • or: Returns True when at least one input is True.
  • not: Returns the inverse of the input Boolean.

a = True
b = False
 
# prints True because both a and b are not True
print(a and b)
 
# prints True because a is True
print(a or b)
 
# prints False because a is not False
print(not a)

# Declare a Boolean value
isPythonFun = True
 
# Change the Boolean value
isPythonFun = False
 
# Declare two Boolean values
a = True
b = False
 
# Test 'and' logic
print(a and b)  
 
# Test 'or' logic
print(a or b)  
 
# Test 'not' logic
print(not a)  

The Output

False
True
False

Conclusion

As we navigate through different tasks in Python, understanding how Boolean values work becomes crucial for decision-making processes in our code.

This tutorial introduced you to Boolean values in Python, teaching you how to create, change, and operate with them. Please refer to the official Python documentation for more details about Boolean operations.
