Booleans represent one of two values: True or False. In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. When you compare two values, the expression is evaluated and Python returns the Boolean answer:

It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True, while the expression 0 == 1 is False. Understanding how Python Boolean values behave is important to programming well in Python. In this tutorial, you’ll learn how to:

The expression '/bla/bla/bla' will be treated as true where a Boolean expression is expected (like in an if statement), but the expressions '/bla/bla/bla' is True and '/bla/bla/bla' == True will evaluate to False for the reasons in Ignacio's answer.

Apr 23, 2025 · Enhance your Python programming skills with these exercises focusing on the boolean data type. Practice writing code to check even/odd numbers, logical AND/OR operations, voting eligibility, palindrome checking, email validation, and more.

True and False can also be represented by 1 and 0. Python also supports boolean operators, although they’re a little different than the comparison operators. Remember that or and and return one of their operands, rather than True or False. >>> "Hello" or None. >>> "Hello" and None. >>> b = True >>> a or b or c. >>> a and b and c.

The expression a != 10 evaluates to True and b != 10 evaluates to False, so the overall expression inside the parentheses is False, and the outer not makes it True. The second part of the expression not b == 5 evaluates to True, so the overall expression is True.

Boolean expressions in Python evaluate to either True or False. They are widely used in conditional statements, loops, and logical operations.

Boolean Expressions. Practice reading expressions that evaluate to either True or False, such as a and (b or not c). The programs in this quiz are randomly generated and will be different every time. Bookmark this page and practice a little every day to see your scores improve.

Python Booleans are represented by the keywords True and False. These values are frequently used in conditional statements like if, elif, and else, as well as in logical operations. They are the result of comparisons or logical operations, and are …

6 days ago · It makes decisions based on True/False conditions, like Python’s boolean values (True or False). Let’s explore Python booleans by stepping into Alex’s world! Booleans are like the ON/OFF switches in Alex’s smart home. If the lights are ON, the system sees it as True. If the lights are OFF, the system sees it as False. Example in Python ...
