Python Boolean and Conditional Programming: if.. else
The Python if statement. First, we define a variable called door_is_locked and set it to True.Next, you’ll find an if-statement. This is a so-called conditional statement. It is followed by an expression that can evaluate to either True or False.If the expression evaluates to True, the block of code that follows is executed.If it evaluates to False, it is skipped.

Conditional Statements in Python
In the form shown above: <expr> is an expression evaluated in a Boolean context, as discussed in the section on Logical Operators in the Operators and Expressions in Python tutorial. <statement> is a valid Python statement, which must be indented. (You will see why very soon.) If <expr> is true (evaluates to a value that is “truthy”), then <statement> is executed.

Python Booleans - W3Schools
Boolean Values. 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:

Python Conditionals, Booleans, and Comparisons • datagy
Python Logical Operators: Combining Booleans. Another way that we can check the truthy-ness of Python statements is to use logical operators. These operators are represents by and, or, and not. They evaluate against a boolean expression and have different truth tables associated with them. Before diving into the truth tables, let’s take a look at an example of how these work: # Using the and ...

Python If Boolean Logic - CodingBat
Python If Boolean Logic. In Python, use == to compare two things for equality -- works for int values, strings, lists ... anything. Python supports all the standard operators to compare two values: == != < <= > >=. The boolean operators are written out as and or not. Here's an example if-statement:
