python - Syntax for an If statement using a boolean - Stack Overflow
I just recently joined the python3 HypeTrain. However I just wondered how you can use an if statement onto a boolean. Example: RandomBool = True # and now how can I check this in an if statement? Like the following: if RandomBool == True: # DoYourThing And also, can I just switch the value of a boolean like this?

Using booleans in an if statement in Python - bobbyhadz
# Using booleans in an if statement in Python. Use the is operator to check for a boolean value in an if statement, e.g. if variable is True:. ... The first example checks if the variable stores a True boolean value. You should use the is operator when you need to check if a variable stores a boolean value or None. Use the equality operators (equals == and not equals !=) ...

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: Example. print(10 > 9) print(10 == 9) print(10 < 9)

Python Booleans: Use Truth Values in Your Code
The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True, ... For the same reason you can’t assign to +, it’s impossible to assign to True or False. Only two Python Boolean values exist. A Boolean operator with no inputs always returns the same value. Because of this, True and False are the only two Boolean operators that don’t take inputs.

Python Boolean and Conditional Programming: if.. else
Boolean A boolean is the simplest data type; it’s either True or False. In computer science, booleans are used a lot. This has to do with how computers work internally. Many operations inside a computer come down to a simple “true or false.” It’s important to note, that in Python a Boolean value starts with an upper-case letter: True or ...

Python - if, else, elif conditions (With Examples) - TutorialsTeacher.com
Any Boolean expression evaluating to True or False appears after the if keyword. Use the : symbol and press Enter after the expression to start a block with an increased indent. One or more statements written with the same level of indent will be executed if the Boolean expression evaluates to True. To end the block, decrease the indentation.

If and Comparisons - Computer Science
The if-statement controls if some lines run or not. A "boolean" is a value which is True or False. The if-statement has a boolean-test, a colon, and indented lines of code (similar to "while"): if boolean-test: indented body lines. The if-statement first evaluates the the boolean test, and if it is True, runs the "body" lines once.

Python Concepts/If Statement - Wikiversity
It will compute if a statement is true or false. If it's true, it will execute the code. If it's false, it won't execute the code. Remember that True and False are Booleans in Python. This means that if and other conditional statements will use Boolean math to compute their Boolean state. You should also note the need for a colon (:) at the end of the if statement. This is needed at the end of a control flow statement.

Conditional Statements — Python Like You Mean It
Likewise Python ascribes boolean values to non-boolean objects. For example,the number 0 is associated with False and non-zero numbers are associated with True. The boolean values of built-in objects can be evaluated with the built-in Python command bool:
