Syntax for an If statement using a boolean

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?

RandomBool1 == True # Boolean states True
if # AnyThing:
    RandomBool1 = False # Boolean states False from now on?

You can change the value of a bool all you want. As for an if:

if randombool is True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool is False

but you can also use:

if not randombool:

According to PEP 8, it looks like we should just be using

if RandomBool:

or

if not RandomBool:

I believe is compares memory addresses, and PEP 8 says we shouldn't compare bools with ==:

I think You could also just use

if randombool is True:

elif randombool is False:

I don't think you need to use equal signs unless it's an int or float.

Correct me if I'm wrong
