How can you put a bool in a if else statement in Python?

class Wheels(Car):
    def __init__(self, name, noise, canMakeNoise):
        self.name = name
        self.noise = noise
        self.canMakeNoise = Bool

    def makeNoise(self):
        if canMakeNoise = False:
            Wheels.name + "" + "vroom"
        else: 
            print Wheels.name + "" + "remains silent"

If I run that code, I get this error:

File "python", line 26
    if canMakeNoise = False:
                    ^
SyntaxError: invalid syntax

You can use a ternary if/else, also using str.format will make your concatenation a bit nicer:

print"{} remains silent".format(Wheels.name) if canmakeNoise else "{} vroom".format(Wheels.name)

You shouldn't. The proper way to do this in Python is:

if not canMakeNoise:

and:

if canMakeNoise:

for the opposite. From PEP 8:

Don't compare boolean values to True or False using ==.

Yes: if greeting:
No: if greeting == True:
Worse: if greeting is True:

Just for the sake of completeness, you need to use == for comparisons. = is for assignment.
