If and Else statement Variable Question in Python

Question

I am still pretty new to Python and learning! I searched around and some postings seem too complex for me at this time. Wondering why the car_brandp below is not joining with "and quite expensive" after the else function initiates? The first else line prints fine but it seems like I can't put that message as a variable?

I got the None Type error

car_brand =input ("What is the best car brand? ")
if car_brand == ("Range Rover"):
    print (car_brand + " is the best car brand ever!")
else:
    car_brandp = print (car_brand + " is just personal taste..")
    print (car_brandp + " and quite expensive...")

print returns None. car_brandp = print() will always cause car_brandp to be None — roganjosh

print is used to print out to standard output. Here you need an assignment to a variable. car_brandp = car_brand + " is just personal taste..". — Austin

Or, from 3.6 f'{car_brand} is just personal taste..' (also available in multi-line version that won't render properly in a comment) — Ben

This line:

car_brandp = print (car_brand + " is just personal taste..")

is suppose to be:

car_brandp = (car_brand + " is just personal taste..")

By the way, it's worth pointing out that the reason why OP was getting NoneType error was because print() returns None

@DroidX86 why would that turn None when I have a string after print () ? I know that if I do print () it prints none, but i had a string in there with a variable from the previous line... its like a mystery to me.. maybe I just don't have the basics down and I should revert =[

@bestcoderNAjk That's the behaviour of print. No matter what argument you give it - it'll send it to stdout and return None to you. programiz.com/python-programming/methods/built-in/print

"print" is a procedure to display something in the console. A procedure differs from a function as it is not meant to return something of value, but rather perform something as a side effect (it will do something useful but you cannot interact with it). You may not assign the return value of the print function as it is meaningless.

Since you are still new to Python, it is a good idea to learn the proper habits early. In particular, PEP8 contains valuable information on style and conventions that most Python developers follow. Such recommendations are optional, but when followed, they help other developers understand your code better.

car_brand = input("What is the best car brand? ")

if car_brand == "Range Rover":
    msg = car_brand + " is the best car brand ever!"
else:
    msg = car_brand + " is just personal taste.."
    msg += " and quite expensive..."

print(msg)

Never knew I can write it this way as well.. I was following a youtube video and a python crash course book. Thanks a lot!

There are even better ways to build strings, I will let you discover them by yourself. Have fun on your journey, it's the most important part. If this answer was useful to you, please consider upvoting and/or accepting it.

print() is like a void function in other languages. So, it does something, but it returns nothing (None, in python, like null in other languages).

So, in your next line, you are trying to add

None + "personal taste"

and you get an error because addition of string and None is not defined

So, you options are

consecutive prints
concatenate strings eg print( str(brand) + "personal taste")
formatted strings eg print( f'{brand} personal taste')
