you should use return instead of print

def work_time(mathematic, chemistry, biology): 
    return mathematic*2 + chemistry*1 + biology*(0.5)
print("I will study " + str(work_time(1, 2,3) ) + " hours today")

none is telling you that the function is not returning a value so you must use the return keyword

See, when you don't use the return keyword, a function returns None. So when you print a function which returns None, Then None will be printing.

So, use the return keyword.

def work_time(mathematic, chemistry, biology): 
    print(mathematic*2 + chemistry*1 + biology*(0.5))
    return mathematic*2 + chemistry*1 + biology*(0.5)
print("I will study " + str(work_time(1, 2,3) ) + " hours today")

I can't see an image or code but things that can result to none can be:- 1.Not returning a blue from function 2.Keeping a boolean inactive 3.Not defining codes
