Using strings in an if statement

I need a way for a users input to be used in an if statement:

print("Hello, World!")

name = input("What is your name?")

hobby = input("Cool, so " + name + " what do you do you for fun? You can say something like play, work, learn, etc.")

play = 'play'
work = 'work'
learn = 'learn'

if hobby = play
    print('awesome')

elif hobby = work
    print('must be busy')

elif hobby =  learn
    print('ha, me too')
