What is wrong with my python code? I get a line 3 stynax error

Question

atomicNumber = input ("")
protons = input("")
neutrons = 'atomicNumber' - 'protons'
print (neutrons)

Answer 1

What you get from input is a string , so you are trying to subtract two strings, which isn't correct.

Just convert what you get from input to a number, ie:
atomicNumber=int(input(''))
and same for protons
