print(a-b+c)

This is one of quiz from python challenge. When I ran it on idle it show syntax error at line 2 for
def__init__(s,x):
for this semicolon thing. why so?

Answer 1

Write an space between def and __init__ :) (also with the other defs)

To @Vukan , the "self" word is just a convention, you can use any argument, but this must be also the same in all the class. (But the best option is always to use "self" to refer the self object :) )

Answer 2

you must use self for init

Answer 3

How so?
