Question

#Fibonacci code. huh?

b + a
elif:
while a > 21:
print(a)
a = b + a

Answer 1

It showed error
It said that the error at elif:
Syntax error

Answer 2

Why you are using elif first.

The syntax of if else statement is

if(...):
//Body
elif(...):
//Body
.
.
.
else:
//Body

This code gives you syntax error because you are not using if first , you are start using elif first which is syntactical error.
