elif — Expert Playground

Short for 'else if'; adds another condition to an if chain

Python Playground

import dis

def grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    else:
        return "F"

dis.dis(grade)

# Each elif compiles to:
# COMPARE_OP, POP_JUMP_IF_FALSE -> next elif
# There is NO optimization to a jump table
# Each condition is tested sequentially

Output

Click "Run" to execute your code

elif compiles to a chain of compare + conditional jump instructions. Unlike switch/case in C, there is no jump table — each condition is evaluated one by one until a match is found.

Challenge

Try modifying the code above to explore different behaviors. Can you extend the example to handle a new use case?
