elif and else

Learn alternatives with elif and else.

elif (else if) adds a second condition. else runs when no condition is true:

score = 75
if score >= 90:
    print("A")
elif score >= 70:
    print("B")
else:
    print("C")

Python tries conditions in order; the first True block runs. else is always last and takes no condition.

The order of if/elif/else

In an if/elif/else chain Python checks from top to bottom. The first True condition's block runs; the rest are skipped.

temp = 25
if temp > 30: print("Hot")
elif temp > 20: print("Mild")
elif temp > 10: print("Cold")
else: print("Freezing")

The order matters: write narrow ranges first, wider ones later.

Assign score = 75. Write if score >= 90: print("A"), elif score >= 70: print("B"), else: print("C").

Show example solution

score = 75
if score >= 90:
    print("A")
elif score >= 70:
    print("B")
else:
    print("C")
