Learn alternatives with elif and else.
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.
Practice Print a grade with elif/else
Assign score = 75. Write if score >= 90: print("A"), elif score >= 70: print("B"), else: print("C").
Starter code
# Grade with elif/elseSample solution
score = 75
if score >= 90:
print("A")
elif score >= 70:
print("B")
else:
print("C")Expected output
B
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 If score is 75, what does this print? if score>=90: A elif score>=70: B else: C
- A
- Error
- C
- B Correct answer
Explanation: 75 >= 90 is False, 75 >= 70 is True, so B prints.
