Output:

Q2.5

What does this code print? Type it in and run to verify:

total = 1
for i in range(1, 5):
    total = total * i
print(total)

Q3

Read the Code and Find the Errors

Each snippet has an error. Fix the code so it runs correctly.

Q3.1 — Fix the If Statement

This should print "big" if x is greater than 3. Find the error:

x = 5
if x > 3;
    print("big")

Q3.2 — Fix the Even Number Finder

This should print even numbers from 1 to 9. Find the error:

for i in range(1, 10):
    if i % 2 = 0:
        print(i)

Q3.3 — Fix the String Replace

This should replace "hello" with "hi". Find the error:

text = "hello"
print(text.Replace("hello", "hi"))

Q3.4 — Fix the Max Function

This should print the largest number in the list. Find the error:

numbers = [5, 10, 15]
print(max[numbers])

Q3.5 — Fix the Age Check

This should print "Young adult" if age is between 18 and 30. Find the error:

age = 20
if age > 18 and age < 30 print("Young adult")

Q3.6 — Fix the Loop

This should print numbers 0 through 4. Find and fix the error:

for i in range(5) print(i)
