Q2.5

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

for x in range(10, 20):
    if x % 2 == 0:
        print("hi")
        print(x)

# Type the code above and run it to see the output

Q2.6

x = 50
if x > 10:
    if x > 25:
        print("ok")
        if x > 60:
            print("good")

Q3

Read the Code and Find the Errors

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

Q3.1 — Fix the Leap Year Program

This program should check if a year is a leap year. Find and fix the errors:

year = 2000
if year % 4 = 0:
    print(year, "is a leap year")
else
    print(year, "is not a leap year")
else:
    print(year, "is not a leap year")

Q3.3 — Fix the Age Check

This should print "Teenager" if age is between 10 and 18. Find the error:

age = 15
if age > 10 and < 18:
    print("Teenager")

Q3.6 — Fix the Comparison

This should print "x is ten" when x equals 10. Find the error:

x = 10
if x = 10:
    print("x is ten")

Q3.8 — Fix the Greater/Smaller Check

Find and fix the error:

a = 5
if a > 3
    print("Greater")
else:
    print("Smaller")

Q3.10 — Fix the Pass Check

This should print "Pass" if marks are 40 or above. Find the error:

marks = 70
if marks = 40:
    print("Pass")
