Fix the syntax error in this while loop.
count = 0
while count < 5
print(count)
count += 1
Hint: 💡 Check the punctuation at the end of the while statement.
Issue: Missing colon at the end of the while condition.
count = 0
while count < 5:
print(count)
count += 1
This loop will run infinitely. Fix it.
x = 1
while x < 10:
print(x)
Hint: 💡 The loop variable is not being updated.
Issue: Missing increment operation causes infinite loop.
x = 1
while x < 10:
print(x)
x += 1
Fix the logical error in this loop that prints even numbers.
num = 0
while num <= 10:
if num % 2 == 1:
print(num)
num += 1
Hint: 💡 The condition checks for odd numbers instead of even.
Issue: The modulo condition checks for odd numbers (==1) when it should check for even numbers (==0).
num = 0
while num <= 10:
if num % 2 == 0:
print(num)
num += 1
Fix the indentation error in this nested while loop.
i = 1
while i <= 3:
j = 1
while j <= 3:
print(i, j)
j += 1
i += 1
Hint: 💡 The inner while loop should be indented inside the outer one.
Issue: Improper indentation of the inner while loop.
i = 1
while i <= 3:
j = 1
while j <= 3:
print(i, j)
j += 1
i += 1
This loop should print numbers 1 through 5 but has multiple issues. Fix them.
counter == 1
while counter < 6
print(counter)
counter =+ 1
Hint: 💡 Look for assignment vs comparison, missing colon, incorrect operator, and indentation.
Issue: Multiple errors: assignment vs comparison (==), missing colon, incorrect increment operator (=+), and missing indentation.
counter = 1
while counter < 6:
print(counter)
counter += 1
