Common exception types in Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

intermediate

What is the output of this code?

Look at the code below. What will it print when run?

Python

try:
    x = 5 / 0
except ZeroDivisionError:
    print("Error caught")

A ZeroDivisionError

B Error caught

C 5

D No output

💡 Hint

Think about what happens when you divide by zero in Python.

Dividing by zero raises a ZeroDivisionError. The except block catches it and prints "Error caught".

❓ Predict Output

intermediate

What error does this code raise?

What error will this code produce when run?

Python

my_list = [1, 2, 3]
print(my_list[5])

A IndexError

B KeyError

C TypeError

D ValueError

💡 Hint

Think about what happens when you try to access a list element with an invalid index.

Accessing an index that is out of range in a list raises an IndexError.

What is the output of this code?

What will this code print?

Python

d = {'a': 1, 'b': 2}
try:
    print(d['c'])
except KeyError:
    print('Key not found')

A KeyError

B 1

C Key not found

D None

💡 Hint

What happens when you try to access a dictionary key that does not exist?

Accessing a missing key in a dictionary raises a KeyError, which is caught and prints 'Key not found'.

❓ Predict Output

advanced

What error does this code raise?

What error will this code produce?

Python

x = 'hello'
print(x + 5)

A TypeError

B ValueError

C NameError

D SyntaxError

💡 Hint

Think about adding a string and a number.

You cannot add a string and an integer directly, so Python raises a TypeError.

❓ Predict Output

What is the output of this code?

What will this code print when run?

Python

try:
    a = int('abc')
except ValueError:
    print('Conversion failed')
else:
    print('Conversion succeeded')

A No output

B Conversion succeeded

C ValueError

D Conversion failed

💡 Hint

What happens when you try to convert a non-numeric string to int?

int('abc') raises a ValueError, so the except block runs and prints 'Conversion failed'.
