Errors and Exceptions Homework¶
Problem 1¶
Handle the exception thrown by the code below by using try and except blocks.
In [1]:
for i in ['a','b','c']:
print(i**2)
--------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-1-c35f41ad7311> in <module>() 1 for i in ['a','b','c']: ----> 2 print(i**2) TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'int'
Problem 2¶
Handle the exception thrown by the code below by using try and except blocks. Then use a finally block to print 'All Done.'
In [2]:
x = 5
y = 0
z = x/y
--------------------------------------------------------------------------- ZeroDivisionError Traceback (most recent call last) <ipython-input-2-6f985c4c80dd> in <module>() 2 y = 0 3 ----> 4 z = x/y ZeroDivisionError: division by zero
Problem 3¶
Write a function that asks for an integer and prints the square of it. Use a while loop with a try, except, else block to account for incorrect inputs.
In [3]:
def ask():
pass
In [4]:
ask()
Input an integer: null An error occurred! Please try again! Input an integer: 2 Thank you, your number squared is: 4
