Python Error Handling

A program runs and, during running, is asked to divide by zero. The program crashes. This is an example of:

• a logic error
• a run-time error
• a logic error
• a user error

A syntax error in your code means:

• You have not used enough characters. 
• There was no defined index. 
• Python can't find a file to pass the code to. 
• There is an error with your typing and code structure. 

What will the output be from the following code?
print(Hello world!)

• Hello world!
• SyntaxError
• Hello world
• print(Hello world!)

Improper indentation is an example of what type of error?

• Syntax Error

• Run-time Error

• Semantic Error

To control for possible bad inputs, what keyword do I need:

def convI(s):

try:

num = int(s)

print('Success')

_______ ValueError:

print('Failed')

num = -1

• raise

• else

• Exception

• except

In the following code, I want to throw an exception if the denominator is not negative. What should I put after starting my function>

def div(n,d):

• if d == negative:

  try ('No negatives, moron')

• if d == negative:

  raise ('No negatives, moron')

• if d<0:

  raise Exception('I said no negative numbers, dimwit')

• if d<0:

  try Exception('I said no negative numbers, dimwit')

Which keyword should we use to printout only under the case of a successful running of a function?

• try

• raise

• finally

• else

In this partial code, what does the finally keyword do?

try:

k = n/d # raises divide by zero exception.

print(k)

# handles zerodivision exception

except ZeroDivisionError:

print("Can't divide by zero")

finally:

print('Looking Good')

• It will print out if there was no error in the function.

• It will print out 'Looking Good' whether or not there was an error in the function.

• It will only return 'Looking Good' to the developer in his developer's console.

• It will only print 'Looking Good' in the case of a zerodivision error

Within a function, is the following code:

print(f'Converted to {3/4}')

What will this print out?

• Syntax error due to the f in front of string

• 'Converted to 3/4'

• 'Converted to .75'

• Runtime error due to the f in front of the string.

Part of a code reads:

ans = input("The capital of Canada is? ")

if(ans == "Ottawa"):

print("You are wise")

else:

print("You are ignorant")

A user inputs "ottawa" and receives the response "You are ignorant".

What kind of error is that?

• Syntax

• ValueError

• Runtime

• Logic Error
