how to use try and except?

Question

Create a function that will divide 2 numbers and return the result. The function will accept 2 arguments. Use a try statement and the ZeroDivisionError exception type to catch divide by zero errors. Inside the exception, print out “invalid argument”.

Hello!

You'll want to define the function with a name of your choosing. Let's use `divideTwoNums()`

Then you'll want to pass in two arguments into the function and use them to attempt the division.

Let's call them `firstNum` and `secondNum`.

The try-block will attempt the division and return the result if successful.

The except-block will catch specifically the ZeroDivisionError type and do a print statement if it catches that error type.

Below is how you can start it:

def divideTwoNums(firstNum, secondNum):

try:

# Fill in the logic and return the result

except ZeroDivisionError:

# What do you want to happen when someone passes in 0 for the secondNum variable?

# Example Usage

print(divideTwoNums(10,5)) # This should output 2.0

print(divideTwoNums(5, 0)) # This should output a println when dividing by 0
