can someone please tell me the correct answer. I've tried to fix it a million time.

5,675 PointsHey Grace! This one can be tricky. Here's how I completed it:
First, create the function and set the parameters, like you did. Then we can write our try and except block.
def squared(x):
try:
In the try portion, we're supposed to return the square of the input, but only if it can be converted into an integer. We're just telling it to try to return int(x) * int(x).
def squared(x):
try:
return int(x)**2
Then, in the except portion, we tell it to catch a ValueError. This is the error that pops up when x can't be converted into an integer. When this happens, we're supposed to return the argument multiplied by its length.
def squared(x):
try:
return int(x)**2
except ValueError:
return len(x) * x
