Trying to pass a variable as a function argument that is inputted by the user. Getting some weird errors. Any help will be appreciated.

Error that I'm getting:

Traceback (most recent call last):

File "python", line 14, in

File "python", line 6, in square

TypeError: unsupported operand type(s) for ** or pow(): 'unicode' and 'int'

```
def square(original):
"""Returns the square of a number."""
original = raw_input('Enter a number to be squared:')
squared = original**2
print "%d squared is %d." % (n, squared)
return squared
#Call the function
square(original)
```
