s = input(' Enter a monomial: ')
coeff, power = s.partition('x^')
print('{}x^{}'.format(int(coeff) * int(power), int(power) - 1)
I do not know what else is needed at the end of this code. Is there something that needs to be added in?

It's because you're not closing print function, one a close parenthesis at the end is missing. I suggest you to use some linter to debug and find warning and errors. The final code should be as below:
s = input(' Enter a monomial: ')
coeff, power = s.partition('x^')
print('{}x^{}'.format(int(coeff) * int(power), int(power) - 1))

That worked!!!. However when i ran the code I ended up with these errors: Enter a monomial: 2x^12 Traceback (most recent call last): File "./derivative.py", line 4, in <module> coeff, power = s.partition('x^') ValueError: too many values to unpack (expected 2)

Yep, that makes sense because partition is splitting the input in 3 parts and you're capturing just two of those
coeff, power. You can use split function instead and the replace that line as following: coeff, power = s.split('x^')Abdul Khan
That worked like a charm!!! Results have been achieved. Thank you for your advice.

You're welcome, we're here to help each other. Don't forget try to implement a
linter e.g. pylint to make debugging easier and you don't face this error next time :)You missed a bracket in last line:
print('{}x^{}'.format(int(coeff) * int(power), int(power) - 1))
