Have you tried it with a proper fraction, like 1/2 or 4/11? As continued 
fractions, they ought to print out:

0 2        # 1/2 = 0 + 1/2
0 2 1 3    # 4/11 = 0 + 1/(2 + 1/(1 + 1/3))

but it doesn't.

I'm afraid I have no idea what you are talking about. What are the 
PyCharm problems, and what's "check feature"?

Is it possible that you are supposed to write a function?

def contfract(fraction):
    # code as before


And then call it like this?


frac = input("Enter a fraction like num/den ")
contfract(frac)
