Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Please document the error you see properly before raising an issue. You're not helping anybody with that.
Anyways,
ValueError: math domain errorshould be very indicative of what's the problem. So it's your code's issue.I have the same error with Python's math module. Tried on Python 2 and Python3, error remains.
Can you screenshot the error? I'm interested why you are getting an error.
It might because you are using
math.sqrt(n)but n can be negative. √-1 = i. i is a complex number. You cannot square root a negative number - otherwise it ends up being a complex number (imaginary). You must check if n >= 0I had the same issue. Not sure why some encounter it while others don't
Nothing wrong with that. But
lambdausually makes the readability worse; and list comprehension is usually preferred overmap(which is not so "pythonic").Did you use Python2 or Python3? There were some problems reported with Python3, IIRC.
