46bc6738d7 Add doctest to maths/sieve_of_eratosthenes.py and remove other/finding_primes.py (#1078) 
Both of the two files implemented sieve of eratosthenes.
However, there was a bug in other/finding_primes.py, and the time complexity was larger than the other.
Therefore, remove other/finding_primes.py and add doctest tomaths/sieve_of_eratosthenes.py.

add1aef064 Rename average.py to average_mean.py (#939)

2b365284c8 Removed Unnecessary Assignment for 'error' Var (#920) 
`error = abs(f(a))` was declared on line 24 and line 32. It is unnecessary to have in both places.
I removed the second instance since it wastes resources to keep redefining the variable inside the for loop.
This fixes an [issue found by lgtm](66c4afbd0f/files/maths/newton_raphson.py)
