[Basic] Never use "for i in range(len(sequence)):"

[nilamo]

maybe add a zip in a for loop example as questioned here

for i in correct:
#how could i compare here the two array without writing it in the C way?

for item, check in zip(received, correct):
    if item == check:
        coincident += 1

 

 Wouldn't it be better to avoid an intermediate variable or zipping, and instead just do set arithmetic?

coincident = len(set(received) & set(correct))

Unless one or both of those are a generator/stream to something that might not all fit into memory, I suppose.
