Iteration protocol

#1

I didn’t get why is yrange not consumable multiple times while zrange is in python iteration protocol video ?

hey @stutijain578 ,
it is because on iterating over yrange it results in an output value and hence when we reach the end of that range it stops and cannot be used further , whereas when we iterate over zrange , it generates an another iterator class every time (which works the same as yrange ).

for example in zrange:
if we iterate it 10 times ,
it means that we are generating 10 iterators and each of these iterators can create a list of values from 1-10 , hence we get 10 lists of 1 - 10.

where as if we had iterated over yrange, then in 1 iteration we would have reached the end value in range specified and cannot iterate over it further.

I hope this would have resolved your doubt.
