Applying 'for' in the list by fives-CodePudding

I want to apply a 'for' in a list by fives.

For example;

list = [1,2,3,4,5,6,7,8,9,10]

for a in list:
    print(a)

output:

After these 5 ends, i want it to move to the second 5.

Thanks.

This is how you can loop through elements 0-4 of your list.

numbers = [1,2,3,4,5,6,7,8,9,10]

for number in numbers[0:5]:
    print(number)

I'm not sure what you mean by "After these 5 ends, i want it to move to the second 5." Are you wanting the code to pause then continue counting?

CodePudding user response：

It seems extremely non-idiomatic to write code like this, but perhaps you are looking for something like:

#!/usr/bin/env python


a = [1,2,3,4,5,6,7,8,9,10,11,12]
t = iter(a)
try:
    while True:
        counter = 1
        while i := t.__next__():
            print(i)
            if counter == 5:
                break
            counter  = 1
        print("Finished group")
except StopIteration:
    pass

CodePudding user response：

you may be looking for this in collections

chunked(iterable, n) returns an iterable of lists, each of length n (except the last one, which may be shorter);

ichunked(iterable, n) is similar but returns an iterable of iterables instead.
