I want to loop this format using python-CodePudding

I have 3 list a = ["1", "2", "3", "4", "5", "6"] b = ['a', 'b', 'c'] c = ["13", "14"] and the format is : 1 13 a 2 13 b 3 13 c 4 14 a 5 14 b 6 14 c (all the character in next lines (stackoverflow shows in a single line))

`How to I get the above format

Thanks`

CodePudding user response：

You can use itertools.cycle to get the list b to cycle round and have an adapter with itertools.repeat to get c to repeat its items:

from itertools import repeat, cycle

def repeat_elements(iterable, repeat_count):
    for element in cycle(iterable):
        yield from repeat(element, repeat_count)

a = ["1", "2", "3", "4", "5", "6"]
b = ['a', 'b', 'c']
c = ["13", "14"] 

for x,y,z in zip(a, cycle(b), repeat_elements(c, 3)):
    print(x,z,y)

Output as requested

Note that this code relies on zip stopping the iteration when a has run out of elements. Both cycle and the adapter repeat_elements are going to loop endlessly.

Below Code will print the required sequence with all characters in new line.

for i in c:
    for j in b:
        for k in a:
            print(k,i,j,sep='\n')
