# Python – Lists Modulo

Sometimes we come across the situations in which we require to apply a particular function to each elements of two lists at similar index. These are quite similar and come up as application for certain utilities. Let’s discuss certain ways in which the modulo, i.e remainder of two lists can be performed.

Method #1 : Using `zip()` + list comprehension
The zip operation can be used to link one list with the other and the computation part can be handled by the list comprehension and hence providing a shorthand to this particular problem.

 `# Python3 code to demonstrate  ` `# Lists Modulo ` `# using zip() + list comprehension ` ` `  `# initializing lists  ` `test_list1 ``=` `[``3``, ``5``, ``2``, ``6``, ``4``] ` `test_list2 ``=` `[``7``, ``3``, ``4``, ``1``, ``5``] ` ` `  `# printing original lists  ` `print` `(``"The original list 1 is : "` `+` `str``(test_list1)) ` `print` `(``"The original list 2 is : "` `+` `str``(test_list2)) ` ` `  `# Lists Modulo ` `# using zip() + list comprehension ` `res ``=` `[i ``%` `j ``for` `i, j ``in` `zip``(test_list1, test_list2)] ` ` `  `# printing result ` `print` `(``"The modulo list is : "` `+` `str``(res)) `

Output :

```The original list 1 is : [3, 5, 2, 6, 4]
The original list 2 is : [7, 3, 4, 1, 5]
The modulo list is : [3, 2, 2, 0, 4]
```

Method #2 : Using `map()`
Using map function is most elegant way in which we can possibly perform the twining of a function with both the lists. Different operations other than modulo can also be applied over it.

 `# Python3 code to demonstrate  ` `# Lists Modulo ` `# using map() ` `from` `operator ``import` `mod ` ` `  `# initializing lists  ` `test_list1 ``=` `[``3``, ``5``, ``2``, ``6``, ``4``] ` `test_list2 ``=` `[``7``, ``3``, ``4``, ``1``, ``5``] ` ` `  `# printing original lists  ` `print` `(``"The original list 1 is : "` `+` `str``(test_list1)) ` `print` `(``"The original list 2 is : "` `+` `str``(test_list2)) ` ` `  `# Lists Modulo ` `# using map() ` `res ``=` `list``(``map``(mod, test_list1, test_list2)) ` ` `  `# printing result ` `print` `(``"The modulo list is : "` `+` `str``(res)) `

Output :

```The original list 1 is : [3, 5, 2, 6, 4]
The original list 2 is : [7, 3, 4, 1, 5]
The modulo list is : [3, 2, 2, 0, 4]
```
