for v in enumerate(nums): print(v)

Question

Why did they use v. Because I tried with different alphabets and it worked. Away reason for the v.

Answer 1

No, there is reason for taking a specific letter. You can take any letter in place of v. Not just letter, you can take words, for example num, val etc.

Answer 2

V for Vendetta... ✌️

🙄 eh, sorry no, it's just "v" like Variable.
It's a shortcut or memonic technic, like "i" for Iterable (in FOR loop)

But you always can use another name (or letter).

Answer 3

Am sure it does not matter provided it follows the rule in declaring a variable.
