How can I get around declaring an unused variable in a for loop?

If I have a list comprehension (for example) like this:

['' for x in myList]

Effectively making a new list that has an empty string for every element in a list, I never use the x. Is there a cleaner way of writing this so I don't have to declare the unused x variable?

_ is a standard placeholder name for ignored members in a for-loop and tuple assignment, e.g.

['' for _ in myList]

[a+d for a, _, _, d, _ in fiveTuples]

BTW your list could be written without list comprehension (assuming you want to make a list of immutable members like strings, integers etc.).

[''] * len(myList)

No. As the Zen puts it: Special cases aren't special enough to break the rules. The special case being loops not using the items of the thing being iterated and the rule being that there's a "target" to unpack to.

You can, however, use _ as variable name, which is usually understood as "intentionally unused" (even PyLint etc. knows and respect this).

It turns out that using dummy* (starting word is dummy) as the variable name does the same trick as _. _ is a known standard and it would be better to use meaningful variable names. So you can use dummy, dummy1, dummy_anything. By using these variable names PyLint won't complain.
