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

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).

Add the following comment after the for loop on the same line:

#pylint: disable=unused-variable

for i in range(100): #pylint: disable=unused-variable

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.

_ 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)
