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

Question

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 e

Answer 1

_ 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)
