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

A verbose way is:

newList = []
while len(newList) < len(mylist):
    newList.append('')

You avoid declaring an used variable this way.

Also you can append both mutable and immutable objects (like dictionaries) into newList.

Another thing for python newbies like me, '_', 'dummy' are a bit disconcerting.
