如何从 python 的列表中删除撇号？

Question

I need to remove apostrophes -> ' <- from a list, within python, without using any add-ons, so only built in functions.

Eg I need a list like:

lista = ['a', 'b', 'c', 'd']

into

lista = [ a, b, c, d]

I've tried using for with.replace or making the list into a string then replacing, but I haven't had anything work yet.

Any chance you could help?

Answer 1

You cannot remove apostrophes from a list because that's pretty much how you identify what a list is. However the apostrophes will not interfere with anything you do with the list. The apostrophes show that the elements are strings.

Answer 2

You can use str.join() to concatenate strings with a specified separator.

For example:

>>> strings = ['A', 'B', 'C']
>>> print(', '.join(strings))
A, B, C

Furthermore, in your case, str.format() may also help:

>>> strings = ['A', 'B', 'C']
>>> print('strings = [{}]'.format(', '.join(strings)))
strings = [A, B, C]
