从不需要的字符中删除数组

Question

I have an array as below:

>>>tags = ['frankie', "franki's car", 'car']

here I just want to replace double quotes to single quote, and remove the apostrophe from the array indexes.

So I expect to have something like below:

>>> tags
['frankie', 'frankis car', 'car']

any help? thanks.

Answer 1

You can use a list comprehension to remove the single quotes:

[t.replace("'", '') for t in tags]

The double quotes are an artefact of how Python represents string literals; it'll use single quotes unless there is a single quote in the string , at which point it'll use double quotes to avoid having to use a backslash to escape that character. If you have a string with both types Python uses single quotes again and escapes any double quotes in the value:

>>> "No single quotes"
'No single quotes'
>>> "A single quote: '"
"A single quote: '"
>>> "Both types: \" and '"
'Both types: " and \''

Demo:

>>> tags = ['frankie', "franki's car", 'car']
>>> [t.replace("'", '') for t in tags]
['frankie', 'frankis car', 'car']
