How to remove footnotes anchors ([1]) from a scraped wiki page?

Question

I have a bunch of data that looks like this:

Bigtable,[4] MariaDB[5]

How do I use Python re library to remove those [4] quotations?

Answer 1

You can use the re.sub to remove those scientific quotations

>>> import re
>>> s = "Bigtable,[4] MariaDB[5]"
>>> re.sub(r'\[.*?\]', '', s)
'Bigtable, MariaDB'

The regex \[.*?\] will match the substrings that starts with [ and ends with ] with as few character inside the brackets as possible

If you only want to remove square brackets with numbers inside, use this regex instead: \[\d+\]
