Python RegEx to make '][?][?]' disappear-CodePudding

There are strings in Stack Exchange Markdown that need to be removed (set to null string). I think Python RegEx would be the best solution. Here are the strings:

[![male end][1]][1]
[![female end][2]][2]

It probably doesn't matter to those familiar with Stack Exchange Markdown but the original markdown above can be found in this post in Stack Exchange Electrical Engineering.

Note that [![ prefix is for a picture link. Other links will be [[ or even [ prefix.

CodePudding user response：

Use re.sub to remove each markup tag:

inp = "Hello [![male end][1]][1] World [![female end][2]][2] Goodbye"
output = re.sub(r'\[!\[.*?\]\[\d \]\]\[\d \]', '', inp)
print(output)  # Hello  World  Goodbye
