Multiple, Specific, Regex Substitutions In Python

What I would like to do is to make specific substitions in a given text. For example, '<' should be changed to '[', '>' to ']', and so forth. It is similar to the solution gi

Solution 1:

import re

defmultiple_replace(dict, text):
  # Create a regular expression  from the dictionary keys
  regex = re.compile(r'(%s)' % "|".join(dict.keys()))
  return regex.sub(lambda mo: dict[
      [ k for k indictif
      re.search(k, mo.string[mo.start():mo.end()])
      ][0]], text)

d = { r'ba[rz]*' : 'bar', '<' : '[' }
s = 'barzzzzzz <'print multiple_replace(d, s)

Gives:

bar [

Solution 2:

Just do multiple sub calls.

On an unrelated note, Jargon File to the rescue: Metasyntactic variables, foo.
