Thanks for the quick hint. I had to lookup how to apply filters but it was 
rather straightforward (only a bit hard to infer the structure of the 
python objects from the Haskell data type documentation).
In case someone is interested, the following hacky filter worked at first 
glance.

#!/usr/local/bin/python3

"""
Pandoc filter to convert code blocks of certain language classes to code 
class
"""

from pandocfilters import *

def addCodeClass(key, value, format, meta):
  if key == 'CodeBlock':
    [[ident, classes, keyvals], code] = value
    if "python" in classes:
      classes.remove("python")
      classes.append("code")
    return CodeBlock([ident, classes, keyvals], code)

if __name__ == "__main__":
  toJSONFilter(addCodeClass)
