Python script that does batch find and replace in txt files

[Syed Khalid]

Hi Albert,

Thank you for script.

I am getting the below error :

  File "EamClean.log", line 12
    with codecs.open(txt + "_out.txt", "wb", encoding="utf-8") as w:
       ^
SyntaxError: invalid syntax

Kindly do the needful.
