I am very new to python (as im a perl developer, sorry !) and am still =
trying to get my head around the regular expression model.
Python does not seem to have perls variable interpolation (or does it ?)
I have an HTML file, example below:
<HTML>
<HEAD>
<BODY>
This is a test of things<BR>
<!-- Replace Me -->
</BODY>
</HTML>
This is my template file. I want to open it and replace the <!-- Replace =
Me --> value with a new value:
Heres my code:
import re
f =3D open("C:\\www.timemanager.com\\test.html")
fileContent =3D f.read()
f.close
newVal =3D "Heres the replacement code which means it worked"
key =3D "Replace Me"
re.sub('\<!--\s*' + key + '\s*--\>',newVal,fileContent)
print fileContent
raw_input("ok done")=20
it wont work, please can someone assist in explaining where I am going =
wrong, thanks a mill
