Word replace with string

[dabozz]

Hi,

I would like to replace a word with a variable in a html file.
My code is:

name = raw_input("Name: ")
s = open("helloworld.html").read()
s = s.replace('YourNameHere', name)
f = open("helloworld.html", 'w')
f.write(s)
f.close()

But it is not working..

So if the user add his name, on the html file it should be appear.
For example: YourNameHere should replaced with "John Smith".

The error message:
Traceback (most recent call last):
File "C:/Users/tmate/PycharmProjects/Tesztprojekt/fb.py", line 12, in <module>
s = s.replace('YourNameHere', name)
NameError: name 'name' is not defined

Any suggestion?

Thanks,
Tamas
