Well, if you tell us, what the function does, i am pretty sure, that somebody can answer your qouestion...

It takes a section of a string. In Python, this is built into the language:

You can take individual characters by typing the index in square brackets after the variable name:
# str[1] = "h"
# str[12] = "r"

You can also take slices using the colon ( : ) operator - the first number is the index of the first letter; the second is the the index of the first letter after the end of the slice.
# str[1:3] = "his"
# str[12:17] = "ring."

If you leave the slice open, it carries on until it hits the beginning or the end:
# str[8:] = "a string."
# str[:3] = "Thi"
# str[:] = "This is a string."

You can also use negative numbers to refer to characters from the end:
# str[-2] = "g"
# str[1:-2] = "his is a strin"

Enjoy.

You mean, that a normal assignment thingy like '=' is not built in in VB??
Woah, I always thought these would make the core of each language...
Weird world

My dad tells me that MID, RIGHT and LEFT are holdovers from the old Mbasic. Python takes care of that with slicing.

Did you even read my post, Fred? I explained splicing, not assignment.

I forgot to mention; you can also change slices (and you don't even have to stick to the same number of characters):
str[1:3] = "xyz"
print str
# str = "Txyzs is a string."

Read and misunderstood...
I thought you were talking about assignment, when you said, that it 'takes' a string, and the showed, what you could do with this datatype.

Fred

If you are talking about normal strings, the you cannot. They do not support slice replacement. Gives the following error:
All other slice thingies work though.
