I'm a new to Python

Hey guys, nice forums you have here.
Anyway I've started to learn python, today infact, as I've heard its a good language to learn, I have some experience in BASIC and a little in C from using Linux. I was wondering if there was a function in Python that did the same as mid$() in BASIC, I've searched for tutorials on string manipulation etc, but could not find anything on this function.
Thanks.

I have no experiance in BASIC, so please explain what the mid$() function does, then i can help you out.

Ok, i searched google and i didn't find much, from what i found i think that mid$() finds the length of a string.

In Python we have the len() function.
Example 1

>>> len("hello")

5

Example 2:

>>> variable = "hello"

>>>len(variable)

5

I think the mid function returns a part of a string. In python, you can consider a string as a list of characters and use the [] notation to get slices. See this tutorial on Python string handling or some simple code:

>>> s = "Hello World!"

>>> s[0]

'H'

>>> s[0:5]

'Hello'

>>> s[:5]

'Hello'

>>> s[6:13]

'World!'

>>> s[6:]

'World!'

>>> s[-1]

'!'

SubStr$ = MID$(MainStr$, Start% [, Length%])

returns a substring of a string

SubStr$ = MID$("abcdefg",3,4)

' Result: SubStr$ will equal "cdef"



SubStr$ = MID$("abcdefg",2)

' Result: SubStr$ will equal "bcdefg"

Ok, so my examples are correct to what he wants.
Thanks Dietrich for clearing that up.
