How can I determine if a string is contained in a bigger string?

How can I find the position of a substring in a string?

if string.find(mystring, "foo") >= 0:
    ...

or

string.index(mystring, "foo")
...

The latter raises a ValueError exception if the substring isn't found.

For more info, see the "string" chapter in the library reference:
