Chapter 2 of the Library Reference is a wealth of information about built-in types:
In particular this page
find( sub[, start[, end]])
Return the lowest index in the string where substring sub is found, such that sub is contained in the range [start, end). Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.
index( sub[, start[, end]])
Like find(), but raise ValueError when the substring is not found.
