New submission from andy ye <andy.ye.jx at gmail.com>:

data = 'abcddd'
# True
data.find('a', 0)

# False
data.find('a', start=0)

# document
class str(obj):

    def find(self, sub, start=None, end=None): # real signature unknown; restored from __doc__
        S.find(sub[, start[, end]]) -> int
        Return the lowest index in S where substring sub is found,
        such that sub is contained within S[start:end].  Optional
        arguments start and end are interpreted as in slice notation.
        Return -1 on failure.
        return 0
