bug in str.startswith() and str.endswith()

Show key headers only | View raw

I've tried this in 2.5 - 3.2:

--> 'this is a test'.startswith('this')
True
--> 'this is a test'.startswith('this', None, None)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: slice indices must be integers or None or have an __index__ 
method

The 3.2 docs say this:

str.startswith(prefix[, start[, end]])
Return True if string starts with the prefix, otherwise return False. 
prefix can also be a tuple of prefixes to look for. With optional start, 
test string beginning at that position. With optional end, stop 
comparing string at that position

str.endswith(suffix[, start[, end]])
Return True if the string ends with the specified suffix, otherwise 
return False. suffix can also be a tuple of suffixes to look for. With 
optional start, test beginning at that position. With optional end, stop 
comparing at that position.

Any reason this is not a bug?
