### __getattribute__(...)

x.__getattribute__('name') <==> x.name

Overrides: object.__getattribute__

### __getslice__(x, i, j)
(Slicling operator)

x[i:j]

Use of negative indices is not supported.

### __hash__(x)
(Hashing function)

hash(x)

Overrides: object.__hash__

### __new__(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

### __repr__(x)
(Representation operator)

repr(x)

Overrides: object.__repr__

### __str__(x)
(Informal representation operator)

str(x)

Overrides: object.__str__

### center(S, width, fillchar=...)

Return S centered in a string of length width. Padding is done using the specified fill character (default is a space)

Returns: string

### count(S, sub, start=..., end=...)

Return the number of non-overlapping occurrences of substring sub in string S[start:end]. Optional arguments start and end are interpreted as in slice notation.

Returns: int

### decode(S, encoding=..., errors=...)

Decodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme. Default is 'strict' meaning that encoding errors raise a UnicodeDecodeError. Other possible values are 'ignore' and 'replace' as well as any other name registerd with codecs.register_error that is able to handle UnicodeDecodeErrors.

Returns: object

### encode(S, encoding=..., errors=...)

Encodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme. Default is 'strict' meaning that encoding errors raise a UnicodeEncodeError. Other possible values are 'ignore', 'replace' and 'xmlcharrefreplace' as well as any other name registered with codecs.register_error that is able to handle UnicodeEncodeErrors.

Returns: object

### endswith(S, suffix, start=..., end=...)

Return True if S ends with the specified suffix, False otherwise. With optional start, test S beginning at that position. With optional end, stop comparing S at that position. suffix can also be a tuple of strings to try.

Returns: bool

### expandtabs(S, tabsize=...)

Return a copy of S where all tab characters are expanded using spaces. If tabsize is not given, a tab size of 8 characters is assumed.

Returns: string

### find(S, sub, start=... , end=...)

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.

Returns: int

### istitle(S)

Return True if S is a titlecased string and there is at least one character in S, i.e. uppercase characters may only follow uncased characters and lowercase characters only cased ones. Return False otherwise.

Returns: bool

### join(S, sequence)

Return a string which is the concatenation of the strings in the sequence. The separator between elements is S.

Returns: string

### ljust(S, width, fillchar=...)

Return S left justified in a string of length width. Padding is done using the specified fill character (default is a space).

Returns: string

### lstrip(S, chars=...)

Return a copy of the string S with leading whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping

Returns: string or unicode

### partition(S, sep)

Searches for the separator sep in S, and returns the part before it, the separator itself, and the part after it. If the separator is not found, returns S and two empty strings.

Returns: (head, sep, tail)

### replace(...)

S.replace (old, new[, count]) -> string

Return a copy of string S with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced.

### rfind(S, sub, start=... , end=...)

Return the highest 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.

Returns: int

### rjust(S, width, fillchar=...)

Return S right justified in a string of length width. Padding is done using the specified fill character (default is a space)

Returns: string

### rpartition(S, sep)

Searches for the separator sep in S, starting at the end of S, and returns the part before it, the separator itself, and the part after it. If the separator is not found, returns two empty strings and S.

Returns: (tail, sep, head)

### rsplit(S, sep=... , maxsplit=...)

Return a list of the words in the string S, using sep as the delimiter string, starting at the end of the string and working to the front. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator.

Returns: list of strings

### rstrip(S, chars=...)

Return a copy of the string S with trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping

Returns: string or unicode

### split(S, sep=... , maxsplit=...)

Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator.

Returns: list of strings

Returns: list of strings

### startswith(S, prefix, start=..., end=...)

Return True if S starts with the specified prefix, False otherwise. With optional start, test S beginning at that position. With optional end, stop comparing S at that position. prefix can also be a tuple of strings to try.

Returns: bool

### strip(S, chars=...)

Return a copy of the string S with leading and trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping

Returns: string
