| is a separator.
|
|rstrip(...)
| S.rstrip() -> string or unicode
|
| 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
|
|split(...)
| S.split(]) -> list of strings
|
| 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

| Line breaks are not included in the resulting list unless keepends
| is given and true.
|
|startswith(...)
| S.startswith(prefix[, start[, end]]) -> bool
|
| Return True if S starts with the specified prefix, False otherwise.
| With optional start, test S beginning at that position.

|
|strip(...)
| S.strip() -> string or unicode
|
| 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
|
|swapcase(...)
| S.swapcase() -> string
|
| Return a copy of the string S with uppercase characters
| converted to lowercase and vice versa.
|
|title(...)
| S.title() -> string
|
| Return a titlecased version of S, i.e. words start with uppercase
| characters, all remaining cased characters have lowercase.
|
|translate(...)
| S.translate(table [,deletechars]) -> string
|
| Return a copy of the string S, where all characters occurring
| in the optional argument deletechars are removed, and the
| remaining characters have been mapped through the given
| translation table, which must be a string of length 256 or None.
| If the table argument is None, no translation is applied and
| the operation simply removes the characters in deletechars.
|
|upper(...)
| S.upper() -> string
|
| Return a copy of the string S converted to uppercase.
|
|zfill(...)
| S.zfill(width) -> string
|
