Return True if there are only numeric characters in S,
False otherwise.
- isspace(...)
- S.isspace() -> bool
Return True if all characters in S are whitespace
and there is at least one character in S, False otherwise.

character in S, i.e. upper- and titlecase characters may only
follow uncased characters and lowercase characters only cased ones.
Return False otherwise.
- isupper(...)
- S.isupper() -> bool
Return True if all cased characters in S are uppercase and there is
at least one cased character in S, False otherwise.
- join(...)
- S.join(sequence) -> unicode
Return a string which is the concatenation of the strings in the
sequence. The separator between elements is S.
- ljust(...)
- S.ljust(width[, fillchar]) -> int
Return S left justified in a Unicode string of length width. Padding is
done using the specified fill character (default is a space).
- lower(...)
- S.lower() -> unicode
Return a copy of the string S converted to lowercase.
- lstrip(...)
- S.lstrip([chars]) -> unicode
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 a str, it will be converted to unicode before stripping
- replace(...)
- S.replace (old, new[, maxsplit]) -> unicode
Return a copy of S with all occurrences of substring
old replaced by new. If the optional argument maxsplit is
given, only the first maxsplit occurrences are replaced.
- rfind(...)
- S.rfind(sub [,start [,end]]) -> int
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.

Like S.rfind() but raise ValueError when the substring is not found.
- rjust(...)
- S.rjust(width[, fillchar]) -> unicode
Return S right justified in a Unicode string of length width. Padding is
done using the specified fill character (default is a space).
- rsplit(...)
- S.rsplit([sep [,maxsplit]]) -> list of strings
Return a list of the words in 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, any whitespace string
