>>> help(str.capitalize)
Help on method_descriptor:

capitalize(...)
    S.capitalize() -> string

    Return a copy of the string S with only its first character
    capitalized.

>>> help(str.center)
Help on method_descriptor:

center(...)
    S.center(width[, fillchar]) -> string

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

>>> help(str.count)
Help on method_descriptor:

count(...)
    S.count(sub[, start[, end]]) -> int

    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.

>>> help(str.decode)
Help on method_descriptor:

decode(...)
    S.decode([encoding[,errors]]) -> object

    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 registered with codecs.register_error that is
    able to handle UnicodeDecodeErrors.

>>> help(str.encode)
Help on method_descriptor:

encode(...)
    S.encode([encoding[,errors]]) -> object

    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.

>>> help(str.endswith)
Help on method_descriptor:

endswith(...)
    S.endswith(suffix[, start[, end]]) -> bool

    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.

>>> help(str.expandtabs)
Help on method_descriptor:

expandtabs(...)
    S.expandtabs([tabsize]) -> string

    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.

>>> help(str.find)
Help on method_descriptor:

find(...)
    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.

>>> help(str.format)
Help on method_descriptor:

format(...)
    S.format(*args, **kwargs) -> string

    Return a formatted version of S, using substitutions from args and kwargs.
    The substitutions are identified by braces ('{' and '}').

>>> help(str.index)
Help on method_descriptor:

index(...)
    S.index(sub [,start [,end]]) -> int

    Like S.find() but raise ValueError when the substring is not found.

>>> help(str.isalnum)
Help on method_descriptor:

isalnum(...)
    S.isalnum() -> bool

    Return True if all characters in S are alphanumeric
    and there is at least one character in S, False otherwise.

>>> help(str.isalpha)
Help on method_descriptor:

isalpha(...)
    S.isalpha() -> bool

    Return True if all characters in S are alphabetic
    and there is at least one character in S, False otherwise.

>>> help(str.isdigit)
Help on method_descriptor:

isdigit(...)
    S.isdigit() -> bool

    Return True if all characters in S are digits
    and there is at least one character in S, False otherwise.

>>> help(str.islower)
Help on method_descriptor:

islower(...)
    S.islower() -> bool

    Return True if all cased characters in S are lowercase and there is
    at least one cased character in S, False otherwise.

>>> help(str.isspace)
Help on method_descriptor:

isspace(...)
    S.isspace() -> bool

    Return True if all characters in S are whitespace
    and there is at least one character in S, False otherwise.
