str(object='') -> str str(bytes_or_buffer, encoding[, errors]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to 'strict'.

Return selfkey.

Implement iter(self).

Return a capitalized version of the string.

More specifically, make the first character have upper case and the rest lower case.

Return a version of the string suitable for caseless comparisons.

Return a centered string of length width.

Padding is done using the specified fill character (default is a space).

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

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

Encode the string using the codec registered for encoding.

encoding The encoding in which to encode the string. errors The error handling scheme to use for encoding errors. The 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 can handle UnicodeEncodeErrors.

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.

Return True if the string is a valid Python identifier, False otherwise.

Call keyword.iskeyword(s) to test whether string s is a reserved identifier, such as 'def' or 'class'.

Return True if the string is a lowercase string, False otherwise.

A string is lowercase if all cased characters in the string are lowercase and there is at least one cased character in the string.

Return True if the string is a numeric string, False otherwise.

A string is numeric if all characters in the string are numeric and there is at least one character in the string.

Return True if the string is printable, False otherwise.

A string is printable if all of its characters are considered printable in repr() or if it is empty.

Return True if the string is a whitespace string, False otherwise.

A string is whitespace if all characters in the string are whitespace and there is at least one character in the string.

Return True if the string is a title-cased string, False otherwise.

In a title-cased string, upper- and title-case characters may only follow uncased characters and lowercase characters only cased ones.

Return True if the string is an uppercase string, False otherwise.

A string is uppercase if all cased characters in the string are uppercase and there is at least one cased character in the string.

Concatenate any number of strings.

The string whose method is called is inserted in between each given string. The result is returned as a new string.

Example: '.'.join('ab', 'pq', 'rs') -> 'ab.pq.rs'

Return a left-justified string of length width.

Padding is done using the specified fill character (default is a space).

Return a copy of the string converted to lowercase.

Return a copy of the string with leading whitespace removed.

If chars is given and not None, remove characters in chars instead.

newbyteorder(new_order='S')

Return a new `dtype` with a different byte order.

Changes are also made in all fields and sub-arrays of the data type.

The `new_order` code can be any from the following:

* 'S' - swap dtype from current to opposite endian * '<', 'L' - little endian * '>', 'B' - big endian * '=', 'N' - native order * '|', 'I' - ignore (no change to byte order)

Parameters ---------- new_order : str, optional Byte order to force; a value from the byte order specifications above. The default value ('S') results in swapping the current byte order. The code does a case-insensitive check on the first letter of `new_order` for the alternatives above. For example, any of 'B' or 'b' or 'biggish' are valid to specify big-endian.

Returns ------- new_dtype : dtype New `dtype` object with the given change to the byte order.

Partition the string into three parts using the given separator.

This will search for the separator in the string. If the separator is found, returns a 3-tuple containing the part before the separator, the separator itself, and the part after it.

If the separator is not found, returns a 3-tuple containing the original string and two empty strings.

Return a copy with all occurrences of substring old replaced by new.

count Maximum number of occurrences to replace. -1 (the default value) means replace all occurrences.

If the optional argument count is given, only the first count occurrences are replaced.

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

Return the highest index in S where substring sub is found, such that sub is contained within Sstart:end. Optional arguments start and end are interpreted as in slice notation.

Return -1 on failure.

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

Return the highest index in S where substring sub is found, such that sub is contained within Sstart:end. Optional arguments start and end are interpreted as in slice notation.

Raises ValueError when the substring is not found.

Return a right-justified string of length width.

Padding is done using the specified fill character (default is a space).

Partition the string into three parts using the given separator.

This will search for the separator in the string, starting at the end. If the separator is found, returns a 3-tuple containing the part before the separator, the separator itself, and the part after it.

If the separator is not found, returns a 3-tuple containing two empty strings and the original string.

Return a list of the words in the string, using sep as the delimiter string.

sep The delimiter according which to split the string. None (the default value) means split according to any whitespace, and discard empty strings from the result. maxsplit Maximum number of splits to do. -1 (the default value) means no limit.

Splits are done starting at the end of the string and working to the front.

Return a copy of the string with trailing whitespace removed.

If chars is given and not None, remove characters in chars instead.

Return a list of the words in the string, using sep as the delimiter string.

sep The delimiter according which to split the string. None (the default value) means split according to any whitespace, and discard empty strings from the result. maxsplit Maximum number of splits to do. -1 (the default value) means no limit.

Return a list of the lines in the string, breaking at line boundaries.

Line breaks are not included in the resulting list unless keepends is given and true.

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. With optional end, stop comparing S at that position. prefix can also be a tuple of strings to try.

Replace each character in the string using the given translation table.

table Translation table, which must be a mapping of Unicode ordinals to Unicode ordinals, strings, or None.

The table must implement lookup/indexing via __getitem__, for instance a dictionary or list. If this operation raises LookupError, the character is left untouched. Characters mapped to None are deleted.

Return a copy of the string converted to uppercase.
