7.2.10.3. Token¶

class Token(*args)[source]¶

It constructs a unique constant that behaves like a string.

Example:

>>> s = Token('string')
>>> s
string
>>> s == 'string'
False
>>> s == Token('string')
False
>>> {s: 1, Token('string'): 1}
{string: 1, string: 1}
>>> s.capitalize()
'String'

`partition`	Partition the string into three parts using the given separator.
`replace`	Return a copy with all occurrences of substring old replaced by new.
`rfind`	Return the highest index in S where substring sub is found, such that sub is contained within S[start:end].
`rindex`	Return the highest index in S where substring sub is found, such that sub is contained within S[start:end].
`rjust`	Return a right-justified string of length width.
`rpartition`	Partition the string into three parts using the given separator.
`rsplit`	Return a list of the words in the string, using sep as the delimiter string.
`rstrip`	Return a copy of the string with trailing whitespace removed.
`split`	Return a list of the words in the string, using sep as the delimiter string.
`splitlines`	Return a list of the lines in the string, breaking at line boundaries.
`startswith`	Return True if S starts with the specified prefix, False otherwise.
