7.2.8.3. Token¶

class Token[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'

Methods

`capitalize`	Return a capitalized version of S, i.e.
`casefold`	Return a version of S suitable for caseless comparisons.
`center`	Return S centered in a string of length width.
`count`	Return the number of non-overlapping occurrences of substring sub in string S[start:end].
`encode`	Encode S using the codec registered for encoding.
`endswith`	Return True if S ends with the specified suffix, False otherwise.
`expandtabs`	Return a copy of S where all tab characters are expanded using spaces.
`find`	Return the lowest index in S where substring sub is found, such that sub is contained within S[start:end].
`format`	Return a formatted version of S, using substitutions from args and kwargs.
`format_map`	Return a formatted version of S, using substitutions from mapping.
`index`	Like S.find() but raise ValueError when the substring is not found.
`isalnum`	Return True if all characters in S are alphanumeric and there is at least one character in S, False otherwise.
`isalpha`	Return True if all characters in S are alphabetic and there is at least one character in S, False otherwise.
`isdecimal`	Return True if there are only decimal characters in S, False otherwise.
`isdigit`	Return True if all characters in S are digits and there is at least one character in S, False otherwise.
`isidentifier`	Return True if S is a valid identifier according to the language definition.
`islower`	Return True if all cased characters in S are lowercase and there is at least one cased character in S, False otherwise.
`isnumeric`	Return True if there are only numeric characters in S, False otherwise.
`isprintable`	Return True if all characters in S are considered printable in repr() or S is empty, False otherwise.
`isspace`	Return True if all characters in S are whitespace and there is at least one character in S, False otherwise.
`istitle`	Return True if S is a titlecased string and there is at least one character in S, i.e.
`isupper`	Return True if all cased characters in S are uppercase and there is at least one cased character in S, False otherwise.
`join`	Return a string which is the concatenation of the strings in the iterable.
`ljust`	Return S left-justified in a Unicode string of length width.
`lower`	Return a copy of the string S converted to lowercase.
`lstrip`	Return a copy of the string S with leading whitespace removed.
`maketrans`	Return a translation table usable for str.translate().
`partition`	Search for the separator sep in S, and return the part before it, the separator itself, and the part after it.
`replace`	Return a copy of S 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`	Like S.rfind() but raise ValueError when the substring is not found.
`rjust`	Return S right-justified in a string of length width.
`rpartition`	Search for the separator sep in S, starting at the end of S, and return the part before it, the separator itself, and the part after it.
`rsplit`	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.
`rstrip`	Return a copy of the string S with trailing whitespace removed.
`split`	Return a list of the words in S, using sep as the delimiter string.
`splitlines`	Return a list of the lines in S, breaking at line boundaries.
`startswith`	Return True if S starts with the specified prefix, False otherwise.
`strip`	Return a copy of the string S with leading and trailing whitespace removed.
`swapcase`	Return a copy of S with uppercase characters converted to lowercase and vice versa.
`title`	Return a titlecased version of S, i.e.
`translate`	Return a copy of the string S in which each character has been mapped through the given translation table.
`upper`	Return a copy of S converted to uppercase.
`zfill`	Pad a numeric string S with zeros on the left, to fill a field of the specified width.
