Miscellaneous modules for translate - including modules for backward compatibility with pre-2.3 versions of Python
Implements a case-insensitive (on keys) dictionary and order-sensitive dictionary
translate.misc.dictutils.cidict(fromdict=None)¶clear() → None. Remove all items from D.¶copy() → a shallow copy of D¶fromkeys()¶Create a new dictionary with keys from iterable and values set to value.
get(key, default=None)¶Return the value for key if key is in the dictionary, else default.
items() → a set-like object providing a view on D's items¶keys() → a set-like object providing a view on D's keys¶pop(k[, d]) → v, remove specified key and return the corresponding value.¶If key is not found, d is returned if given, otherwise KeyError is raised
popitem() → (k, v), remove and return some (key, value) pair as a¶2-tuple; but raise KeyError if D is empty.
setdefault()¶Insert key with a value of default if key is not in the dictionary.
Return the value for key if key is in the dictionary, else default.
update(E) → None.¶Update D from E: for k in E.keys(): D[k] = E[k]
values() → an object providing a view on D's values¶Supports a hybrid Unicode string that can also have a list of alternate strings in the strings attribute

maketrans()¶Return a translation table usable for str.translate().
If there is only one argument, it must be a dictionary mapping Unicode ordinals (integers) or characters to Unicode ordinals, strings or None. Character keys will be then converted to ordinals. If there are two arguments, they must be strings of equal length, and in the resulting dictionary, each character in x will be mapped to the character at the same position in y. If there is a third argument, it must be a string, whose characters will be mapped to None in the result.
partition()¶Partition the string into three parts using the given separator.

Raises ValueError when the substring is not found.
rjust()¶Return a right-justified string of length width.
Padding is done using the specified fill character (default is a space).
rpartition()¶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.

translate()¶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.
upper()¶Return a copy of the string converted to uppercase.
zfill()¶Pad a numeric string with zeros on the left, to fill a field of the given width.
The string is never truncated.

disable_interspersed_args()¶Set parsing to stop on the first non-option. Use this if you have a command processor which runs another command that has options of its own and you want to make sure these options don’t get confused.
enable_interspersed_args()¶Set parsing to not stop on the first non-option, allowing interspersing switches with command arguments. This is the default behavior. See also disable_interspersed_args() and the class documentation description of the attribute allow_interspersed_args.
