Module contents¶
Compatability modules… at the moment, this only contains the ordered dict backport that’s posted to active state
-
class
viscid.compat.
OrderedDict
(**kwds)[source]¶ Bases:
dict
Dictionary that remembers insertion order
-
classmethod
fromkeys
(S[, v]) → New ordered dictionary with keys from S.[source]¶ If not specified, the value defaults to None.
-
pop
(k[, d]) → v, remove specified key and return the corresponding[source]¶ value. If key is not found, d is returned if given, otherwise KeyError is raised.
-
popitem
() → (k, v), return and remove a (key, value) pair.[source]¶ Pairs are returned in LIFO order if last is true or FIFO order if false.
-
update
([E, ]**F) → None. Update D from mapping/iterable E and F.¶ If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

izip
¶ Bases:
object
izip(iter1 [,iter2 […]]) –> izip object
Return a izip object whose .next() method returns a tuple where the i-th element comes from the i-th iterable argument. The .next() method continues until the shortest iterable in the argument sequence is exhausted and then it raises StopIteration. Works like the zip() function but consumes less memory by returning an iterator instead of a list.

izip_longest
¶ Bases:
object
izip_longest(iter1 [,iter2 […]], [fillvalue=None]) –> izip_longest object
Return an izip_longest object whose .next() method returns a tuple where the i-th element comes from the i-th iterable argument. The .next() method continues until the longest iterable in the argument sequence is exhausted and then it raises StopIteration. When the shorter iterables are exhausted, the fillvalue is substituted in their place. The fillvalue defaults to None or can be specified by a keyword argument.

unicode
(object='') → unicode object¶ Bases:
basestring
unicode(string[, encoding[, errors]]) -> unicode object
Create a new Unicode object from the given encoded string. encoding defaults to the current default string encoding. errors can be ‘strict’, ‘replace’ or ‘ignore’ and defaults to ‘strict’.
-
capitalize
() → unicode¶ Return a capitalized version of S, i.e. make the first character have upper case and the rest lower case.
-
center
(width[, fillchar]) → unicode¶ Return S centered in a Unicode string of length width. Padding is done using the specified fill character (default is a space)
-
count
(sub[, start[, end]]) → int¶ Return the number of non-overlapping occurrences of substring sub in Unicode string S[start:end]. Optional arguments start and end are interpreted as in slice notation.
-
decode
([encoding[, errors]]) → string or unicode¶ 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.
-
encode
([encoding[, errors]]) → string or unicode¶ 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 can handle UnicodeEncodeErrors.
-
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.
-
expandtabs
([tabsize]) → unicode¶ 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.
-
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.
-
format
(*args, **kwargs) → unicode¶ Return a formatted version of S, using substitutions from args and kwargs. The substitutions are identified by braces (‘{‘ and ‘}’).
-
index
(sub[, start[, end]]) → int¶ Like S.find() but raise ValueError when the substring is not found.
-
isalnum
() → bool¶ Return True if all characters in S are alphanumeric and there is at least one character in S, False otherwise.
-
isalpha
() → bool¶ Return True if all characters in S are alphabetic and there is at least one character in S, False otherwise.
-
isdecimal
() → bool¶ Return True if there are only decimal characters in S, False otherwise.
-
isdigit
() → bool¶ Return True if all characters in S are digits and there is at least one character in S, False otherwise.
-
islower
() → bool¶ Return True if all cased characters in S are lowercase and there is at least one cased character in S, False otherwise.
-
isnumeric
() → bool¶ Return True if there are only numeric characters in S, False otherwise.
-
isspace
() → bool¶ Return True if all characters in S are whitespace and there is at least one character in S, False otherwise.
-
istitle
() → bool¶ Return True if S is a titlecased string and there is at least one character in S, i.e. upper- and titlecase characters may only follow uncased characters and lowercase characters only cased ones. Return False otherwise.
-
isupper
() → bool¶ Return True if all cased characters in S are uppercase and there is at least one cased character in S, False otherwise.
-
join
(iterable) → unicode¶ Return a string which is the concatenation of the strings in the iterable. The separator between elements is S.
-
ljust
(width[, fillchar]) → int¶ Return S left-justified in a Unicode string of length width. Padding is done using the specified fill character (default is a space).
-
lower
() → unicode¶ Return a copy of the string S converted to lowercase.
-
lstrip
([chars]) → unicode¶ Return a copy of the string S with leading whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is a str, it will be converted to unicode before stripping
-
partition
(sep) -> (head, sep, tail)¶ Search for the separator sep in S, and return the part before it, the separator itself, and the part after it. If the separator is not found, return S and two empty strings.
-
replace
(old, new[, count]) → unicode¶ Return a copy of S with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced.
-
rfind
(sub[, start[, end]]) → int¶ Return the highest 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.
-
rindex
(sub[, start[, end]]) → int¶ Like S.rfind() but raise ValueError when the substring is not found.
-
rjust
(width[, fillchar]) → unicode¶ Return S right-justified in a Unicode string of length width. Padding is done using the specified fill character (default is a space).
-
rpartition
(sep) -> (head, sep, tail)¶ 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. If the separator is not found, return two empty strings and S.
-
rsplit
([sep[, maxsplit]]) → list of strings¶ 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. If maxsplit is given, at most maxsplit splits are done. If sep is not specified, any whitespace string is a separator.
-
rstrip
([chars]) → unicode¶ Return a copy of the string S with trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is a str, it will be converted to unicode before stripping
-
split
([sep[, maxsplit]]) → list of strings¶ Return a list of the words in S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result.
-
splitlines
(keepends=False) → list of strings¶ Return a list of the lines in S, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.
-
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.
-
strip

() → unicode¶ Return a titlecased version of S, i.e. words start with title case characters, all remaining cased characters have lower case.
-
translate
(table) → unicode¶ Return a copy of the string S, where all characters have been mapped through the given translation table, which must be a mapping of Unicode ordinals to Unicode ordinals, Unicode strings or None. Unmapped characters are left untouched. Characters mapped to None are deleted.
-
upper
() → unicode¶ Return a copy of S converted to uppercase.
-
zfill
(width) → unicode¶ Pad a numeric string S with zeros on the left, to fill a field of the specified width. The string S is never truncated.
