Yield all items in an iterable collection that are distinct.
Unlike when using sets for a similar effect, the original ordering of the
items in the collection is preserved by this function.
>>> print list(distinct([1, 2, 1, 3, 4, 4]))
[1, 2, 3, 4]
>>> print list(distinct('foobar'))
['f', 'o', 'b', 'a', 'r']
- Parameters:
iterable - the iterable collection providing the data - Returns: iterator
- the distinct items in the collection
|
pathmatch(pattern,
filename)
|
|
Extended pathname pattern matching.
This function is similar to what is provided by the fnmatch module in
the Python standard library, but:
- can match complete (relative or absolute) path names, and not just file
names, and
- also supports a convenience pattern ("**") to match files at any
directory level.
Examples:
>>> pathmatch('**.py', 'bar.py')
True
>>> pathmatch('**.py', 'foo/bar/baz.py')
True
>>> pathmatch('**.py', 'templates/index.html')
False
>>> pathmatch('**/templates/*.html', 'templates/index.html')
True
>>> pathmatch('**/templates/*.html', 'templates/foo/bar.html')
False
- Parameters:
pattern - the glob patternfilename - the path name of the file to match against - Returns:
bool
True if the path name matches the pattern, False otherwise
|
wraptext(text,
width=70,
initial_indent='',
subsequent_indent='')
|
|
Simple wrapper around the textwrap.wrap function in the standard
library. This version does not wrap lines on hyphens in words.
- Parameters:
text - the text to wrapwidth - the maximum line widthinitial_indent - string that will be prepended to the first line of
wrapped outputsubsequent_indent - string that will be prepended to all lines save
the first of wrapped output - Returns:
list
- a list of lines
