Hi there everyone,

Does anyone have a clue on an ideal function body for this script so that it will pass the doctest?

def sortstuff(mylist):
"""
>>> sortstuff([3, 5, 1, 9, 13, 2])
[1, 2, 3, 5, 9, 13]
>>> sortstuff(["one", "two", "three", "four"])
['four', 'one', 'three', 'two']
"""
 
# Function body will go here
 
if __name__ == '__main__':
import doctest
doctest.testmod(verbose=True)

Cheers!

Should you not use Python sort? For example:

li=[1,9,2,3];
li.sort();
print li;

Note that sort is a method, and the list is changed in place.

Suppose you have a matrix, and you want to sort by second column. Example Solution:

li=[[2,6],[1,3],[5,4]]
li.sort(lambda x, y: cmp(x[1],y[1]))
print li; # prints [[1, 3], [5, 4], [2, 6]]

  • You can enable syntax highlighting of source code with the following tags: <code>, <blockcode>, <c>, <cpp>, <drupal5>, <drupal6>, <java>, <javascript>, <php>, <python>, <ruby>. Beside the tag style "<foo>" it is also possible to use "[foo]". PHP source code can also be enclosed in <?php ... ?> or <% ... %>.
