I know that this sounds trivial, but I did not realize that the sort() function of Python was weird. I have a list of "numbers" that are actually in string form, so I first convert them to ints, then attempt a sort.

Oct 5, 2013 · And the sort method has a parameter, called key, which you can pass a function. Using this parameter, your list won't be ordered by the values of the list, but by the values of your function on the list. In your case, you should use the abs () function, which will return the absolute value of your list elements. So, your list

Dec 4, 2012 · If you want to return the complete list in sorted order, this may work. This takes your input list and runs sorted on top of it. The reverse argument set to True sorts the list in reverse (descending) order, and the key argument specifies the method by which to sort, which in this case is the float of the third argument of each list:

Oct 10, 2023 · I'm fairly new to programming; I've only been studying Python for a few weeks. I've been given an exercise recently that asks me to generate a list of integers, and then manually sort the numbers from lowest to highest in a separate list.

Jul 31, 2023 · I have tried to figure this out in different ways, without any success. I keep getting an ascending order sort, rather than descending order when I print. ListB = [24, 13, -15, -36, 8, 22, 48, 25,...

Oct 29, 2013 · That looks like your list doesn't contain any numbers but strings. Python doesn't try to guess what might be inside of those strings, so you get an odd sort order.

There's also distutils.version.LooseVersion which is a little more forgiving with version numbers that end in letters ['1.0b', '1.0.2-final'], etc. or whatnot - I prefer this version since StrictVersion seems to be more oriented towards Python distutils specific version strings, LooseVersion caters to a wider swath of potential version strings you'll see in the wild.

I'm processing some files in a directory and need the files to be sorted numerically. I found some examples on sorting—specifically with using the lambda pattern—at wiki.python.org, and I put this

while data_list: new_list.append(heapq.heappop(data_list))) I suggest having a look in the Python library for heapq.py to see how it works. Heapsort is quite a fun sorting algorithm as it lets you 'sort' an infinite stream, i.e. you can quickly get at the currently smallest item but also efficiently add new items to the the data to be sorted.

Dec 19, 2012 · What is the fastest way to sort an array of whole integers bigger than 0 and less than 100000 in Python? But not using the built in functions like sort. Im looking at the possibility to combine 2 sport functions depending on input size.
