sorting - How do I sort columns of numerical file data in python

Question

I'm trying to write a piece of code in python to graph some data from a tab separated file with numerical data.

I'm very new to Python so I would appreciate it if any help could be dumbed down a little bit.

Basically, I have this file and I would like to take two columns from it, sort them each in ascending order, and then graph those sorted columns against each other.

Answer 1

First of all, you should not put code as images, since there is a functionality to insert and format here in the editor.

It's as simple as calling x.sort() and y.sort() since both of them are slices from data so that should work fine (assuming they are 1 dimensional arrays).

Here is an example:

import numpy as np
array = np.random.randint(0,100, size=50)
print(array)

Output:

[89 47 4 10 29 21 91 95 32 12 97 66 59 70 20 20 36 79 23 4]

So if we use the method mentioned before:

print(array.sort())

Output:

[ 4 4 10 12 20 20 21 23 29 32 36 47 59 66 70 79 89 91 95 97]

Easy as that :)
