How to get float text file in python?

Question

I have a textfile .txt with the following structure:

a-011bbbad022b7889c
a-0cf9f08ade83aed64
a-0408c0e6745bc2563
a-074b8709a7e4c9751
a-0d083d670fd0587a9
a-0670147fdd4dfec3a
a-075429f00fe0cf19a
a-0b734cd1f480a2f3c
a-0d1422812bc7344f1
a-092b72359be9b447b

What is the easiest way to get data into an array?

Have you done any effort to at least learn how to read the file within python? — Niel Godfrey Pablo Ponciano, Sep 07 '21 at 13:25

import struct
output_arr = []
with open('somefile.txt', 'r') as f:
    for line in f:
        float_num = struct.unpack('!f', bytes.fromhex(line.split('a-')[1]))[0]
        output_arr.append(float_num)

I don't see where the question specified the data needed parsed – OneCricketeer Sep 07 '21 at 13:33
It was specifically asked how to get the text as float. – BTables Sep 07 '21 at 13:36
it's not clear how do you want to convert the values. Are they in hexadecimal? byte representation or whatever? – Paolopast Sep 07 '21 at 14:54
@Paolopast I'm not sure what's unclear about the conversion. `bytes.fromhex` is a built in type and only has one function. – BTables Sep 07 '21 at 15:03
There are better ways to remove the prefix then using `line.split('a-')` – mousetail Sep 08 '21 at 13:38

As stated in the comments, you can do this in just one line:

result = open("test.txt").read().splitlines()

Open and read

A .txt file can be opened and read like this:

with open(r"C:\\Path\to\file.txt", 'r') as file:
    content = file.read()

Split

Then, you can get the lines like this:

content = content.splitlines()

You can use readlines directly from the file – OneCricketeer Sep 07 '21 at 13:33
Right, I saw the other's explaination so I tought that more than a line of code would have been more usefull to them to understand. – FLAK-ZOSO Sep 07 '21 at 13:37
