Python

Hi, I must work with strings and i have this problem:

I have a file with variables like this.
a = 3234
b = 4545
c = 2343
d = 7653
e = 9237
f = 6545
g = 5697
h = 1248

I need a script that import this file and put it in rage of values.

Is there anyone who can help me?

Your exact needs are not clear enough. Do you just want those values to be sorted?

In fact, It's not so clear.

I just need to put in of increasing value

Well if your file is formatted EXACTLY like your example, you should be able to use this python script to give you what you need.

python sort_example.py.py input_file > output_file

You will need to make sure that ``sort_example.py`` and your file are in the same folder.


The contents of ``sort_example.py`` are:

import sys


in_file = sys.argv[1]

in_data = open(in_file, 'rU')

data_list = []

# separate and organize the data into fields
for line in in_data:
    data_list.append([x.strip() for x in line.strip('\n').split('=')])

# convert the number parts to actual numbers vs strings
for each in data_list:
    each[1] = float(each[1])


data_list.sort(key=lambda x: x[1])

for each in data_list:
    print '%s = %s' % (each[0],each[1])

or if you don't need to use Python you could always just do this...

sort -t ' ' -k3,3n myfile.txt
