Need basic help with Python file output

[TheShader]

Hello, I have a little experience about programming. I want to make a configuration file generator with python. I'm thinking of making it like this:

input the variables
open the file
file.write('{some code%d}\n{some code%d}...' %var1 %var2 ...)

But is there a way of defining the variables in a text file, and making Python find and replace them? Which one is better? Is there a better, or easier way of doing this? Thanks :popcorn:

I have been teaching myself python. I use geany & glade also. In glade I need the buttons to add to my python code so I wrote a simple parser to find then & output in a format I could directly paste into my code.

This parses a glade file for buttons and outputs a test file. I have only run it from geany so I am not even sure it works on its own yet.


#!/usr/bin/env python
# -*- coding: utf-8 -*-

import re, csv

try:
filename = "test.py"
ifile = open(filename, "w")
except IOError:
Return

def main():
datafile = file('main.glade')
#!/usr/bin/env python
# -*- coding: utf-8 -*-

for line in datafile:
#a = re.search('object class="GtkButton".*?id="(.*?)">', line)
a = re.search('object class=.*?id="(.*?)">', line)
if a:
quote = a.group(1)
#self.btn_go = self.builder.get_object("btn_go")
#print 'self.' + quote +' = self.builder.get_object("' + quote + '")'
text1 = 'self.' + quote +' = self.builder.get_object("' + quote + '")\n'
ifile.write(text1)

datafile = file('main.glade')
for line in datafile:
m = re.search('signal name="clicked".*?handler="(.*?)"/>', line)
if m:
quote = m.group(1).strip()
#def on_btn_forward_clicked(self, btn):
#print 'def ' + quote + '(self, btn):'
#print ' pass'
text2 = 'def ' + quote + '(self, btn):\n'
text3 = ' pass\n'
ifile.write(text2)
ifile.write(text3)

def closefile():
ifile.close()

if __name__ == "__main__":
# Someone is launching this directly
main()

Not sure I understand exactly what you are trying to do. If you're going for a 'hand-editable' config file, something that looks like:

item1=parameter
item2=parameter
# This is a comment
item3=parameter

Then you could use dictionaries and a split to store and to write them. I've done similar things many times.



config_dict={}
config_file=open('/path/to/config_file, 'r')
for line in config_file:
if line[0] != "#":
item, val=line.split("=")
config_dict[item]=val
config_file.close()


or do it all with a generator:


config_dict=dict([line.split("=") for line in config_file where line[0] != "#" and line[0] != "\n"])

Just do the opposite for the writes.

Thanks for advices ^^ I've made it a little different, since I had to make it all line-by line. It's very very basic, you can check it. It helps you to generate a server.cfg file for Counter-Strike: Source dedicated server on the Linux command line. It's in Turkish, wrote it for my tutorial for setting up a server ;)
