If all buttons work the same you can treat them uniformly:
import gtk
command_defs = {
"uname" : ['uname'],
"ls" : ['cd /home/myUserId/Images/EarlGray',
'ls *.jpg']
}
class MyProgram:
def __init__(self):
...
for name, command in command_defs.iteritems():
button = gtk.Button(name)
button.connect("clicked", self.print_associated_command,
command)
button.show()
...
...
def print_associated_command(self, widget, data=None):
for item in data:
print 'COMMAND:', item
print '-----------------------------------------------------'
You can then move the command_defs dictionary into another module or
alternatively turn it into a JSON file and load it with the json module from
the standard library:
import json
with open("command_defs.json") as f:
command_defs = json.load(f)
The corresponding JSON file would then look like
{
"uname" : ["uname"],
"ls" : ["cd /home/myUserId/Images/EarlGray",
"ls *.jpg"]
}
Note that with this approach all strings become unicode objects.
