Question

I have a program which reads commands from a text file

for example, the command syntax will be as follows and is a string

'index command param1 param2 param3'

The number of parameters is variable from 0 up to 3
index is an integer
command is a string
all the params are integers

I would like to split them so that I have a list as follows

[index,'command',params[]]

What is the best way to do this?

Thanks

Not sure if it’s the best way, but here’s one way:

lines = open('file.txt')
for line in lines:
   as_list = line.split()
   result = [as_list[0], as_list[1], as_list[2:]]
   print result

Result will contain

['index', 'command', ['param1', 'param2', 'param3']]
