Random "programming language"

I decided to write my own programming language, of sorts. Essentially, you write code into a text file and the program will run the code inside the text file. The file is provided through a script argument.

```
# Basic programming language
from operator import eq, ne, lt, gt, le, ge
from random import random
from sys import exit, argv

# Specify file to be run
code = argv([1])

"""
>> - Specify to the user that something will be outputted.
=": ge,
"": gt
}

# Dict storing program data
data = {
"vars": [0] * 100000,
"rand": random()
}

# Interpret the code
def interpreter(separator):
for line in open(code, "r").readlines():

# Split each line
s_command = line.split(separator)

# Basic input and output
if s_command[0] == "$out" and s_command[1] == ">>":
if s_command[2] in data:
print data[s_command[2]]
if s_command[2] not in data:
print s_command[2]
if s_command[0] == "$inp" and s_command[1] == ">":
print data["vars"][int(s_command[2])]

# Test integer values
if s_command[0] == "$testint" and s_command[1] == ">>":
if s_command[3] in OPERATORS:
print OPERATORS[s_command[3]](
int(s_command[2]),
int(s_command[4]))

# Test string values
if s_command[0] == "$teststr" and s_command[1] == ">>":
if s_command[3] in OPERATORS:
print OPERATORS[s_command[3]](
s_command[2],
s_command[4])

# Test variable values
if s_command[0] == "$testvar" and s_command[1] == ">>":
if s_command[3] in OPERATORS:
print OPERATORS[s_command[3]](
data["vars"][int(s_command[2])],
data["vars"][int(s_command[4])])

# Terminate the program
if s_command[0] == "$exit" and s_command[1] == ">>":
exit(int(s_comm

It looks like all your tests follow the pattern

if s_command[0] == "$xxxxx" and s_command[1] == "yyyyy":

So what you can do is create a tuple of the first two elements of s_command:

instr = tuple(s_command[:2])

Then, you can do

if instr == ("$xxxxx", "yyyyy"):

Next, you can use a dictionary to collect all your instructions in one place:

Instructions = {
    ("$out", ">>"): do_out,
    ("$inp", "<<"): do_inp,
    ("$assignint", "<<"): do_assignint,
    ...
}

Then you would define a number of functions, one for each instruction, such as

def do_inp(s_command):
    inp = raw_input(s_command[2])

and call your methods with

Instructions[instr](s_command)
