basically, i was in school, and i got bored and was like "what if python used include instead of import?" so i made this

includes.py

import os
import tempfile
import subprocess

filename = "test.py"
alreadyincluded = []

with open(filename) as f:
    fullfile = f.read()
    filesplitlines = fullfile.splitlines()
    
newfile = ""


newsplitlines = []

for line in filesplitlines:
    newsplitlines.append(line)
    try:
        if line.split()[0] == "#include":
            filetoinclude = line.split()[1]
            with open(filetoinclude) as f:
                filecontents = f.read()
                if not (filetoinclude in alreadyincluded):
                    newsplitlines.append(filecontents)
                
                try:
                    
                    if filecontents.splitlines()[0] == "#pragma once":
                        alreadyincluded.append(filetoinclude)
                except:
                    pass
                
    except:
        pass

realcode = ""

for line in newsplitlines:
    realcode += line + "\n"
    
with tempfile.TemporaryDirectory() as tmpdir:
    tmppyfile = os.path.join(tmpdir, "temp.py")
    
    with open(tmppyfile, "w") as py:
        py.write(realcode)
    
    subprocess.call(["python", tmppyfile])
