Python module execution not being procedural

Question

I am making a python module to edit a BrainFuck script and make it easy to program. (This is just for fun.) I have run into a problem where the functions are executing out of order and I have no idea how to fix it.

__init__.py:

#main
def init():
  f=open("main.bf","w")
  f.close
  f=open("BrainF/cell.txt","w")
  f.write("0")
  f.close

class cell:
  def goto(num):
    f=open("BrainF/cell.txt","r")
    current_cell=int(f.read())
    f.close
    y=current_cell-num
    if num >> current_cell:
      f=open("main.bf","a")
      x="a"*(num-current_cell)
      for i in x:
        f.write(">")
      f.close()
    if num << current_cell:
      f=open("main.bf","a")
      x="a"*abs(y)
      for i in x:
        f.write("<")
      f.close()
      
    f=open("BrainF/cell.txt","w")
    f.write(str(num))
    f.close
    
  def add(num):
    f=open("main.bf","a")
    x="a"*num
    for i in x:
      f.write("+")
    f.close()
    
  def subtract(num):
    f=open("main.bf","a")
    x="a"*num
    for i in x:
      f.write("-")
    f.close()

main.py:

import BrainF as bf

bf.init()
bf.cell.goto(2)
bf.cell.add(3)
bf.cell.goto(0)

file tree:

main.bf
main.py
BrainF
--__pycache__
--__init__.py
--cell.txt

When I run main.py with the command, python main.py it writes to main.bf. The problem is that it should execute in the correct order and main.bf would be >>+++<< but instead, it does not and the actual contents is >><<+++.

Is there any way to fix this so that the functions execute in order?

Answer 1

I fixed it. The problem was me not returning after finishing the function, and using >> instead of >. I fixed it and it works on the repl as well.

If you want, you can check in on the repl and use it as a easy python to BrainFuck translator!
