What does "'module' object is not subscriptable" mean in the context of this code?

Running test.py gives

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    Map = Parser.Map(os.path[0] + "\\start.wmap")
TypeError: 'module' object is not subscriptable

Parser.py

import configparser
def StringIsNumber(String):
    try:
        int(String)
    except:
        return False
    return True
class Map:
    Parser = configparser.RawConfigParser()
    MapURL = ""
    def __init__(self, Map):
        self.Parser.read(Map)
        se开发者_StackOverflow中文版lf.MapURL = Map
    def TileTypes(self):
        #All numerical sections can be assumed to be tiles
        return [n for n in self.Parser.sections() if StringIsNumber(n)]

test.py

import Parser
import os
Map = Parser.Map(os.path[0] + "\\start.wmap")
print(Map.TileTypes())

os.path is a module and you are using it as a list i think you're looking for sys.path.

That you can't get its properties using key/index lookup like something[property]

You try to subscript os.path, which is a module. Subscripting means you use square brackets upon an object. That is legal for e.g. a dict object, but not for a module.

The error is in os.path[...]

os.path is a module. It's unclear what you think os.path[0] is going to do for you, since it's not an iterable and has no 0th element.
