如何将变量从一个Python脚本传递到另一个Python脚本？

Question

在Python 3.6.8上，我试图将一个带有文件名/位置的变量从一个Python文件传递到另一个Python文件。

我尝试了以下代码，但不起作用：

你知道吗执行人.py（此文件是我输入的第一个文件，由用户运行）代码.ntx因为这就是我想要使用的文件[我不需要把C:\的东西放在同一个文件夹中，因为我的文件和执行人.py]地址：

print('What file would you like to open? (ex. C:\\Users\\JohnDoe\\Documents\\helloworld.ntx): ')
filename = input()
print('Loading ' + filename + '...')

import nitrix001

nitrix001.py代码（以及与此相关的部分）

from __main__ import *

if filename == " ":
    # The user can set this to the name of the file.
    filename = "lang.ntx"
# Opens the actual file. We use this in the 'for' loop.
File = open(f"{filename}", "r")
#
Characters = ''
# Integer that indicates the line of the program the language is reading.
Line = 1
# Variable that checks if the program is currently inside parantheses.
args = False

# Runs a 'for' loop on each line of the file.
for LineData in File:
    print(f'\nRunning Line {Line}: {LineData}')
    if not LineData.startswith('#'):

当我运行时执行人.py并在输入中填入代码.ntx我得到以下错误：

Traceback (most recent call last):
  File "main.py", line 1, in <module>
    import executor
  File "/home/runner/executor.py", line 16, in <module>
    import nitrix001
  File "/home/runner/nitrix001.py", line 3, in <module>
    if filename == " ":
NameError: name 'filename' is not defined

我不知道怎样才能达到你的目的。我会用函数代替

print('What file would you like to open? (ex. C:\\Users\\JohnDoe\\Documents\\helloworld.ntx): ')
filename = input()
print('Loading ' + filename + '...')

from nitrix001 import myfunc
myfunc(filename)

然后在nitrix001.py上：

def myfunc(filename)
    if filename == " ":
        # The user can set this to the name of the file.
        filename = "lang.ntx"
    # Opens the actual file. We use this in the 'for' loop.
    File = open(f"{filename}", "r")
    #
    Characters = ''
    # Integer that indicates the line of the program the language is reading.
    Line = 1
    # Variable that checks if the program is currently inside parantheses.
    args = False

    # Runs a 'for' loop on each line of the file.
    for LineData in File:
        print(f'\nRunning Line {Line}: {LineData}')
        if not LineData.startswith('#'):
