我正在尝试将具有文件名/位置的变量从一个Python文件传递到Python 3.6.8上的另一个文件。
我尝试了以下代码,但是它不起作用:
executor.py(此文件是第一个文件,由用户运行),我输入code.ntx,因为这是我要使用的文件[我不需要放C :\东西,因为我的文件与executor.py在同一文件夹中:
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('#'):
当我运行该executor.py并用code.ntx填写输入时,出现以下错误:
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

不要这样做。构建一个真实的界面并导入它,不要使用import
运行可执行脚本。
# executor.py
filename = input("...")
import nitrix001
nitrix001.main(filename)
# nitrix001
def main(filename):
with open(filename) as f:
for line in f:
# do stuff

@威廉
我不知道您要达到的目标。我会改用功能
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nitroix001.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('#'):

这通常不是在文件之间传递变量的好习惯,实际上,您要尝试的是窃取__main__
的全局变量,因此与传递的相反,而且您会获得所有变量,而不是只是文件名。
您应该做的是将第二个文件导入第一个脚本的顶部。在第二个文件中,有一个函数,该函数带有您要传入的参数。然后,您可以从主脚本中调用该函数。
executor.py
import nitrix001
filename = input('What file would you like to open? ')
print('Loading ' + filename + '...')
nitrix001.run(filename)
nitrix001.py
def run(filename):
#do work with the file
