如何从另一个python文件中获取函数参数
我在Python中有三个文件，称为A.Py，B.Py和C.Py 我想使用以下代码段做点什么，以确定
if __name__ == "__main__":
subprocess.Popen('python A.py', shell=True).wait()
subprocess.Popen('python C.py', shell=True)
程序运行时的执行顺序（我从b.py内运行程序），它等待A.Py的响应以接收Reciv_func中的值（a，a，,, a， b，c）函数，可能需要一些时间才能使A.Py接收结果，所以我等到第一次运行A.Py
我的问题是在B.Py文件中我可以访问值reciv_func（a，， b，c）在功能中，但我在外面无法访问它们，我甚至在全球范围内定义了
。
async def main():
url = f'my_url'
async with websockets.connect(url) as client:
while True:
data = json.loads(await client.recv())['data']
B.reciv_func(data['x']['y']['z'])
if __name__ == "__main__":
asyncio.run(main())
变量
reciv_func(a,b,c):
global a1
global b2
global c3
a1 = a
b2 = b
c3 = c
# out of reciv_func no access to a1 , b2 , c3
I have three files in Python called A.py, B.py and C.py
I wanted to do something with the following code snippet to determine the execution order (I run the program from within B.py)
if __name__ == "__main__":
subprocess.Popen('python A.py', shell=True).wait()
subprocess.Popen('python C.py', shell=True)
When the program runs, it waits for a response from A.py to receive the values in the reciv_func (a, b, c) function, it may take some time for A.py to receive the results, so I wait until the first Run A.py
My problem is that in the B.py file I have access to the values reciv_func (a, b, c) in the function but I have no access to them outside I have even defined the variables globally
A.py
async def main():
url = f'my_url'
async with websockets.connect(url) as client:
while True:
data = json.loads(await client.recv())['data']
B.reciv_func(data['x']['y']['z'])
if __name__ == "__main__":
asyncio.run(main())
B.py
reciv_func(a,b,c):
global a1
global b2
global c3
a1 = a
b2 = b
c3 = c
# out of reciv_func no access to a1 , b2 , c3

如果要访问 a1，b2，c3 在 a.py 中访问函数后：
b.reciv_func（data ['x''] ['y y y '] ['z']）最简单的方法是使用返回，而无需任何全局变量。例如，如果您编辑 b.py as：
可以在调用函数时返回所需的变量：
这样，您可以访问对应于 a1，b2，c3 <的值/em>按照您的意愿 a.py 。
If you want to access a1,b2,c3 in your A.py after calling the function:
B.reciv_func(data['x']['y']['z'])The easiest way is to use return, without the need for any global variables. For example, if you edit B.py as:
You can return the desired variables when you call the function:
In this way, you can access the values corresponding to a1,b2,c3 as you wish within A.py.
