如何在主模块中连接输入和功能模块，我们可以从函数返回列表吗？

Question

I have three modules: GetInput, Main and Converter. In the GetInput file there are all the inputs values and excel data in the form of list. In the Converter file I am using those input values from Getinput file and in the main file I am connecting both these files here. I am doing this so that my code can look more organized. GetInput.py:

import pandas as pd
import numpy as np
import time

def getInputs():
    df = pd.read_excel('input.xlsx')
    actual = df['actual'].values.tolist()
    schedule = df['schedule'].values.tolist()
    freq = df['frequency'].values.tolist()
    ACP = df['acp'].values.tolist()


    modelInput = {
        'actual': actual, 'schedule': schedule, 'freq': freq, 'ACP': ACP,'df' : df
    }
    return modelInput

Converter.py

import pandas as pd
def fun(modelInput):
    underdraw = []
    overdraw = []
    for i,j, in zip(schedule, actual):
        dev = j - i
        if dev < 0:
            underdraw.append(dev)
        else:
            underdraw.append(0)

        if dev > 0:
            overdraw.append(dev)
        else:
            overdraw.append(0)

    df['underdraw'] = pd.Series(underdraw)
    df['overdraw'] = pd.Series(overdraw)
    df.to_excel('mainfile.xlsx')

Main.py

import pandas as pd
import numpy as np
from convert import *
from GetInputs import *

def fun1():
    inpu = getInputs()
    con = fun(inpu)
fun1()

This whole program works when I run it in a single module but it throw errors when I try divide my code into separate modules. Basically it throw error in GetInput.py and in Converter.py (df is not defined) file. I know its a very basic thing but I don't know how to make it work. There is no desired output for this program, I am already getting an output when I run it in a single file. I just want to divide my code in this format as I mentioned above: GetIput File, Converter File and Main File.

Answer 1

Keep all the files in same directory or else mention the file paths at the top of main code using os module.

You have misspelled the following in the main code:

from convert import *
from GetInputs import *

It should be:

from Converter import *
from GetInput import *

I have tested this using the following:

MainModule.py

from Converter import *
from GetInputs import *

def fun1():
    inpu = getInputs()
    con = fun(inpu)
fun1()

Converter.py

import pandas as pd
def fun(modelInput):
    print("HIE" + modelInput)

GetInputs.py

def getInputs():
    return "modelInput"
