NameError: name 'pandas' is not defined 当我调用本地函数时

Question

我正在尝试将一些本地函数导入到我的主程序中，如下所示：

class QuestionManager: ObservableObject {
    @Published var question: Question
    @Published var type: Question.QuestionType
    @Published var prompt: String
    @Published var options: [String]?
    @Published var error: String? = nil
    @Published var id = ""
    
    init(_ question: Question) {
        self.question = question
        self.type = question.type
        self.prompt = question.prompt
        self.options = question.options
        self.id = question.id
    }
    
    func saveQuestion() {
        self.question.prompt = prompt
        self.question.type = type
        self.question.options = options
    }
    
    func checkQuestion() -> Bool {
        if type == .checkbox || type == .multiple {
            if options!.count < 2 {
                error = "You must have at least two options"
                return false
            }
            else if options!.contains("") {
                error = "Options must not be empty"
                return false
            }
            else if !options!.elementsAreUnique() {
                error = "Options must be unique"
                return false
            }
        }
        if prompt.isEmpty {
            error = "You must include a prompt for your question"
            return false
        }
        return true
    }
    
    func changeType(_ type: Question.QuestionType) {
        if type == .text {
            options = nil
        }
        else {
            options = ["Option 1", "Option 2", "Option 3"]
        }
        self.type = type
    }
    
    func addOption() {
        guard options != nil else { return }
        if options!.count == 5 {
            error = "No more than 5 options are permitted"
        }
        else {
            let count = options!.count
            let newOption = "Option \(count + 1)"
            options!.append(newOption)
        }
    }
    
    func deleteOption(option: String) {
        guard options != nil else { return }
        guard let index = self.options!.firstIndex(of: option) else {
            self.error = "An error occured during deleting ... sorry you're screwed"
            return
        }
        self.options!.remove(at: index)
    }
}

函数“funciones.py”是下一个：

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from funciones import dumifica

df_orig = pd.read_csv("D:/BMA_TBL_CONSOLIDADO_PYME_FULL_C1_DEV.csv",';')
df_all = df_orig[[a for a in df_orig.columns if a in ('ID_ANO_MES','ID_RUT','CLAS_VAR11','CLAS_VAR9','TIPO_DEU_SBIF_CMF','TIPO_DEU_SBIF12_CMF','TIPO_DEU_SBIF3_CMF','TIPO_DEU_SBIF6_CMF','tip_deudor_12_CMF')]]
df_orig.head()
vars_dum = ['CLAS_VAR11','CLAS_VAR9']
    for i in vars_dum:
        df_all = dumifica(df_all,i)

程序显示了下一个错误：

NameError: name 'pandas' 未定义

PS：该程序在我将函数包含在同一代码中时没有问题，当我尝试执行外部代码时会出现问题。
