Python TypeError:readData（）缺少1个必需的位置参数：'；数据'；

面临代码错误。我正处于python的学习阶段， 尝试使用selenium为Python创建DDT框架

userN = getData.readData(path,'Sheet1',r,1) TypeError: readData() missing 1 required positional argument: 'data'

下面是XLutil.py的代码

import openpyxl

class getData():


def getRowCount(file,sheetName):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    return (sheet.max_row)

def getColumnCount(file,sheetName):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    return (sheet.max_column)

def readData(file,sheetName,rownum,columnno):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    return sheet.cell(row=rownum,column=columnno).value

def writeData(file,sheetName,rownum,columnno,data):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    sheet.cell(row=rownum,column=columnno).value = data
    workbook.save(file)

下面是login.py的代码

        path = 'c:/Users/mahmood/PycharmProjects/Selenium_automaton/Login.xlsx'
    # global path
    driver = self.driver
    row = getData.getRowCount(path,'Sheet1')
    for r in range(2,row+1):
      driver.get("https://xxx-eee.xyxxxve.com/")
      userN = getData.readData(path,'Sheet1',r,1)
      passW = getData.readData(path,'Sheet1',r,2)

      login = LoginPage(driver)
      login.enter_username(userN)
      login.enter_password(passW)
      login.click_login()

      homepage = HomePage(driver)
      homepage.click_welcome()
      homepage.click_logout()

我正试图通过openpyxl从Excel工作表用户名和密码中获取数据

Python没有重载，没有第三方API也不行

他躲起来了

def readData(file, sheetName, rownum, columnno)

因此，当您尝试使用4个参数调用它时，会出现错误，因为

readData

需要5个参数。您可以改用默认值

def readData(file,sheetName,rownum,columnno, data=None):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    if data:
        sheet.cell(row=rownum,column=columnno).value = data
        workbook.save(file)
    else:
        return sheet.cell(row=rownum,column=columnno).value

请修复缩进，设置错误格式，并提供一个最小的、可复制的示例。这个问题与selenium无关，我们不需要查看整个代码库。

def readData(file,sheetName,rownum,columnno, data=None):
    workbook = openpyxl.load_workbook(file)
    sheet = workbook.get_sheet_by_name(sheetName)
    if data:
        sheet.cell(row=rownum,column=columnno).value = data
        workbook.save(file)
    else:
        return sheet.cell(row=rownum,column=columnno).value
