如何使用一个工作簿中的列，遍历另一个工作簿并复制相应的数据

Question

I have two excel workbooks. One is a list of names (10-15k) in column A and 1-3 digit number in column B. The second only has a list of names in column A. I want to upload both files then iter the names from workbook2 through workbook1 and receive workbook3 that would only have names that did not appear in workbook1 with a 0 in the next column over. I'm trying to do this with tkinter so it can be an executable program for some coworkers.

I'm pretty new at coding so I'm getting a bit lost. What I have so far is below and I'm sure there are mistakes:(

import tkinter as tk
from tkinter import filedialog
from tkinter import messagebox
import pandas as pd

root= tk.Tk()

canvas1 = tk.Canvas(root, width = 400, height = 300, bg = 'lightsteelblue2', relief = 'raised')
canvas1.pack()

label1 = tk.Label(root, text='Interaction Comparison', bg = 'lightsteelblue2')
label1.config(font=('bookman old style', 20))
canvas1.create_window(200, 40, window=label1)

def getCSV1 ():
    global read_file1

    import_file_path = filedialog.askopenfilename()
    read_file = pd.read_csv (import_file_path)

browseButton_CSV1 = tk.Button(text="      Import Interaction CSV File     ", command=getCSV1, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 110, window=browseButton_CSV1)

def getCSV2 ():
    global read_file2

    import_file_path = filedialog.askopenfilename()
    read_file = pd.read_csv (import_file_path)

browseButton_CSV2 = tk.Button(text="      Import Comparison CSV File     ", command=getCSV2, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 160, window=browseButton_CSV2)

def convertToCSV ():
    global read_file1, read_file2
    data = pd.read_csv
    for i in read_file1.data.iterrows(read_file2):
        print (i)



    export_file_path = filedialog.asksaveasfilename(defaultextension='.csv')
    read_file.to_csv (export_file_path, index = None, header=True)

saveAsButton_CSV = tk.Button(text='CSV Comparison', command=convertToCSV, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 210, window=saveAsButton_CSV)

def exitApplication():
    MsgBox = tk.messagebox.askquestion ('Exit Application','Are you sure you want to exit the application',icon = 'warning')
    if MsgBox == 'yes':
       root.destroy()

exitButton = tk.Button (root, text='       Exit Application     ',command=exitApplication, bg='brown', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 260, window=exitButton)

root.mainloop()

Figured out what my issue was. Thank you to Hietsh Kumar for the reference to the merge method!

import tkinter as tk
from tkinter import filedialog
from tkinter import messagebox
import pandas as pd

root= tk.Tk()

canvas1 = tk.Canvas(root, width = 400, height = 300, bg = 'lightsteelblue2', relief = 'raised')
canvas1.pack()

label1 = tk.Label(root, text='Interaction Comparison', bg = 'lightsteelblue2')
label1.config(font=('bookman old style', 20))
canvas1.create_window(200, 40, window=label1)

def getExcel1 ():
    global df1
    
    import_file_path = filedialog.askopenfilename()
    df1 = pd.read_excel (import_file_path)
    
browseButton_CSV1 = tk.Button(text="      Import Interaction Excel File     ", command=getExcel1, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 110, window=browseButton_CSV1)

def getExcel2 ():
    global df2
    
    import_file_path = filedialog.askopenfilename()
    df2 = pd.read_excel (import_file_path)
    
browseButton_CSV2 = tk.Button(text="      Import Comparison Excel File     ", command=getExcel2, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 160, window=browseButton_CSV2)

def combinetoExcel ():
   
    df = pd.merge(df1,df2[['Alias','Interactions']], on = 'Alias', how = 'left')

    df.to_excel('List.xlsx', index = False)


saveAsButton_CSV = tk.Button(text='Excel List', command=combinetoExcel, bg='green', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 210, window=saveAsButton_CSV)

def exitApplication():
    MsgBox = tk.messagebox.askquestion ('Exit Application','Are you sure you want to exit the application',icon = 'warning')
    if MsgBox == 'yes':
       root.destroy()
     
exitButton = tk.Button (root, text='       Exit Application     ',command=exitApplication, bg='brown', fg='white', font=('bookman old style', 12, 'bold'))
canvas1.create_window(200, 260, window=exitButton)

root.mainloop()
