Question

我正在制作一个excel比较程序，该程序需要一定数量的图纸，将它们进行比较并检查其中一张纸中的值是否在另一张纸中不存在。但是，我收到一个重复的问题。为了澄清，这是我的代码：

import tkinter as tk
from tkinter import filedialog
import openpyxl, os, csv
from openpyxl.utils import get_column_letter, column_index_from_string

# Output File
outputFile = open('output.csv','w',newline='')
outputWriter = csv.writer(outputFile)

# Tk initialization for file dialog
root = tk.Tk()
root.withdraw()

# Number of sheets to be compared
number = input('Enter number of workbook sheets for comparison: ')
number = int(number)

# Functions for generating file paths
def generate_file_path():
    file_path = filedialog.askopenfilename(title="Open Workbook")
    return file_path

# Variables to store file paths, workbooks and worksheets
all_ws = []

# Core function for program's logistics
def core():
    # for loops for generating file paths, workbooks and worsheets
    for x in range(number):
        path = generate_file_path()
        wb = openpyxl.load_workbook(path)
        ws = wb['CBF']
        all_ws.append(ws)

    # for loop to use for finding diff
    for row in all_ws[1].iter_cols():
        for cellz in row:
            sheet_cols.append(cellz.value)

    # loop that checks if the value does not exist
    for ws_diff in range(number):
        for row,row2 in zip(all_ws[0].iter_cols(),all_ws[1].iter_cols()):
            for cell,cell2 in zip(row,row2):
                if cell.value not in sheet_cols:
                    outputWriter.writerow([str(cell2.value)])

但是，当我检查csv文件时，输出的“差异”似乎同时出现在两个文件上。有人对我有什么建议吗？一切都很好，谢谢

Answer 1

也许您可以这样做：

更改：for row in all_ws[1].iter_cols():

收件人：for row in all_ws[0].iter_cols():
之后：

更改if cell.value not in sheet_cols:

收件人：if cell2.value in sheet_cols:

希望它会有所帮助：）

Answer 2

我试图尽可能地靠近您提供的源代码，仅保留了一些自由。我所做的最大更改是在csv输出中添加了更多列，并增加了告诉核心功能是否关心单元位置的功能；你是否-

1。）将第一个工作表之后的每个工作表的每个单元格与第一个工作表中的确切单元格坐标的值进行比较（location_matters = True）

还是您

2。）将第一个工作表之后的每个工作表的每个单元格与所选的第一个工作表中的每个值进行比较（location_matters = False）

这是我想出的修改后的代码：

import tkinter as tk
from tkinter import filedialog
import openpyxl, os, csv
from openpyxl.utils import get_column_letter, column_index_from_string

# Output File
outputFile = open('output.csv', 'w', newline='')
outputWriter = csv.writer(outputFile)
outputWriter.writerow(["Worksheet Number", "Value Not Found", "Location of Cell"])  # add columns

# Tk initialization for file dialog
root = tk.Tk()
root.withdraw()

# Number of sheets to be compared
number = input('Enter number of workbook sheets for comparison: ')
number = int(number)

# Functions for generating file paths
def generate_file_path():
    file_path = filedialog.askopenfilename(title="Open Workbook")
    return file_path


# Variables to store file paths, workbooks and worksheets
all_ws = []


# Core function for program's logistics
def core(number_of_worksheets, location_matters=False):
    # for loops for generating file paths, workbooks and worsheets
    for x in range(number_of_worksheets):
        path = generate_file_path()
        wb = openpyxl.load_workbook(path)
        ws = wb['CBF']
        all_ws.append(ws)
    root.destroy()  # destroy tk when you're done with it

    # for loop to use for loading first workbook's values into list
    sheet_cols = []
    for row in all_ws[0].iter_cols():  # using the 1st ws here instead of the 2nd
        for cellz in row:
            sheet_cols.append(cellz.value)

    # loop that checks if the value does not exist in first ws
    for ws_diff in range(1, number):
        for row, row2 in zip(all_ws[0].iter_cols(), all_ws[ws_diff].iter_cols()):
            for cell, cell2 in zip(row, row2):
                if location_matters:
                    if cell.value != cell2.value:
                        outputWriter.writerow([ws_diff, str(cell2.value), cell.coordinate])
                else:
                    if cell2.value not in sheet_cols:
                        outputWriter.writerow([ws_diff, str(cell2.value), "N/A"])


if __name__ == '__main__':
    core(number_of_worksheets=number, location_matters=False)

Openpyxl比较两张纸上的值以查看值是否不存在
