使用 python 将 xlsx 文件复制到另一个文件时遇到问题

Question

所以这对你们中的某些人来说可能看起来很傻，但我是 python 的新人，所以我不太清楚发生了什么，

我需要删除 excel sheet 的第一列和前 7 行，查找后我在这个网站上找到了打开另一个文件并只处理我需要的内容会更容易，所以我尝试了这样的事情

import openpyxl



#File to be copied

wb = openpyxl.load_workbook(r"C:\Users\gb2gaet\Nova pasta\old.xlsx") #Add file name

sheet = wb["Sheet1"]#Add Sheet name



#File to be pasted into

template = openpyxl.load_workbook(r"C:\Users\gb2gaet\Nova pasta\new.xlsx") #Add file name

temp_sheet = wb["Sheet1"] #Add Sheet name



#Takes: start cell, end cell, and sheet you want to copy from.

def copyRange(startCol, startRow, endCol, endRow, sheet):

    rangeSelected = []

    #Loops through selected Rows

    for i in range(startRow,endRow + 1,1):

        #Appends the row to a RowSelected list

        rowSelected = []

        for j in range(startCol,endCol+1,1):

            rowSelected.append(sheet.cell(row = i, column = j).value)

        #Adds the RowSelected List and nests inside the rangeSelected

        rangeSelected.append(rowSelected)



    return rangeSelected



#Paste data from copyRange into template sheet

def pasteRange(startCol, startRow, endCol, endRow, sheetReceiving, copiedData):

    countRow = 0

    for i in range(startRow,endRow+1,1):

        countCol = 0

        for j in range(startCol,endCol+1,1):

       

            sheetReceiving.cell(row = i, column = j).value = copiedData[countRow][countCol]

            countCol += 1

        countRow += 1



def createData():

    print("Processing...")

    selectedRange = copyRange(2,8,17,100000,sheet)

    pasteRange(1,1,16,100000,temp_sheet,selectedRange)

    wb.save("new.xlsx")

    print("Range copied and pasted!")

程序运行没有任何错误，但是当我查看新的 table 时它完全是空的，我错过了什么？如果你们能想到任何更简单的解决方案来删除行和列，我愿意更改所有代码

我建议通过 pandas 执行此操作。使用pandas.read_excel() 函数将excel 文件导入数据框，然后使用dataframe.drop() 函数删除所需的列和行，然后将数据框导出到新的excel 带有 to_excel() 函数的文件。

代码看起来像这样：

import pandas as pd

df = pd.read_excel(r"C:\Users\gb2gaet\Nova pasta\old.xlsx")
#careful with how this imports different sheets. If you have multiple,
#it will basically import the excel file as a dictionary of dataframes
#where each key-value pair corresponds to one sheet.

df = df.drop(columns = <columns you want removed>)

df.to_excel('new.xlsx')
#this will save the new file in the same place as your python script

以下是关于这些函数的一些文档：

read_excel(): https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_excel.html?highlight=read_excel

掉落(): https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.drop.html

to_excel(): https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_excel.html?highlight=to_excel#pandas.DataFrame.to_excel
