一、需要用到的庫：

1.操作xls格式的表格檔案：

讀取：xlrd

寫入：xlwt

修改（追加寫入）：xlutils

2.操作xlsx格式的表格檔案：

讀取/寫入：openpyxl

二、實現程式碼

1.操作xls格式的表格檔案：

# coding=UTF-8
import xlrd
import xlwt
from xlutils.copy import copy


def write_excel_xls(path, sheet_name, value):
    index = len(value)  # 獲取需要寫入資料的行數
    workbook = xlwt.Workbook()  # 新建一個工作簿
    sheet = workbook.add_sheet(sheet_name)  # 在工作簿中新建一個表格
    for i in range(0, index):
        for j in range(0, len(value[i])):
            sheet.write(i, j, value[i][j])  # 像表格中寫入資料（對應的行和列）
    workbook.save(path)  # 儲存工作簿
    print("xls格式表格寫入資料成功！")


def write_excel_xls_append(path, value):
    index = len(value)  # 獲取需要寫入資料的行數
    workbook = xlrd.open_workbook(path)  # 開啟工作簿
    sheets = workbook.sheet_names()  # 獲取工作簿中的所有表格
    worksheet = workbook.sheet_by_name(sheets[0])  # 獲取工作簿中所有表格中的的第一個表格
    rows_old = worksheet.nrows  # 獲取表格中已存在的資料的行數
    new_workbook = copy(workbook)  # 將xlrd物件拷貝轉化為xlwt物件
    new_worksheet = new_workbook.get_sheet(0)  # 獲取轉化後工作簿中的第一個表格
    for i in range(0, index):
        for j in range(0, len(value[i])):
            new_worksheet.write(i+rows_old, j, value[i][j])  # 追加寫入資料，注意是從i+rows_old行開始寫入
    new_workbook.save(path)  # 儲存工作簿
    print("xls格式表格【追加】寫入資料成功！")


def read_excel_xls(path):
    workbook = xlrd.open_workbook(path)  # 開啟工作簿
    sheets = workbook.sheet_names()  # 獲取工作簿中的所有表格
    worksheet = workbook.sheet_by_name(sheets[0])  # 獲取工作簿中所有表格中的的第一個表格
    for i in range(0, worksheet.nrows):
        for j in range(0, worksheet.ncols):
            print(worksheet.cell_value(i, j), "\t", end="")  # 逐行逐列讀取資料
        print()


book_name_xls = 'xls格式測試工作簿.xls'

sheet_name_xls = 'xls格式測試表'

value_title = [["姓名", "性別", "年齡", "城市", "職業"],]

value1 = [["張三", "男", "19", "杭州", "研發工程師"],
          ["李四", "男", "22", "北京", "醫生"],
          ["王五", "女", "33", "珠海", "計程車司機"],]

value2 = [["Tom", "男", "21", "西安", "測試工程師"],
          ["Jones", "女", "34", "上海", "產品經理"],
          ["Cat", "女", "56", "上海", "教師"],]


write_excel_xls(book_name_xls, sheet_name_xls, value_title)
write_excel_xls_append(book_name_xls, value1)
write_excel_xls_append(book_name_xls, value2)
read_excel_xls(book_name_xls)
 

2.操作xlsx格式的表格檔案：

# coding=UTF-8
import openpyxl


def write_excel_xlsx(path, sheet_name, value):
    index = len(value)
    workbook = openpyxl.Workbook()
    sheet = workbook.active
    sheet.title = sheet_name
    for i in range(0, index):
        for j in range(0, len(value[i])):
            sheet.cell(row=i+1, column=j+1, value=str(value[i][j]))
    workbook.save(path)
    print("xlsx格式表格寫入資料成功！")


def read_excel_xlsx(path, sheet_name):
    workbook = openpyxl.load_workbook(path)
    # sheet = wb.get_sheet_by_name(sheet_name)這種方式已經棄用，不建議使用
    sheet = workbook[sheet_name]
    for row in sheet.rows:
        for cell in row:
            print(cell.value, "\t", end="")
        print()


book_name_xlsx = 'xlsx格式測試工作簿.xlsx'

sheet_name_xlsx = 'xlsx格式測試表'

value3 = [["姓名", "性別", "年齡", "城市", "職業"],
          ["111", "女", "66", "石家莊", "運維工程師"],
          ["222", "男", "55", "南京", "飯店老闆"],
          ["333", "女", "27", "蘇州", "保安"],]


write_excel_xlsx(book_name_xlsx, sheet_name_xlsx, value3)
read_excel_xlsx(book_name_xlsx, sheet_name_xlsx)
 

三、執行結果
