Python3操作Excel文件

import os
import openpyxl
paths = os.path.join('C:', 'Program Files (x86)', 'Python37-32')
print(paths)
print(os.getcwd())  # 當前工作目錄
os.chdir('C:\\Program Files (x86)\\Python37')  # 修改工作目錄
print('修改後的工作目錄:', os.getcwd())  # 當前工作目錄
print(os.path.abspath('.\\test.txt'))

calcFilePath = 'C:\\Program Files (x86)\\Python37-32\\test.txt'
print('目錄名稱:',os.path.dirname(calcFilePath))  # 目錄名稱
print('基本名稱:',os.path.basename(calcFilePath))   # 基本名稱
print('同時需要目錄名稱和基本名稱:',os.path.split(calcFilePath)) 
print(os.path.exists('d:\\'))  # 判斷是否存在閃存盤

一、需要用到的庫：

1.操作xls格式的表格文件：

讀取：xlrd

寫入：xlwt

修改（追加寫入）：xlutils

2.操作xlsx格式的表格文件：

讀取/寫入：openpyxl

二、實現代碼

1.操作xls格式的表格文件：

# coding=UTF-8
import xlrd
import xlwt
from xlutils.copy import copy
 
 
def write_excel_xls(path, sheet_name, value):
    index = len(value)  # 獲取需要寫入數據的行數
    workbook = xlwt.Workbook()  # 新建一個book
    sheet = workbook.add_sheet(sheet_name)  # 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])  # 像表格中寫入數據（對應的行和列）
    workbook.save(path)  # 保存
    print("xls寫入數據成功！")
 
 
def write_excel_xls_append(path, value):
    index = len(value)  # 獲取需要寫入數據的行數
    workbook = xlrd.open_workbook(path)  # 打開工作簿
    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數據的行數
    new_workbook = copy(workbook)  # 將xlrd對象拷貝轉化爲xlwt對象
    new_worksheet = new_workbook.get_sheet(0)  # 獲取轉化後的第一個表格
    for i in range(0, index):
        for j in range(0, len(value[i])):
            new_worksheet.write(i+rows_old, j, value[i][j])  # 追加寫入數據，注意是從i+rows_old行開始寫入
    new_workbook.save(path)  # 保存
    print("xls【追加】寫入數據成功！")
 
 
def read_excel_xls(path):
    workbook = xlrd.open_workbook(path)  # 打開
    sheets = workbook.sheet_names()  # 獲取所有表格
    worksheet = workbook.sheet_by_name(sheets[0])  # 獲取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="")  # 逐行逐列讀取數據
        print()
 
 
book_name_xls = 'xls格式測試.xls'
 
sheet_name_xls = 'xls格式表'
 
value_title = [["姓名", "性別", "年齡", "城市", "職業"],]
 
value1 = [["張三", "男", "19", "深圳", "研發工程師"],
          ["李四", "男", "22", "北京", "醫生"],
          ["王五", "女", "33", "珠海", "出租車司機"],]
 
value2 = [["Tom", "男", "21", "深圳", "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格式的表格文件：

# 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寫入數據成功！")
 
 
def read_excel_xlsx(path, sheet_name):
    workbook = openpyxl.load_workbook(path)
    # sheet = wb.get_sheet_by_name(sheet_name)已經棄用
    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.xlsx'
sheet_name_xlsx = 'xlsx格式測試表'
 
value3 = [["姓名", "性別", "年齡", "城市", "職業"],
          ["111", "女", "66", "深圳", "運維工程師"],
          ["222", "男", "55", "廣州", "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)
