一、需要用到的库：
1.操作xls格式的表格文件：
读取：xlrd
写入：xlwt
修改（追加写入）：xlutils
2.操作xlsx格式的表格文件：
读取/写入：openpyxl
二、实现代码
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) # 获取需要写入数据的行数
workbook = xlwt.Workbook() # 新建一个工作簿
sheet = workbook.add_sheet(sheet_name) # 在工作簿中新建一个表格
for i in range(0, index):
for j in range(0, len(value[i])):
sheet.write(i, j, value[i][j]) # 像表格中写入数据（对应的行和列）
workbook.save(path) # 保存工作簿
print("xls格式表格写入数据成功！")
def write_excel_xls_append(path, value):
index = len(value) # 获取需要写入数据的行数
workbook = xlrd.open_workbook(path) # 打开工作簿
sheets = workbook.sheet_names() # 获取工作簿中的所有表格
worksheet = workbook.sheet_by_name(sheets[0]) # 获取工作簿中所有表格中的的第一个表格
rows_old = worksheet.nrows # 获取表格中已存在的数据的行数
new_workbook = copy(workbook) # 将xlrd对象拷贝转化为xlwt对象
new_worksheet = new_workbook.get_sheet(0) # 获取转化后工作簿中的第一个表格
for i in range(0, index):
for j in range(0, len(value[i])):
new_worksheet.write(i+rows_old, j, value[i][j]) # 追加写入数据，注意是从i+rows_old行开始写入
new_workbook.save(path) # 保存工作簿
print("xls格式表格【追加】写入数据成功！")
def read_excel_xls(path):
workbook = xlrd.open_workbook(path) # 打开工作簿
sheets = workbook.sheet_names() # 获取工作簿中的所有表格
worksheet = workbook.sheet_by_name(sheets[0]) # 获取工作簿中所有表格中的的第一个表格
for i in range(0, worksheet.nrows):
for j in range(0, worksheet.ncols):
print(worksheet.cell_value(i, j), "\t", end="") # 逐行逐列读取数据
print()
book_name_xls = "xls格式测试工作簿.xls"
sheet_name_xls = "xls格式测试表"
value_title = [["姓名", "性别", "年龄", "城市", "职业"],]
value1 = [["张三", "男", "19", "杭州", "研发工程师"],
["李四", "男", "22", "北京", "医生"],
["王五", "女", "33", "珠海", "出租车司机"],]
value2 = [["Tom", "男", "21", "西安", "测试工程师"],
["Jones", "女", "34", "上海", "产品经理"],
["Cat", "女", "56", "上海", "教师"],]
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格式表格写入数据成功！")
def read_excel_xlsx(path, sheet_name):
workbook = openpyxl.load_workbook(path)
# sheet = wb.get_sheet_by_name(sheet_name)这种方式已经弃用，不建议使用
sheet = workbook[sheet_name]
for row in sheet.rows:
for cell in row:
print(cell.value, "\t", end="")
print()
book_name_xlsx = "xlsx格式测试工作簿.xlsx"
sheet_name_xlsx = "xlsx格式测试表"
value3 = [["姓名", "性别", "年龄", "城市", "职业"],
["111", "女", "66", "石家庄", "运维工程师"],
["222", "男", "55", "南京", "饭店老板"],
["333", "女", "27", "苏州", "保安"],]
write_excel_xlsx(book_name_xlsx, sheet_name_xlsx, value3)
read_excel_xlsx(book_name_xlsx, sheet_name_xlsx)
三、运行结果
