python3 读写Excel
说明
- 2007版以前的Excel（xls结尾的），需要使用xlrd读，xlwt写。
- 2007版以后的Excel（xlsx结尾的），需要使用openpyxl来读写。

# 读写2003 excel
import xlrd

# 读写2007 excel
import openpyxl
def write03Excel(path):
wb = xlwt.Workbook()
sheet = wb.add_sheet("2003测试表")
value = [["名称", "价格", "出版社", "语言"],
["如何高效读懂一本书", "22.3", "机械工业出版社", "中文"],
["暗时间", "32.4", "人民邮电出版社", "中文"],
["拆掉思维里的墙", "26.7", "机械工业出版社", "中文"]]
for i in range(0, 4):
for j in range(0, len(value[i])):
sheet.write(i, j, value[i][j])
wb.save(path)
print("写入数据成功！")

for j in range(0, worksheet.ncols):

print()
file_2003 = 'data/2003.xls'
file_2007 = 'data/2007.xlsx'
write03Excel(file_2003)
read03Excel(file_2003)
write07Excel(file_2007)
read07Excel(file_2007)一切尽在demo中。
