python中与excel操作相关的模块：

• xlrd库：从excel中读取数据，支持xls、xlsx
• xlwt库：对excel进行修改操作，不支持对xlsx格式的修改
• xlutils库：在xlw和xlrd中，对一个已存在的文件进行修改。
• openpyxl：主要针对xlsx格式的excel进行读取和编辑。

安装方式：pip install openpyxl

import xlwt

book = xlwt.Workbook()
sheet = book.add_sheet("sheet1")
sheet.write(0,0,"id")
sheet.write(1,0,"1")
book.save("test.xls") #结尾用xlsx的话，用office打开有问题，wps打开没问题

title = ["id","name","sex","city"]
students = [
    [1,"xiaohei","男","北京"],
    [2,"xiaolan","男","北京"],
    [3,"candy","女","深圳"],
    [4,"lucy","女","北京"],
]
students.insert(0,title)

 row = 0 #行号
 for student in students: #控制行
     col = 0  # 列号
     for value in student: #控制列
         sheet.write(row,col,value)
         col+=1
     row+=1

for row,student in enumerate(students):
    for col,value in enumerate(student):
        sheet.write(row,col,value)

book.save("test.xls")

data = xlrd.open_workbook(table_name)
table = data.sheets()[0]
nrows,ncols = table.nrows,table.ncols
for i in range(1, nrows):
　　value1= table.cell(i, 1).value    获取第i行，第1列单元格数据
　　print(value1)
