Python实现读取并写入Excel文件过程解析

# coding=utf-8

import xlrd
import xlwt

# 打开文件
#data = xlrd.open_workbook('./附件7：溶洞钻孔、埋管、注浆.xlsx')

# 查看工作表
#data.sheet_names()
#print("sheets：" + str(data.sheet_names()))

# 通过文件名获得工作表,获取工作表1
#table = data.sheet_by_name('20200404')

# 打印data.sheet_names()可发现，返回的值为一个列表，通过对列表索引操作获得工作表1
# table = data.sheet_by_index(0)

# 获取行数和列数
# 行数：table.nrows
# 列数：table.ncols
#print("总行数：" + str(table.nrows))
#print("总列数：" + str(table.ncols))

# 获取整行的值 和整列的值，返回的结果为数组
# 整行值：table.row_values(start,end)
# 整列值：table.col_values(start,end)
# 参数 start 为从第几个开始打印，
# end为打印到那个位置结束，默认为none
#print("整行值：" + str(table.row_values(0)))
#print("整列值：" + str(table.col_values(1)))

# 获取某个单元格的值，例如获取B3单元格值
#cel_B3 = table.cell(3,2).value
#print("第三行第二列的值：" + cel_B3)
