datetime的解决办法 混合数据的表中有个日期:2016/9/18 通过table.row_values(row_number)[1]读取时,显示的结果为:42631.0 查看row_values方法的源码: def row_values(self, rowx, start_colx=0, end_colx=None): if end_colx is None: return self._cell_values[rowx][start_colx:] return self._cell_values[rowx][start_colx:end_colx] 1 2 3 4 也就是说返回了self._cell_values,self._cell_values在源码中的定义为:self._cell_values = [],这就是问题的根源 第一种解决办法: xldate.xldate_as_datetime把日期转换回来 xldate.xldate_as_datetime(table.row_values(row_number)[1], 0) 1 2 第二种解决办法: 先用xldate.xldate_as_tuple(table.row_values(row_number)[1],0) 显示结果为:(2016, 9, 27, 0, 0, 0) xldate_as_tuple源码部分: #

一、安装xlrd模块 到python官网下载http://pypi.python.org/pypi/xlrd模块安装,前提是已经安装了python 环境。 二、使用介绍 1、导入模块 import xlrd 2、打开Excel文件读取数据 data = xlrd.open_workbook('excelFile.xls') 3、使用技巧 获取一个工作表 table = data.sheets()[0] #通过索引顺序获取 table = data.sheet_by_index(0) #通过索引顺序获取 table = data.sheet_by_name(u'Sheet1')#通过名称获取 获取整行和整列的值(数组) table.row_values(i) table.col_values(i) 获取行数和列数 nrows = table.nrows ncols = table.ncols 循环行列表数据 for i in range(nrows ): print table.row_values(i) 单元格 cell_A1 = table.cell(0,0).value cell_C4 = table.cell(2,3).value 使用行列索引 cell_A1 = table.row(0)[0].value cell_A2 = table.col(1)[0].value

问题 I am working with RapidMiner at the moment and am trying to copy my RapidMiner results which are in xlsx files to txt files in order to do some further processing with python. I do have plain text in column A (A1-A1500) as well as the according filename in column C (C1-C1500). Now my question: Is there any possibility (I am thinking of the xlrd module) to read the content of every cell in column A and print this to a new created txt file with the filename being given in corresponding column C

Excel表操作 python操作 excel主要用到 xlrd和 xlwt这两个库,即 xlrd是读 excel, xlwt是写 excel的库。 安装xlrd pip install xlrd 简单的表格读取 import xlrd #读取表格 data=xlrd.open_workbook("table.xlsx") #获取表格的sheets table=data.sheets()[0] #输出行数量 print(table.nrows)#8 #输出列数量 print(table.ncols)#4 #获取第一行数据 row1data=table.row_values(0) print(row1data)#['列1', '列2', '列3', '列4'] print(row1data[0])#列1 数据可视化 pyecharts 是一个用于生成 Echarts 图表的类库。 Echarts 是百度开源的一个数据可视化 JS 库。用 Echarts 生成的图可视化效果非常棒,为了与 Python 进行对接,方便在 Python 中直接使用数据生成图 安装 pip install pyecharts 读取Excel数据及显示 import xlrd from pyecharts.charts import Bar #读取表格 data=xlrd.open_workbook(
