首先安装xlrd模块：pip install xlrd ,核心代码网上有很多，这里主要是关于一些个人实际碰到问题细节的处理 1、excel数据不规范导致读取的数据存在空白行和列； 2、参数化执行sql 代码如下，仅供参考： 1 import xlrd 2 3 import AppSetting.AppConfig as config 4 import AppSetting.dbConfig as db 5 6 # 处理excel依赖xlrd模块 pip install xlrd 7 8 # 读取excel文件 9 excel_data = xlrd.open_workbook(config.file_path) 10 # 获取第一个sheet页 11 sheet = excel_data.sheet_by_index(0) 12 # 总行数 13 rows = sheet.nrows 14 # 获取列(经常读取到的excel可能存在空白行或者空白列，这里根据第一行的数据获取要导入的数据的列数) 15 rowlsts = [i for i in sheet.row_values(0) if i != '' ] 16 cursor = db.connect.cursor() 17 # 定义变量n，当n=0 时组装参数化的sql 18 n = 0 19 sql = "" 20 #

问题 I'm a newbie to Python and this is the first time I've tried debug mode. I've read the answers to almost similar questions on stackoverflow but none of them seem to address this situation: When I run this code in debug mode (IDLE, Windows 10): import xlrd print('Hello World!') and set a break-point on print('Hello World") and try to step through the code, I get the following error lines: > **Traceback (most recent call last): File "D:/data/python/hello_world.py", line 4, in <module> > import

How to use xlrd for writing an excel file

由 南笙酒味 提交于 2021-02-08 07:47:39
问题 How can I write an excel file(xls/xlsx) using xlrd module alone? I tried from xlrd import xlsx , but couldn't find anything that will really help me. 回答1: xlrd only reads excel files. To write them, look up xlwt, xlutils, xlsxwriter, or openpyxl - all of these packages can write binary files excel can read. Excel can also read csv files, which the csv package (included with Python) can write (and read). 来源： https://stackoverflow.com/questions/41886791/how-to-use-xlrd-for-writing-an-excel-file

Why is python xlrd errors when opening a .xlsm instead of .xls

由 本小妞迷上赌 提交于 2021-01-28 05:24:54
问题 Python program opens .xls just fine but will not open .xlsm and immediately fails. xlrd.open_workbook("Some filename.xlsm") Error: Exception has occurred: AttributeError 'bytes' object has no attribute 'seek' Any help would be greatly appreciated... 回答1: For those who run into this.

问题 I have been working on a script on Windows and now when changing the platform to Linux/Ubuntu I am having some issues.

问题 I'm working with Django and need to read the sheets and cells of an uploaded xlsx file. It should be possible with xlrd but because the file has to stay in memory and may not be saved to a location I'm not sure how to continue. The start point in this case is a web page with an upload input and a submit button. When submitted the file is caught with request.FILES['xlsx_file'].file and send to a processing class that would have to extract all the important data for further processing. The type
