问题 I have windows 10 (64 bit). I want to utilize the Openpyxl package to start learning how to interact with excel and other spreadsheets. I installed Python with "windowsx86-64web-basedinstaller" I have a 64 bit OS, was I mistaken when trying to install this version? 回答1: You need to ensure that C:\Python35\Sripts is in your system path. Follow the top answer instructions here to do that: You run the command in windows command prompt, not in the python interpreter that you have open. Press: Win

How to delete rows that satisfy some criteria in an excel spreadsheet?

问题 I would like to create a "reduced" version of an Excel (xlsx) spreadsheet (i.e. by removing some rows according to some criterion), and I'd like to know if this can be done with openpyxl . In (pythonish) pseudo-code, what I want to do would look something like: wb = openpyxl.reader.excel.load_workbook('/path/to/workbook.xlsx') sh = wb.get_sheet_by_name('someworksheet') # weed out the rows of sh according to somecriterion sh.rows[:] = [r for r in sh.rows if somecriterion(r)] # save the

包和一些常用模块

包 回顾调用一个模块的过程: 1、运行执行文件,创建一个执行文件的名称空间 2、创建模块文件的名称空间 3、执行模块文件中的代码,将产生的名字放入模块的名称空间中 4、在执行文件中拿到一个指向模块名称空间的名字 定义: 包是一种通过使用 .模块名 来组织python模块名称空间的方式,包的本质还是一个模块 具体的: 包就是一个包含有__init__.py文件的文件夹,所以其实我们创建包的目的就是为了用文件夹将文件/模块组织起来 需要强调的是: 1. 在python3中,即使包下没有__init__.py文件,import 包仍然不会报错, ​而在python2中,包下一定要有该文件,否则import 包报错 2. 创建包的目的不是为了运行,而是被导入使用,​记住,包只是模块的一种形式而已,包的本质就是一种模块 首次导入包的执行过程: 1、先运行执行文件,创建一个执行文件的名称空间 2、创建包下面的__init__.py文件的名称空间 3、执行包下面的__Init__.py文件中的代码,将产生的名字放入包下面的__init__.py文件得我名称空间中 4、在执行文件中拿到一个指向包下面的__init__.py文件名称空间的名字 包的导入之注意事项: 1、包的导入可以使用import和from...import...两种。 但是无论在什么位置,导入时都要遵循一个原则:凡是导入时带点的

用Python在Excel里画出蒙娜丽莎

假如想象 提交于 2020-01-11 02:28:10
之前看到过很多头条,说哪国某人坚持了多少年自学使用excel画画,效果十分惊艳。 对于他们的耐心我十分敬佩。 但是作为一个程序员,自然也得挑战一下自己。 这种需求,我们十分钟就可以完成! 。 mona-lisa 基本思路 实现这个需求的基本思路是读取这张图片每一个像素的色彩值,然后给excel里的每一个单元格填充上颜色。所以主要用到的是 PIL 、 openpyxl 这两个库。​ PIL使用 PIL 是Python里面做图像处理的时候十分常用的一个库,功能也是十分的强大,这里只需要用到 PIL 里一小部分的功能。 from PIL import Image img = Image.open(img_path) # 读取图片 width, height = img.size # 获取图片大小 r, g, b = img.getpixel((w - 1, h - 1)) # 获取像素色彩值 Image.open() 是PIL里面打开一张图片的函数,支持多种图片类型 img_path 是图片路径,可以是相对路径,也可以是绝对路径 img.size 是获取图片的 size 属性,包含图片的宽和高 img.getpixel() 是获取图片色彩值的函数,需传入一个 tuple 或 list ,值为像素坐标 xy openpyxl使用 openpyxl

操作Excel ,使用第三方库,使用别人写好的代码, 这是使用 openpyxl 操作 2010 版之后的 xlsx 格式。 有些2003经典版是无法使用的,只能使用其他库 比如:xlrd,xlwt 。 其中 tablib 可以都支持,但是它的依赖比较大,使用起来复制,感兴趣的小伙伴可以自行百度 一、 安装 openpyxl pip install openpyxl 二、导入 openpyxl import openpyxl 1、打开 excel 文件获取工作簿 (文件内容见最下方 截图 ) # 有一个必填项,可填写 文件的路 径或者 文件对象 wb = openpyxl.load_workbook('D:\datas.xlsx') print(wb) 2、获取表单(一个excel 文件可以有过个表单) # 获取所有表单 sheet = wb.worksheets print(sheet) # 通过索引获取表单,索引从 0 开始 sheet = wb.worksheets[0]print(sheet) # 通过表单名字获取表单.有个问题,之后使用 sheet 后无法 点 出提示 sheet = wb.get_sheet_by_name('Sheet1') print(sheet) # 简洁版 通过字典的形式. 问题和上面一样 sheet = wb['Sheet1'] print
