一、先安装python以及pip 二、其次， Python的虚拟环境安装: 在github上下载 https://github.com/pypa/virtualenv/tree/master zip文件，如图： 把zip包复制到指定文件夹下并解压 将解压的文件夹cd到当前目录后安装，输入：python3 setup.py install ，如图： 安装完virtualenv 后会在python 安装目录的Script目录下看到新生成的文件，如图： 2.创建虚拟环境的目录，在任意目录中打开cmd，输入：virtualenv p3vir 此时当前目录会生成一个p3vir的目录，该目录下的文件结构： 三、Flask的环境安装: Flask的安装，cd到解压后的目录。再分别输入两个执行命令。 (1) 进入python的虚拟环境：输入 d:\PythonEnv\p3vir\Scripts\activate.bat。 (2)输入安装命令：python3 setup.py install 。 Flask 的安装，github 下载地址： https://github.com/mitsuhiko/flask . 安装步骤参照以上。 ....由于安装有误，经过无数次调试，也是无意中安装好的 ，具体内容参见如下文章： 感谢： doago 《Python Flask 开发环境搭建(Windows)》 、

问题 I want a submit button that displays an icon rather than text. The button is a field in a WTForms form. I am using Bootstrap and Open Iconic for styling and icons. How do I set the submit field to display an icon? class MyForm(Form): submit = SubmitField('') {{ form.submit }} This post refers to an icon method, but I can't find any more information on it. 回答1: The example you linked is using macros provided by Flask-Bootstrap.

问题 From a Python Flask API, I want to return an image stream and also some text in a single API response. something like this. { 'Status' : 'Success', 'message': message, 'ImageBytes': imageBytes } Also would like to know what would be the best format to use for imageBytes, so that the client applications (Java / JQuery) can parse and reconstruct the image.

Formatting on save moves import statment in VS-Code

由 帅比萌擦擦* 提交于 2021-01-21 14:38:42
问题 I am learning flask and building a app based on Corey Schafer's Youtube tutorials. I'm using VS-Code as my editor of choice. In tutorial 5 he splits his app into a package structure and when I do it I run into a problem. In my settings I enabled the "editor.formatOnSave": true and the formatter I use is autopep8. Now when I move one of my import statements from the top to the bottom of my file and save, the formatter moves it back to the top. I'm guessing its because of 'E402 - Fix module

counting unique visitors with flask

由 情到浓时终转凉″ 提交于 2021-01-21 07:58:13

However, I have the feeling this is a problem where others probably came up with
