Development environment Python

Although there are many articles on the web that are built in Python development environment, it is necessary to repeat the wheel, record the process, make it easy for you to configure later, and also facilitate your colleagues in the study to configure their environment.

1. Prepare the installation package

1) on the Python website to download the Python Operating Environment (https://www.python.org/downloads/), the more stable is the python-3.5.2

2) Download the latest version of the IDE (http://www.jetbrains.com/pycharm/download/#section =windows) on Pycharm website, which offers three versions of Mac, Windows and Linux I'm under the Pycharm-community-2016.2.3.exe.

Generally use a custom installation is better, or the automatic installation will install the environment in the personal directory, sometimes it is difficult to find

Another tick on the front of the second red box is hit, otherwise you will need to manually add the Python installation path in the path to the Windows environment variable

　　

　　

The installation path will be modified manually, can be installed to the C drive can also be installed to the D drive

　　

Complete the installation

Then we open cmd, enter Python inside, and we can go directly into the code.

Here is the selection of the IDE editing interface skin, generally using black gray words do not look so dazzling, eye better, here you can also choose to set in the inside.

The installation was successful after submission.

The method of Chinese

To download a Chinese package on the internet renamed Resources_cn.jar, and then directly copied to the installation path in the Lib folder, re-open the IDE is automatically Chinese

To cancel the Han, just delete this file, re-open the IDE to automatically restore the English version

Do not recommend the Chinese, because after the Chinese has a bit of function can not be used or can not be clicked

　　

　　

To configure the editing interface skin, you can configure it as follows. Normal fonts are smaller by default, or they can be modified by the following configuration.

　　

　　

Here the list item selection can use different skins

　　

When using the default item, the font size cannot be modified directly, click Save As ... Save As, you can modify

　　

　　

Save As, you can now directly modify the

3. Installation of Python packages

There are two ways to install a package, one is to use the command line, and one is to select the IDE to install

1) command line installation method

Open cmd, enter pip install flask (the name of the package you want to install), press ENTER to start the installation

　　

　　

Wait a minute, the installation is successful.

Generally we need to upgrade the PIP to the latest version, which will reduce the installation problem

Enter the following command in CMD and the PIP upgrade will start

1	pip install https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9

　　

　　

　　

We enter in cmd: Pip--version can see the current PIP version.

　　

　　

In case PIP upgrade fails, do not be afraid, you can download the installation package to the Python website to install the upgrade

In the browser address bar, type: HTTPS://PYPI.PYTHON.ORG/PYPI/PIP

　　

Download the installation package and unzip to the C packing directory

　　

Enter the command under DOS, enter the pip-9.0.1 folder, and enter: Python setup.py install into PIP installation

　　

　　

Completing the PIP upgrade operation

2) How to install the IDE

Open IDE, click: File = Default Settings

　　

Then select Project Interpreter to see the list of Python packages that have been installed, click the + in the top right corner to enter the installation package selection screen

　　

In the top search box, enter the name of the package you want to install, you can search for the installation package, and then select it, click on the lower left corner of the install Package,ide will start to enter the download installation, if the cause of the network caused the installation failure, you can click on other items and then point back, then point to install, After several times can be installed successfully, repeatedly after the installation is not successful, you can click to see the cause of the error, you can also use the command mode, directly see the cause of the error.

　　

Once you've done this, you're ready to start developing the Pythont program.
