How to install python3.6.4 to Raspberry Pi 3rd generation

The default version that can be installed on Raspberry Pi using sudo apt-get install is Python 3.4, but many of the new features of Python 3.6 cannot be used, and your own projects cannot be run. So it needs to be upgraded.

#Currently it is not possible to simply install, you can only make and compile it yourself. (Recommended learning: Python video tutorial)
We want to install Python3.6.4 on the Raspberry Pi, so we need to compile and install this version.

The method is as follows:

# 安装编译所需依赖包
sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev 
libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

# 安装SSL依赖
sudo apt-get install libssl-dev


# 到官网下载Python3.6.4： https://www.python.org/downloads/source/
wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tar.xz

# 解压
tar xf Python-3.6.4.tar.xz 

# 进入目录
cd Python-3.6.4

# 开始编译（时间漫长，需要等待，建议用&&把三句连在一起执行）
sudo  ./configure
sudo make
sudo make install

# 升级pip
sudo python3.6 -m pip install --upgrade pip

After installing Python3.6, it will display:
