I need to install Python 3.5+ on Rasbian (Debian for the Raspberry Pi). Currently only version 3.4 is supported. For the sources I want to compile I have to install:

sudo apt-get install -y python3 python-empy python3-dev python3-empy python3-nose python3-pip python3-setuptools python3-vcstool pydocstyle pyflakes python3-coverage python3-mock python3-pep8

But I think that apt-get will install more than these packages, for example libpython3-dev.

I already install python3 from https://www.python.org/downloads/ but I think, that is not complete.

Can you give me some suggestion which way is the best to get this?

A similar question was posted here Install Python 3.5 with pip on Debian 8 but this solution seems not to work on arm64.

Edit:

regarding to the comment of Padraic Cunningham: The first step I have done before. The second one results into this:

$ sudo python3.5 get-pip.py
Traceback (most recent call last):File "get-pip.py", line 19177, in <module>main()File "get-pip.py", line 194, in mainbootstrap(tmpdir=tmpdir)File "get-pip.py", line 82, in bootstrapimport pipFile "/tmp/tmpoe3rjlw3/pip.zip/pip/__init__.py", line 16, in <module>File "/tmp/tmpoe3rjlw3/pip.zip/pip/vcs/subversion.py", line 9, in <module>File "/tmp/tmpoe3rjlw3/pip.zip/pip/index.py", line 30, in <module>File "/tmp/tmpoe3rjlw3/pip.zip/pip/wheel.py", line 39, in <module>File "/tmp/tmpoe3rjlw3/pip.zip/pip/_vendor/distlib/scripts.py", line 14, in <module>File "/tmp/tmpoe3rjlw3/pip.zip/pip/_vendor/distlib/compat.py", line 66, in <module>

Head over to the RaspberryPi stackexchange and follow these instructions. To summarize:

sudo apt-get install build-essential libc6-dev
sudo apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev
sudo apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev
sudo apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
cd $HOME
wget https://www.python.org/ftp/python/3.8.6/Python-3.8.6.tgz
tar -zxvf Python-3.8.6.tgz
cd Python-3.8.6
./configure       # 3 min 13 s
# Let's use 4 threads
make -j4          # 8 min 29 s
sudo make install # ~ 4 min
cd ..
sudo rm -fr ./Python-3.8.6*
# upgrade:
sudo pip3 install -U pip
sudo pip3 install -U setuptools

(Note: he approximate times shown were measurements for the older python 3.5.2.)
