I was wondering since there are so many optinos to install a python package which one is be best and most convenient. should I install packages with sudo and pip3 commands,
E.g
sudo pip3 install <package>
only using pip3
E.g
pip3 install <package>
or using apt
sudo apt install <python-package>
I was wondering which is the go-to and will be most convenient in the future. Mostly wondering what is the difference between Sudo pip3 and pip3 what difference does it make and which one I should use.

Don't use sudo with pip. There is a chance you'll overwrite system-installed packages, and mess up your OS.
sudo apt install <python-package> is pretty safe, but may result in outdated packages, and will definitely not include all packages you may want to install.
pip3 install <package> will install packages for just the current user (thus, not system-wide; if you're the only user, you're fine), and is what I would recommend.
Going further, virtual environment or use of Conda (an "extended" virtual environment manager) are potentially even safer, at the cost of a little more work to set up, and a bit more disk space (usually, the latter is insignificant).
You will have to read up on the use of virtual environment or Conda. That topic is too long for a standard answer here.

I would suggest as first step reading package documentation, as it often contains information regarding how to install it. Few examples regarding popular packages
click suggests pip install click
jinja2 suggests pip install Jinja2
requests suggests python -m pip install requests
Before that check to what version pertains python in your machine (by checking output of python --version), if it is Python 2 and you want to install packages to Python 3, then you need to use pip3 and python3 rather than pip and python, if it is Python 3 you might use command as they are.

I was following the tutorial on Ansible docs but was unable to finish it:
$ python -m pip install --user ansible
Returns an error:
/usr/bin/python: No module named pip
While another guide installed it by using python-pip3 and then after running pip3 install --user ansible it was ready to go.
It finishes installation successfully, yet ansible is still not available:
-bash: /usr/bin/ansible: No such file or directory
I have never worked with Python or PIP in the past and I don't understand what could go wrong in the process to start debugging.

You should check your python version in the terminal with
$ which python
command and then this returns a path that contains python(probably this will return a path because almost all of Linux distro contains python). After that result, you could type
$ curl https://bootstrap.pypa.io/get-pip.py
in the terminal, and then type
$ python get-pip.py
pip will be installed after these commands.

I have not found a solution to this but instead I went with the CentOS Epel repository also described in the Ansible docs and it works this way.
sudo yum install epel-release
sudo yum install ansible
Edit: Ok, so all I had to do is to add the following to .bashrc file.
export PATH="$HOME/.local/bin:$PATH"
Fixed.

I have python 3 installed on my mac. I have installed packages via python3 pip install up until now, but if I try to use pip install I'm getting pip not found error. How do I resolve this?
p.s: I just want to install packages via pip install and not python3 -m pip install.

You can set alias in your ~/.bash_profile and try
alias pip=pip3
#or
alias pip=python3 pip

I have found in the end that this is the right way to do it:
https://opensource.com/article/19/5/python-3-default-mac
The actions to take in order to achieve this it's easy.
Take the first 3 steps from the blog.
After that you can install any of versions available from this list, using this command to show it:
pyenv install -l
Why you should do this way requires you to read the entire post.

Change alias in your terminal profile file
if you use bash goto ~/.bashrc file and
alias pip=pip3
if you use zsh goto ~/.zshrc file and do the same

do this on terminal:
alias pip=pip3
or use :
pip3 install <library_name>

On my ubuntu server, some of the installed python packages are simple pip install some are sudo pip install. Is there any way I can give sudo permission to simple pip install?
Note: There is around 250+ package. Installing one by one is quite hectic.
Please help.

Create requirements.txt file through cmd: pip freeze > requirements.txt
it'll list all the python installed packages in you're system to that file. once you got the all packages install using either sudo or normal pip.
with sudo: sudo pip install -r requirements.txt
with out sudo : pip install -r requirements.txt
i hope this will help you.

My various Python upgrades, both Ubuntu and OSX, are so gnarled that I can't escape with virtualenv 'cause virtualenv itself doesn't work. I want to lift off and nuke the site from orbit, it's the only way to be sure.
What is the easiest way to uninstall any upgrades, returning the machines to installed defaults, and proceed forward with 2.7 in a virtual environment?
EDIT: Please to note, I installed 2.7 from source on both systems.
EDIT: I've voted to close -- out of place here, and I've figured out enough to get me through the next thing. Thx to all for reading.

To remove python installed from source:
First try
sudo make uninstall
Last time I checked, Python's source Makefile does not come with an uninstall target, but just in case things have changed, it does not hurt to try this.
Assuming that does not work, install checkinstall:
sudo apt-get install checkinstall # install the checkinstall package
cd /path/to/python/source/
sudo checkinstall -D --fstrans=no make install # make the deb package
This will create a .deb file for all the files installed by make install.
checkinstall will ask a few questions; the default answers should be fine.
You should end up with a deb package called something like Python-2.7.deb
Now you can uninstall python with
sudo dpkg -r Python-2.7 # Change Python2.7 to the name of the deb package.
This method has been known to work, at least for an earlier version of Python.
