Python Tutorial: pip - An in-depth look at the package management system

In this video, we will take an in-depth look at Python's package management system, pip. We'll walk through how to install, uninstall, list, and upgrade packages. We will also dive into how we can output our dependencies and install a list of dependencies.

An in-depth knowledge of pip can be a great addition to your Python tool-belt.

Hey, that's me at 6:17 ! Glad it's still useful, and thanks for the shout-out Corey :)

Those whoever asking questions about getting errors. I guess you guys are using python3.5 or later. If so Please enter 'pip3' not simply 'pip'. python pip package has been upgraded to pip3.
Thanks

[RandomShowerThoughts]

You might be the best source of programming information online. Thank you for everything

Corey, I am a new subscriber to your channel and I absolutely fell in love with all of your content from the very first video I watched !! Can't wait to go through them all and learn new things. Thank you for all the work you have put out and helping the newbie programmer community.

For update all packages : pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U

For windows user having a problem:
Press Windows + X
Open command line (Administrator)
type this -> python -m pip install --upgrade pip

[vikctar]

Man, that command to upgrade all the packages was neat.

[ramnarasimhan]

Corey, all of your videos are crisp and to the point. This one was pitch perfect. Keep up the good work.

[heshankumarasinghe]

Thank you.... This video has been I will be revisiting this video

[OttoFazzl]

These tutorials are super cool! Freeze command and requirements packages installation is very handy indeed.

[ST-wxvw]

Like your other Python videos, this one is also excellent. Corey, thank you so much!

[jcnarasimhan]

Great tutorial, a brief word on how to install or what is pip itself would have been helpful

[madhu.badiginchala]

Thank you Corey!! Crisp and to the point tutorials. Excellent!!!

[mehdihussainseo]

This management package is quite an innovative one with features that increase efficiency and ease of use.

Hi Corey,
Thank you very much for your excellent set of videos on python. Actually I am new in python, do have programming experience in 'C' long time back and have some linux experience. In this video, you have mentioned, how to upgrade all outdated packages, a better and easy way in my opinion (in bash) is

pip install -U $(pip list -o|cut -f 1 -d ' ')

This method is much simpler I think. Here, output of "pip list -o" is piped to "cut -f 1 -d ' '" which return first field (which is the package name) using white space as delimiter and output of all this is given to "pip install -U".

It would be great if you put a link to the stack overflow you refer to and / or paste the command line in the description.

[justgivemethetruth]

grep -v, --invert-match
Selected lines are those not matching any of the specified patterns.

grep -v throws away the lines that match the pattern. In this case ^ means begins the line with a -e, so ... do not include those lines in the output. The dash in the -e must be escaped with the backslash or the grep command will see it as an argument to itself and not part of the pattern to match.

The cut comment used the character following the -d ( delimiter ) to break the input line into fields and selects those fields, in this case the first field.

Finally the xargs comment feeds the input to another command in a controlled ways such that it will not overwhelm the comment with too many arguments on the shell command line. Like if you wanted to do an ls -l on thousands of files the command line would choke ... so xargs breaks the command into separate invocations to be able to manage the input.

Nice video. Just add a note for windows user.
The following powercli could be the trick to update packages in batch. Put echo as display only.
pip list -o --exclude-editable --disable-pip-version-check | Select-Object -skip 2 | % {echo "pip -U $($_ -replace '(\w+)\s+.*', '$1')"}
