If you upgrade your pip to the last version, then you don't need to type pip3 every time(pip3 install -U pip)

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

an amazing explanation. Brief, full of useful tips, and hitting the target in the shortest period of time. Amazing tutorial. thank you so much.

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

[@emanueler]

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

'grep' is not recognized as an internal or external command, operable program or batch file.

[@sultanmuhammad7707]

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 In this video, you have mentioned, how to upgrade all outdated packages, a better and easy way in my opinion (in bash) is pip install -U $(pip list -o|cut -f 1 -d ' ') This method is much simpler I think.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".

[@sultanmuhammad7707]

You can also do the same using list of packages from "pip freeze --local" as pip install -U $(pip freeze --local |cut -f 1 -d '=')

[@Mr0o0o0o0o0o0o0o0]

For that requirements file do it have to be in a spesific folder to be read by pip? @Corey Schafer

[@PeterSodhi]

Thank you

[@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.

I'm a bit confused.

Now since I'm on a mac by default it loads the 2.7 python version which i dont care for very much. However, even though it was installed for 3.5 i cant install it for 2.7 as it gives me permission errors and simply typing any pip commands from the video in terminal errors out in -bash: pip: command not found, what do i need to do ?

[@fioo_2386]

"cat" is not a valid command in Windows, you could use "type" command as an alternative although it will later throw an error in "grep" command. If you are using Windows 10 you could install windows subsystem for linux, from the store, and you will be able to run a UNIX based terminal to check the commands. Or you could try to find alternatives for "cat", "grep" for windows and adjust the code

[@jaysanprogramming6818]

I dind't understood the freeze command. You had 3 packages installed so far but when you typed freeze it showed only one of them. Would you be kind to elaborate a little about this point?

[@jaysanprogramming6818]

It seems that the freeze command also allows to "freeze" packages versions in order to allow full compatibility. So it enforces to use outdated versions of packages if need be.

Is it common to commit to your git/version control the output from "pip freeze > requirements.txt". I really feel committing such a file would make sense. I would even want to update this file every time after running "pip install --upgrade" and push it to version control. What you guys think?

Hey Robert. Not a crazy question at all. Yes, I sometimes use Eclipse at work and the Python interpreter I have set up through Eclipse is using different Anaconda virtual environments. Also, if you're wondering if pip and conda can both co-exist as package managers, then yes they can as well.

[@riverasanchez]

Wow! this are good news! and thank you for taking the time to reply. My next move is then to install Anaconda, PyCharm and a new one I just found out about (www.geany.org/). Then start getting familiarized with virtual environments for projects specific cases, but for that I am putting together a simplified small TS440 Xeon server running windows and 32Gb Ram for the virtual environments I got at a bargain tech hunt.

I find it very difficult to properly get going with python because I have trouble getting the environment set up properly. One of them to be able to use pip. I have installed pip (just did) but when I run pip from cmd i get 'pip' is not recognized as an internal or external command? Is that something to do with system variables maybe? (I have 3 different python istalled on my system) I am not a computer scientist and are not familiar with these concepts and find it difficult to find info of what I should do, probably bc I dont really know where I should start looking. If you need inspirations for future videos there is one =) You are doing a great job, I am enjoying your videos.

[@coreyms]

Hey there. It's hard to know exactly what is going on with limited information, but I would guess that since you have 3 different versions of python installed that pip isn't being installed on the correct path. In order to get a program to run from cmd, there has to be a correct path to that program so that it knows where to look. It's been a long time since I've used Windows so I may not be the best person to answer this question. I would try Googling "not recognized as an internal or external command" and you should see several sources that show you have to get cmd to see your executables. Good luck! Wish I could be of more help.

[@Multijuicee]

Thanks for your reply! Yeah there is something weird going on. (I have muItiple python bc they came with installation of other programs) I deleted pip from where I thought it was installed, after running get-pip.py again it still say that it is up to date. I'm sure I will find out where the problem is. Thanks again for the videos.

[@justgivemethetruth]

you need to give it the full path, or include the directory where pip resides in your path environment variable. A lot of python commands are not located in the usual system places where the normal path variable tells them where to look. Python3 on my mac is in an long path set up by the installer. There are differing ways I can use the command according to the OS.
