I like that pip didn't run on the first try, and he showed us how to fix it. That was cool.

A good programmer will always taste his code.
Good stuff.

Concise, useful, a touch of humor.
Nicely done.

in order to install pytest, you changed the permission of installation directory. it works but it is not a great solution

it will work if you run command prompt as administrator.

[Pterryreal]

Use "pip install pytest --user" instead of changing the directory permissions!

[techcode_man]

Nice tutorial. Short and sweet to the point.

[tinokanngieer]

So you advise to give all users write permission to the folder instead of running the shell with admin rights?! 😏

[evolagenda]

A good programmer will always give write permission to all users instead of using an elevated prompt.

hahah dude, that meme in the beginning.
About a week and a half ago I started a personal toy project that is now 1640 lines long. The yesterday I broke it and I felt a little panic I haven't felt in a while... I can't imagine how it feels if that happened in any costly way!.

Also, every time I change a function, I have to manually run all the functions that depend on that little tidbit... also, every line of code I type, I have to have in mind how all the code works... i'm becoming a "why you should test your code" poster boy.

Hi. The python -m pytest works for me but when it comes to the the py.test and py.test-v, there’s error stating “cannot find path”, “not recognized” or “can’t open file”, .. Any idea on how to fix it everyone? Thank you sooo much
