Python Tutorial: Calling External Commands Using the Subprocess Module

[@coreyms]

Hey everyone. I hope you found this video useful. As I mentioned in a previous post, I just finished renovating a house that I'm selling and am currently going through a cross-country move, so I haven't been able to post as much lately as I'd like. Once I get this house sold and get settled into my new place then I'll be releasing at a much faster pace. Thanks for your patience... especially those who are contributing through Patreon or are Channel Members! I appreciate all of you! Hope you're all having a great week!

[@priteshugrankar6815]

Hi Corey, happy house shifting. Thank you for such amazing content. Would you also be coming up with golang videos? If so, it will be truly awesome.

[@realplod]

Where are you moving?:)

[@buacomgiadinh1]

Is there any intention for golang programming

[@coreyms]

[@undisclosedmusic4969]

Good luck with the move! Also: Docker tutorials? ❤️

[@jonathanhenyolson]

I know you have about a million things on your to-do list but a series or video on threading would be amazing. There's pretty sparse KZbin content on it so far and one of your videos could easily fill that void! Thanks for all the great content!

[@tanmoypaul1362]

I second this. A video on threading would be awesome.

[@suhaibalrabee9399]

I couldn't find such explanation for this topic in my overpriced premium subscriptions (CBT, PS, Orielly). This should not be free, please keep up the great work, thanks!

[@coreyms]

Thanks so much!

[@ibrahimal-mahfooz8737]

Your content is as simple as sipping water for beginners. At the same time, I'm pretty sure it is so difficult to create and deliver such a clean and crystal clear content. Well done.

[@coreyms]

Thanks!

[@TexasGunDude]

I've been taking Python courses online for certificates. Corey explains Python better that my online instructors.

[@Hunt3rGatherer]

Man I watched this 3 years ago with zero knowledge of computers other than a beginner python course and my brain short circuited. I finally understand everything in this video lol. Been using your videos for years now thanks bro 🤙

[@jasonhales262]

This is by far the best explanation of the subprocess module on the WHOLE INTERNET.

[@martym2908]

I googled a dozen didn't pages to get subprocess to work and haven't succeeded until i watched this. Thanks a ton !

Corey, there's no doubt that these videos are a real must for anyone, who's learning Python.

[@bhushanhiwase121]

You are the best Corey, You have made my life so simple, and each one of your videos is so full of information and handy tricks. I really appreciate the work you put on to bring out these videos. Cannot be more Thankful... Huge Respect man...

This is the best explanation of a code I have ever seen!!

[@mayankpant5471]

this man makes everything very ez. python semantics itself are very ez but his videos makes learning python like learning alphabets.

This is what i can say linear learning look like, as it should always be, step by step and as clear as possible. Thank you a lot sir!

[@avahsieh4645]

Your tutorial helps me more than the python official document does. Thank you.

[@Jack-sh4uv]

I just want to say how helpful all your videos are, I really would get so stuck on the occasional small thing but your videos are consistently well thought out and progress at a good speed. Thanks for the help

[@kariminic]

I found this video very useful. Had came across subprocess from the automate the boring stuff book but then didn't understand their purpose untill I watched this video. Have done really cool stuff with it, I had even to revisit the module from the book. In the end you've mentioned about Unicode, I haven't found a meaningful video on the topic and books full of jargons. I bet a video from you will be my saviour in understanding the topic. Thanks @Corey for the exceptional python tutorials.

[@kaiwalyapethe2931]

Encode-decode strings, waiting for it.. Great work Corey! Thanks for the videos.

[@carlosrivadulla8903]

also how to encode an script but that still working when other user execute it to avoid copyright violation

Hi Corey, your video was fantastic! You were able to describe the content in a way that made sense. I have been trying to understand this for about 3 days now and your 19min clip nailed it to the point where i can simply grasp the concepts. In fact, i have been trying to solve a code problem and you helped me a lot. Great work and keep up the good content.

[@geekchiq5431]

Thank You for sharing your knowledge with us! So grateful and appreciate your natural gift of teaching. I swear I was only looking for insight into using the subprocess module when you answered like 4 other questions I had! lol

[@林家頡-u2h]

Hi Corey, thank you for your amazing tutorial! Your python basic tutorial really helped when I first started learning python. Just one small problem, subprocess.run(["ls", "-la"], capture_output=True) should be subprocess.run(["ls", "-l", "/dev/null"], stdout=subprocess.PIPE) on Mac (python 3.6).

[@martinalexander9210]

I had the same issue happen to me. Thanks Jimmy Lin it worked!!

[@ram-my6fl]

use python 3.7+ to have capture_output arg in subprocess.run

[@techwithdave]

As @ram was saying, it totally works in Python 3.7.9, however, I wanted to add to his comment that 'capture_output=True' doesn't work when using versions older than 3.7

[@jovy5638]

In brief, There are string type object and byte type object. You should transfer the data to bytes to store the data in hard driver , and if you want to watch what’s the meaning for human, you need to transfer bytes data to string. From string to bytes, it’s called encode. And it’s called decode in the other situation.
