"Avoid THIS Bad Practise In Python": An Introduction to .env Files

Hardcoding your keys / sensitive information in your scripts is a strong red flag when it comes to coding. Let me show you a better alternative by using .env files to store your sensitive information!

i really love your Python syntax which includes types both for the variables and the function return.
not a lot of python youtube channels properly uses types like that.
I'm currently learning C and Rust, and I have learned Cython before so these static typing are very important.

[@Indently]

Always happy to see an appreciator of type annotations in Python :) I programmed in Python without them for a while, and that freedom showed me why they were so important in the end. So my older tutorials might not have them always, but all my future tutorials will definitely always have them!

[@fasanojp]

An alternative is to use the Python keyring package. An advantage is that the sensitive information is not stored in plain text on the local machine.

[@alexjando4880]

Great video, but if you want to do something native to python, you could do it by using either simple json file, or by just iterating each line of the .env file and adding the environment variables yourself.

[@SonuSingh-sn8qg]

Awesome! Going to implement this tomorrow

[@dk-ww3kp]

You helped me so much with this video thank you keep up the awesome content👏🔥

[@ali-g]

Awesome video! What is the difference between a config file and a .env file?

[@antonisstellas741]

You can actually do the same job with a config file. However, generally in a config file you save non-sensitive information.

[@ozzman530]

I think this is doing the same thing when I store variables in my Linux environment. per the .profile, or .bashrc. Is that accurate? I use this method to store detail but you have to keep an eye on file permissions. On top of that I have went so far and finding ways to encrypt the info using a seed file, but again finding suitable file permissions and places to store the seed should be concerns.

[@JoePolasek]

Awesome! Now I finally understand what .env files are for :D

[@MyManJohnny]

Another option would be to create a json file, and then write a simple wrapper class that you can use to load and access the data.

[@Sinke_100]

Providing types for every variable is maybe more professional aproach, but it's so iritating, I never do it

[@doonk6004]

I keep a .env.example file in my repos whenever I need to communicate to users and other devs which environment keys need to be set up.

[@EricHuang-cc2uu]

Great video🎉, compare to normal json file or txt file, is there any advantage using .env file?

[@AliHamza-en8cn]

Great video. But anybody can have access env in local. Any alternative to be more secure and how the use in production.

[@Indently]

I don't understand what what you mean. The only person who has access to your env on local is you and whoever else uses your computer.

[@AliHamza-en8cn]

@@Indently I mean, for example, you have a project already in an exe that is passed to the end user and the script has to connect to the database if we save it in env, the people who access that computer will be able to see it and that env is not encrypted, right?

[@Moonz97]

​@@AliHamza-en8cn build a server in between those layers as a relay. So your end user connects to your server, and your server connects to the DB. More secure that way since you can control what goes in your DB and users cant access the DB directly.

[@AliHamza-en8cn]

@@Moonz97 Thanks bro for information. Any suggestions of server?

[@arnabmondal2680]

Make a a video how to atore environment variables/secret variables in github and retrieve in it the code , because if i hist the github repo on a platform like c panel , i want make sure api keys correctly retrieved

[@pfaelzer2234]

Good video, but in my case very strange. I took over the source code from you and also .env. But if I execute print('USERNAME...) I see my original USERNAME and not the USERNAME written in .env. Do you know why?

[@TheRealLAC]

In this instance, if you wish to print to console, you need a formatted string, as you are treating the print statement as plain text.
print(f"My username is {USERNAME}!")
This assumes you have imported USERNAME from the .env and already instanced and defined it in the script you are currently working in.

[@pfaelzer2234]

@@TheRealLAC under Ubuntu the variable USERNAME is reserved. If I take username it works.

helpful. thank you.
