What is requirements.txt file in Short?
It is the text file (notepad file) generated by the simple command in which that file you will find all the packages that your project is using. You can read the package name and also the specific version that you have installed for your project.
As you are seeing we are discussing requirements.txt file. The filename ‘requirements’ is optional. We can give another name also.

How to create requirements.txt file
It is a very simple way to create a requirement file using the command. There is a different way you can create because sometimes it generates some issue, it may problem that which operating system you are using. I share some commands you can generate your project requriement.txt file very easily.
pip freeze > requirements.txt
But you should know, the updated version of Python is 3. So most of the time Python version 2 commands did no work now, we have to mention 3 with pip commands. as you are seeing we are using pip without mentioning 3.
To analyze both commands,
pip3 freeze > requirements.txt # it is for Python3
pip freeze > requirements.txt # it is for Python2
when you run this command you will find a txt file in your root directory or depend upon your location where you run the command.
so in the place of requirements, you can give another name also as:
pip3 freeze > required.txtÂ
In the case of Anaconda, so running the following command from conda terminal inside the environment and will also create a requirements txt file
conda list -e > requirements.txt
If you have any issues while running this command then please share your problem.
