   - activate the env:  
     + for cmd -> TextGenEnv\Scripts\activate 
     + (for git bash, source ./Scripts/activate)
     + (for linux terminal, source TextGenEnv/bin/activate)
   

2. do your required installations there
3. And when you need to create your requirements.txt do these steps,
   • activate the environment using above command
   • pip list > requirements.txt -> it will put the output of the pip list command inside the requirements.txt
   • python listreqs.py and give the path of the previously created requirements.txt

todos:

• Create a single shell script to get the job done.
• Use the python script to create a python library: It should be like a shell command,like doing Listreqs requirements.txt after activating the virtual environment should create a requirements.txt with all the installed package name and verison inside the current directory.
• Create requirements.txt from a public repo where requirements.txt is not given. Use python poetry for this.
• Create requirements.txt from base environment, using basic regex
