Why Do We Use #!/usr/bin/env Python On The First Line Of A Python Script?

Hey Megha,
If in case you have installed several versions of python, the #!/usr/bin/env ensures that the interpreter will use the first installed or default version of python on your system. The other one would be to hardcode #!/usr/bin python but less flexible.

We use #!/usr/bin/env python instead of #!/usr/bin python because it is required to specify an absolute path to the program, and #!/usr/bin/env python that helps the user’s path to run an application and thus, it is more portable.
