 So, this will be a lightning talk and this comes from the next six years of experience on working in Python. So this is a bit about me and Python 2.4. So if you're working on a legacy systems or, you know, as a chunk of data and systems might be working on a Python 2.0 as well and that is a high chance that you'll be migrating from 2.0 to 3.0 but you need to do certain testings and you need to make sure the migrations happen properly and that is no issues when you're going to Python 3.0 as well and other motivation is there are certain systems which are still in 2.2 and even though it is depreciated, people are still using that plan and when you are working on the system you should be able to pull up that Python system and work it up on. So, let me give you and its problems what you might face when you're using a Python 2.2. So as of now, if you're using a Mac or Linux system you'll have a by default you're having a Python 2.7 and for a development purpose you might be installing any Python 3.0 text versions but the problem comes over here is when you're trying to install a new module via pip for a Python 2.7 so that your global package linkage may not happen and it will always point to Python 3.0 which if you install a package it would be installed in the Python 3.0 but it wouldn't be happening in the Python 2.1 and second thing is getting the pip for sometimes for the Python 2.0 version of latest Debian or the Petero flavors it you have to manually install it and when you're installing it you might run into a certain errors like type checking and untyped errors. So what would be the best way of doing this plan is download the actual package from the curl using a curl from the Python 2.7 one so you can download this link and get the pip file and here is what sometimes we make mistakes you have to specify the 2.7 version and by default it takes to the 3.3x version so you have to specify this one over here and then you have to install it. Now this is this is where the interesting part comes in when you're installing the pip via the script you might be getting into an type check errors or untyped errors but you can ignore them as such because you won't be directly using a pip one. Now when you are trying to install a package via pip after doing this process it will still show up in an untyped error. What would be the better way of doing this plan it would be doing it via the Python command like if this Python minus M have installed the modeling it would work. There are certain nuances that you need to follow it you need to have a Python setup tools and the wheels installed over here and that would pretty much cover for you and if there are any other doubts you can reach out to me over here.
