The current version of Python is 3.x . However there is a lot of existing software out there which is in 2.x so I am sticking with 2.7 . There are various differences between Python 3 and Python 2 but they are not very major and at a certain stage later on you can easily transition to Python 3 . Python 2.7 official support will end in the year 2020 so still a few years to go .<\/p>\n
INSTALLING PYTHON<\/h3>\n
This part is quite simple. Just head over to the official downloads page\u00a0https:\/\/www.python.org\/downloads\/<\/a>\u00a0and the website will automatically detect what OS you are on and give you download options for that platform. It will offer you download options for version 3.x and 2.x Make sure to choose the 2.x option.<\/p>\n For MacOS and Windows, you can download installers which then install Python in your system.<\/p>\n For Linux, if you are using a Debian<\/strong> or a Debian variant like Ubuntu<\/strong>, the following commands should do the trick<\/p>\n For Fedora:<\/strong><\/p>\n For CentOS\/RHEL<\/strong> On EPEL 7 (but not EPEL 6), you can install wheel:<\/p>\n For OpenSUSE<\/strong><\/p>\n We will be using the command line Python interpreter for all the lessons in the Fundamentals section. Open a command prompt . For Windows users if the Python folder has not been added to the system PATH variable, you will have to navigate to the Python installation folder eg. c:\\python2.7 and then run the Python interpreter from there.<\/p>\n So lets load the Python interpreter. Just type python\u00a0<\/strong>and press Enter<\/p>\n You should see something similar to this:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n For now just type in<\/p>\n print “Hello World”<\/em><\/p>\n and press Enter<\/p>\n That’s it. You have just written your first Python statement.
