I assume that you have downloaded and installed anaconda. You can now run anaconda and reach its navigation page. From this I would request you to open jupyter notebook. (This will open in your browser.
Once in jupyter notebook, press new tab (top right corner) and select python 3 option.
Another window will open. It may look like some kind of word processor. It has cell number.
In the cell type following command
print (“Hello world!”)
And press control+enter.
If you get Hello World as output.
Congratulations! You have done your first program successfully.
