Day 1

For the initial refresh of my Python Programming started with the print statements, format, float/string display, concatenation (with/out space), displaying special character (such as \ (backslash), " (double-quotes))

For all the the programming execution used the online compilers (link: https://www.programiz.com/python-programming/online-compiler/)

My PC also having Python 3.12.x

PS C:\Users\usr> python --version
Python 3.12.3
