We are going to explore one of the most interesting feature of python: an interactive command line also known as REPL <\/p>\n\n

\n

What the *$! does REPL mean?<\/h2>\n
\n

REPL acronym stands for <\/p>\n\n

    \n
  • Read (the computer reads what you typed and if it respects Python grammar rules transforms it into executable code)<\/li>\n
  • Eval (the python interpreter executes your code and get a result)<\/li>\n
  • Print (the python interpreter prints the result in a line below your text)<\/li>\n
  • Loop (Let’s start all over again)<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n
    \n

    Why should this interest me?<\/h2>\n
    \n

    Instead of writing a program the REPL allows you to add a few commands at a time and immediately see the output <\/p>\n\n

    This allow you to get an immediate feedback and quickly explore various solutions with a “live” environment; you can build your calculations stepwise: I recommend to make experiments with this when possible as this will speed up your learning. <\/p>\n<\/div>\n<\/div>\n\n

    How do I use the Python REPL<\/h2>\n
