 ====== Python3 Interactive Interpreter ====== ====== Python3 Interactive Interpreter ======
 +The Python3 interactive interpreter (typically invoked with ''python3'' on the command line) allows for the entry of arbitrary Python3 commands, making it a great calculator and a great place to test simple ideas. The interpreter should feel familiar to users of shells made popular in many operating systems and [[https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop|read-eval-print]] loops in other languages.
  
 +===== Invocation =====
 +In Linux the interactive interpreter is invoked directly by calling ''python3'' without any arguments (e.g., a ''.py'' file to execute). In Windows this is bundled into the [[https://en.wikipedia.org/wiki/IDLE|IDLE]] [[https://en.wikipedia.org/wiki/Integrated_development_environment|development environment]].

 +==== Loops ==== 
 +The interactive interpreter is quite limited compared to what can be accomplished in an actual Python3 program (i.e., a ''.py'' file), however its functionality can be easily extended slightly beyond that of one-liners. (Nested) Loops can be quickly tested in order to evaluate syntax and functionality.
