Python Learning Session-03 - Conditional Execution

Conditional Steps

                                                                    Indentation

          •         Increase indent indent after an if statement or for statement (after : )

          •         Maintain indent to indicate the scope of the block (which lines are affected by the if/for)

•         Reduce indent back to the level of the if statement or for statement to indicate the end of the block

•         Blank lines are ignored - they do not affect indentation

                              •         Comments on a line by themselves are ignored with regard to indentation

                                                                    The try / except Structure

•         You surround a dangerous section of code with try and except

•         If the code in the try works - the except is skipped

•         If the code in the try fails - it jumps to the except section
