indented is the way python uses grouping statements. At the interactive prompt, you have to enter a tab or several spaces for the contraction. In practice, you need a text editor to prepare more complex input. All the better text editors have the automatic indent function. When a compound statement is input interactively, it must be followed by an empty line (because the parser cannot guess when you enter the last line ). Remember, each line in a bas
