Python switch statement

How does the switch statement work? The expression is evaluated once and compared with the values of each case label. If there is a match, the corresponding statements after the matching label are executed. For example, if the value of the expression is equal to constant2, statements after case constant2: are executed until break is encountered ...

Python switch statement. There are two main situations where you can say you’re working in a Boolean context in Python: if statements: conditional execution; while loops: conditional repetition; With an if statement, you can decide your programs’ path of execution depending on the truth value of some conditions. On the other hand, while loops allow you to repeat a piece of code as …
