By accessing these functions or outcomes based on the key, a dictionary can effectively replicate the behavior of a switch statement, providing a flexible and efficient way to handle multiple ... Python has no switch statement. The common replacement - as you already seem to know - is using a dictionary to dispatch different behaviors. With that being the case however, the syntax you're trying to use simply isn't allowed for dictionaries. Dictionary key values should be expressions.When JavaScript reaches a break keyword, it breaks out of the switch block. This will stop the execution inside the switch block. It is not necessary to break the last case in a switch block. The block breaks (ends) there anyway. Note: If you omit the break statement, the next case will be executed even if the evaluation does not match the case.

This program declares variable i as int and the switch statement checks the value of i.The first case will be evaluated as it satisfied the condition i == 0 so i is zero will be printed..

Often the switch statement is used for comparison of an object/expression with case statements containing literals.The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed. The break statement breaks out of the switch block and stops the execution. The default statement is optional, and specifies some code to run if there is no case match.Specifically, it is an alternative to using multiple conditional statements such as if, elif or else clauses. In Python, switch-case statements are constructed using the keyword ‘switch’ followed by one or more ‘case’ blocks and an optional ‘default’ block.
