I’d like to know, is there a Python equivalent for the case statement such as the examples available on VB.net or C#?

- The second question is not a follow-up, and even follow-ups are to be posted as separate questions. In addition to that, it’s off topic, and should go on programmers.stackexchange.com. And, your first question is a duplicate.

While the official docs are happy not to provide switch, I have seen a solution using dictionaries.

For example:

# define the function blocks def zero(): print "You typed zero.\n" def sqr(): print "n is a perfect square\n" def even(): print "n is an even number\n" def prime(): print "n is a prime number\n" # map the inputs to the function blocks options = {0 : zero, 1 : sqr, 4 : sqr, 9 : sqr, 2 : even, 3 : prime, 5 : prime, 7 : prime, }

Then the equivalent switch block is invoked:

options[num]()

This begins to fall apart if you heavily depend on fall through.

The direct replacement is `if`

/`elif`

/`else`

.

However, in many cases there are better ways to do it in Python. See “Replacements for switch statement in Python?“.
