Switch-Case In Python

IT Switch-Case In Python @ITCHALLENGES SWIPE >>> As you may already know, Python doesn't have an in-built switch statement like other programming languages. @ITCHALLENGES SWIPE >>> The Pythonic way to implement switch statements is to use dictionary mappings... @ITCHALLENGES SWIPE >>> def months(number): switcher = { 1: "January", 2: "February", 3: "March", 4: "April", 5: "May", 6: "June", 7: "July", 8: "August", 9: "September", 10: "October", 11: "November", 12: "December" } # Returns the name of the month, but if the # number isn't found it returns "Invalid month" return switcher.get(number, "Invalid month") @ITCHALLENGES SWIPE >>> However, from Python 3.10, a new feature called Structural Pattern Matching has been added. Let's see how you can use it! @ITCHALLENGES SWIPE >>> def days(number): match number: case 1: return "Monday" case 2: return "Tuesday" case 3: return "Wednesday" case 4: return "Thursday" case 5: return "Friday" case 6: return "Saturday" case 7: return "Sunday" @ITCHALLENGES SWIPE >>> With the match-case, you can evaluate the subject in the match statement and compare it with each pattern in a case statement. @ITCHALLENGES SWIPE >>> If an exact match is not confirmed, you can use an optional wildcard _ as the matching case: def http_error(status): match status: case 400: return "Bad request" case 404: return "Not found" case _: return "Something's wrong" @ITCHALLENGES SWIPE >>> You can also combine several literals in a single pattern using | ("or"): def http_error(status): match status: case 401 | 403 | 404: return "Not allowed" @ITCHALLENGES SWIPE >>> IT Challenges @itchallenges SQL & NoSQL Big Linux Java Comparison Cheat Sheet Challenge Top VSCode Don't Write Python Extensions Code All Day Challenge Speed Test 7 Challenge C With Python Websites Challenge Windows Improve Your C++ Coming Soon Typing Speed Challenge Was this post useful to you?
