With Python 3.10, thematch-casestatement provides an alternative for certain conditional checks. This new feature is particularly useful when you have a series of conditions to check and want to avoid the nested
So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif....
For Python versions < 3.10 however, there was no such statementthat is able to select a specified action based on the value of a particular variable. Instead, we usually had to write a statement incorporating multiple if-else statements or even create a dictionary that we could then be indexe...
Introduced in Python 3.10 as the match-case statement, it replaces complex if-elif chains with elegant pattern matching. Python programming has changed a lot. For years, people wanted something like the switch statements in other languages. They finally got it in 2021 with Python 3.10. But fir...
The main reason to avoid using them as do-nothing statements is that they’re unidiomatic. When you use them, it’s not obvious to people who read your code why they’re there. In general, the pass statement, while taking more characters to write than, say, 0, is the best way to...

In our output, you can see x counts to the number 5, then outputs the two print statements in our else block. Lastly, it outputs that we have exited the while loop and the else block. The value of x is 1 The value of x is 2 The value of x is 3 The value of x is 4 The ...

if, while and for statements are fundamental to all Python programs. These statements can be influenced by what are known as control statements, allowing you to govern your code in different ways. The three control statements in Python are pass, continue and break. This article looks specifically...
