Explore Python control flow statements including if, else, and loops to manage the execution of code efficiently.
As you can see, the for loop is simpler, more expressive and less error prone in Python.The break Statement The break statement is used to break out of a loop statement i.e. stop the execution of a looping statement, even if the loop condition has not become False or the sequence of...
In this chapter, we will learn about various flow control statements. What are the Flow Control Statements? A Flow Control Statement defines the flow of the execution of the Program. There are 7 different types of flow control statements available in Python: if-else Nested if-else for while ...
