Loops
Explore the concepts of Python loops in this lesson. Understand definite and indefinite iterations, master the syntax of for and while loops, and learn how to control loop execution using break and continue statements. This lesson helps you write efficient, readable code essential for data science tasks.
We'll cover the following...
In a programming language, we sometimes need to execute statements x number of times. We don’t want to write the same programming statement x times, as doing so would make the code unreadable. Also, if we want to change something, we would have to change each block of code. That’s why looping is necessary.
Definite and indefinite iterations
Iteration can be definite or indefinite. Definite iterations are repeated a specific number of times, while indefinite iterations are repeated until a condition is met.Quiz: The importance of looping
Why is looping or iteration important in any programming language?
To determine the order of execution of statements
To create multiple paths of execution
To reduce execution time
To simplified code by removing redundant steps
While loop
A while loop iterates a block until the ...
