The break, continue and pass statements in Python will allow one to use for and while loops more efficiently.
#ESCAPE THE LOOP CODE#
The pass statement is helpful when a block of code is created but it’s no longer required. The preceding code does not execute any statement or code if the value of letter is ‘e’. continue is replaced with pass and a print statement. Here, we considered the above example with a small change i.e. Hence, pass statement can be used to write empty loops or can be used when a statement is required syntactically but you do not want any command or code to execute.Įxample of pass statement: for letter in 'CodeSpeedy': Unlike comment, interpreter does not ignore pass. In Python Programming, pass is a null statement. Hence, all the letters are printed except for ‘e’. The for loop skips ‘e’ every time it’s encountered but does not terminate the loop. Let’s consider the previous example with a small change i.e. Print('Loop terminated with the letter :',letter) Here, unlike break, the loop does not terminate but continues with the next iteration.Įxample of continue Statement: for letter in 'CodeSpeedy': When continue statement is encountered, current iteration of the code is skipped inside the loop. When a for loop is terminated by break, the loop control target keeps the current value.įor if-else condition, break statement terminates the nearest enclosing loop by skipping the optional else clause(if it has). After ‘S’ is encountered the loop is broke completely and the next statement after the for loop is executed which is “print(‘Loop terminated with the letter :’,letter)”.
In the above code, the alphabets are printed until an ‘S’ is encountered. Print('Loop terminated with the letter :',letter) In other words, when break is encountered the loop is terminated immediately.Įxample of break statement: for letter in 'CodeSpeedy': When break statement is encountered in the loop, the iteration of the current loop is terminated and next instructions are executed. Let’s look at them in detail in this tutorial. Loops are terminated when the conditions are not met.īut there are other ways to terminate a loop known as loop control statements. Loops are used when a set of instructions have to be repeated based on a condition. We can easily terminate a loop in Python using these below statementsĪ loop is a sequence of instructions that iterates based on specified boundaries.
#ESCAPE THE LOOP HOW TO#
In this tutorial, we will learn how to exit from a loop in Python with three different statements.
