In the following example, we have two loops. The outerforloop iterates the first four numbers using therange()function, and the innerforloop also iterates the first four numbers. If theouter number and a current number of the inner loopare the same, then break the inner (nested) loop. ...

breakwill terminate the nearest encompassing loop, but this can get a little confusing when working with nested loops. It's important to remember thatbreakonly ends the inner-most loopwhen used in a script with multiple active loops. Let's consider the following example: ...
You can use abreak statementto implement the nested for loops. The break statement is one of the control statements which is used to terminate from the for loop/while loop. You can use a break statement in a nested loop to exit the innermost loop. In the following example, the outer for...
Nesting Python for loops When we have a for loop inside another for loop, it’s called a nested for loop. There are multiple applications of a nested for loop. Consider the list example above. The for loop prints out individual words from the list. But what if we want to print out th...
When break is used in for loop to terminate the loop before all the iterations are completed, the else block is ignored. Example: Python 1 2 3 4 5 6 for i in range(1,6): print(i) else: print("All iterations completed") Output: 1 2 3 4 5 All iterations completed Nested For ...
Nested Loops Breaking out of Loops Break Example Another Break Example Continue Continue Example Output Pass For Loops For loops in Python allow us to iterate over elements of a sequence, it is often used when you have a piece of code which you want to repeat “n” number of time. ...
Loops Inside LoopsA nested loop is a loop inside a loop.The "inner loop" will be executed one time for each iteration of the "outer loop":ExampleGet your own Python Server Print each adjective for every fruit: adj = ["red", "big", "tasty"]fruits = ["apple", "banana", "cherry"...
Nested loops use multiple loops inside one another. Although all of these looping patterns are supported by Python, we should be careful when using them.Because most loops are evaluated in a piece-by-piece manner, they are often inefficient solutions. ...
Repeat code multiple times using loops: write "for" and "while" loops; use "for" loops with range() and strings; write infinite "while" loops; apply nested loops; introduce "break" and "continue" instructions Write functions to make your code reusable: create functions with and without para...
