How for loop is executed in Python?
The Python for statement iterates over the members of a sequence in order, executing the block each time. Contrast the for statement with the ”while” loop, used when a condition needs to be checked each iteration, or to repeat a block of code forever. For example: For loop from 0 to 2, therefore running 3 times.
How to execute a for loop in Python?
With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. The for loop does not require an indexing variable to set beforehand. With the break statement we can stop the loop before it has looped through all the items:
How does a WHILE LOOP statement work in Python?
A while loop statement in Python programming language repeatedly executes a target statement as long as a given condition is true. The syntax of a while loop in Python programming language is Here, statement (s) may be a single statement or a block of statements with uniform indent.
When to skip statement in for loop in Python?
We can skip the execution of further statements in the for loop body, during that iteration, using continue statement. When continue statement is executed, the for loop continues with the execution of next element in the iterable, rather than completing all the statements in the for loop body.
Which is the continuation statement in Python for loop?
As you see from the above output, it sequence started from the start-value (which is 4), and then increment the next number by the increment-value (which is -2), and keeps going all the way through end-value-1. 7. Continue Statement Inside Python For Loop You can use “continue” statement inside python for loop.
How does a for loop work in Python?
When program execution enters for loop for the first time, it checks if there is an item from iterable. If an item is available, the program executes statement (s) inside for block. After execution of the statement (s), the program checks if there is next item available. If True, then the statement (s) are executed again for this next item.
We can skip the execution of further statements in the for loop body, during that iteration, using continue statement. When continue statement is executed, the for loop continues with the execution of next element in the iterable, rather than completing all the statements in the for loop body.
When to execute the else statement in Python?
Python supports to have an else statement associated with a loop statements. If the else statement is used with a for loop, the else statement is executed when the loop has exhausted iterating the list. If the else statement is used with a while loop, the else statement is executed when the condition becomes false.
What happens after print statement in for loop in Python?
The print statement after the continue statement in the for loop has been skipped and continued with the next element in the loop, which is 8. Just like in an if-else statement, you can use an else block with for loop. This else block is executed after the for loop is completed with all the elements in the iterable.
