Difference between for loop and while loop any one can explain

Answer 1

Prakash Check this out:
Loops: while and for
• https://javascript.info/while-for

for (let i = 0; i < 10; i++) {
    // do something
}
for loop consists of three statements, one that is executed before our loop starts (i = 0), one that defines how long our loop should run (i < 10), and one that is executed after each loop (i++).

In this example, we are setting i = 0 before our loop starts. We will continue to loop as long as i < 10, and each iteration of the loop will increase i by one. Finally, within our brackets is the code that will be run on each iteration of the loop.

Any part of 'for' can be skipped.
For example, we can omit 'begin' if we don’t need to do anything at the loop start.

let i = 0; // we have i already declared and assigned

for ( ; i < 3; i++) { // no need for "begin"
    console.log(i); // 0, 1, 2
}

We can also remove the 'step' part:
let i = 0;
for ( ; i < 3; ) {
    console.log(i++);
}

The loop became identical to while (i < 3).

Loop Better: a deeper look at iteration in Python

Answer 3

for-loop allows locally scoped variables, while-loop doesn't,

Python's for-loop is somewhat like for-each loop in the 3 other tagged languages.

Answer 4

#The for statement iterates through a collection or iterable object or generator function.
In for loop we can define the how many time will the for loop run.
For loop is easy to write than while loop because in for loop initialization,condition check,increment/decrement define in one line.

#The while statement simply loops until a condition is False.in while loop we check only condition if condition become false then loop break otherwise it will run.variable is define before outside from the loop and it increment/decrement inside the loop.

Also check this.

Answer 5

FOR LOOP checks the conditions before iteration.
WHILE LOOP iterates some part of codes before checking the conditions.

Answer 6

Simple:
"A condition-controlled loop causes a statement or set of statements to repeat as long as a condition is true. IN PYTHON, you use the WHILE statement to write a condition-controlled loop."
"A count-controlled loop iterates a specific number of times. IN PYTHON, you use the FOR statement to write a count-controlled loop."
