What is difference between while loop and for loop in Python?
for loops is used when you have definite itteration (the number of iterations is known). while loop is an indefinite itteration that is used when a loop repeats unkown number of times and end when some condition is met.
What is the difference between for loop while loop and repeat loop?
In the while loop, if condition is met, then it enters the loop and execute the code. But in the repeat loop ,it repeatedly executes the code inside the block until the stop condition is met.
When to use while loop?

Is a while loop or a for loop faster?
The while loop with decrements was approximately 1.5 times slower than the for loop. A loop using a callback function (like the standard forEach), was approximately 10 times slower than the for loop. Beside above, which loop is faster in C for or while? In C#, the For loop is slightly faster. For loop average about 2.95 to 3.02
Is a while loop always an indefinite loop?

What is while and for loop?
The for loop is a repetition control structure that allows the programmer to efficiently write a loop that needs to execute a specific number of times. The while loop is a repetition control structure that executes target statements as long as the given condition is true. The for loop can be used when the number of iterations is known.
