What is the difference between a for loop and a while loop What are the similarities?
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..
What is the difference between for loop and while loop?
The ‘for’ loop used only when we already knew the number of iterations. The ‘while’ loop used only when the number of iteration are not exactly known. If the condition is not put up in ‘for’ loop, then loop iterates infinite times. If the condition is not put up in ‘while’ loop, it provides compilation error.
How does for loop and while loop differ in python and when do you choose to use them?
The for statement iterates through a collection or iterable object or generator function. The while statement simply loops until a condition is False. … If you don’t have a tidy data structure to iterate through, or you don’t have a generator function that drives your processing, you must use while.
What is while loop example?
Example 1: while loop When i is 1, the test expression i <= 5 is true. Hence, the body of the while loop is executed. ... Now, i is 2, the test expression i <= 5 is again true. The body of the while loop is executed again.
What is Loop example?
A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.
