# Write a program that prints all prime numbers from 0 to 1000

The while statement only affects the lines that are tabbed in a. If one exit from a loop is represented by a break, then all exits from the loop should be represented by breaks. If at any time, we get the remainder as zero, we conclude that the number is not prime.

First the program starts with a old list. For Loops[ edit ] The next type of loop in Python is the for loop.

The Current item is: The first line uses the range function. This is so that any duplicates get put next to each other. Sometimes you want to conditionally stop the loop in the middle of the loop body.

The program then initializes a prev ious variable. While loops[ edit ] This is our first control structure. If the remainder is zero, then the number is a factor. An easy way to do this is to write a program like this: We can further reduce this upper limit by noting that a number has no other factors except itself greater than sqrt n.

Thus, the loop body will normally iterate zero, one or more complete times. This will kill the program. If so, exit the loop with success. Often, you do indeed need to process all the numbers over a very wide range. If it is a duplicate was found.

The next question is what is the range of numbers we need to consider while checking if they are factors? We can do this by explicitly dealing with an iterator yielding the values to be checked. Note that this program could have been done in a shorter way: To do this, you can use the xrange function instead of range.

The first time the computer sees this statement, a is zero, and zero is less than 5. As a stylistic matter, it would be more consistent to follow this principle: Exercises[ edit ] Create a program to count by prime numbers. Next the program sorts the list.

The next line for count in onetoten: Supposing you were to write an expression like range 0, Next a for loop is gone into.Write a java program which prints all the prime numbers less than Arrays from ICS at King Fahd University of Petroleum & Minerals.
