In side the condition if which is optional predicate. This is the syntax of list comprehension. It sometimes happens to me too, in your case, the for y in range(2,int(x/2)+1) works as a normal for loop. However, you need comprehend it in order to utilize the list comprehension well. Coincidentally, list is just all about list comprehension. Your code written in for loop would be like this: for x in range(5,20):īecause any requires an iterable such as a generator expression or a **list** as mentioned above by. Your code is wrong because you inherit too much from the ordinary for loop. Both of the above approaches have a time complexity of O (n). As the only factor of n greater than n/2 is n itself, you may choose to run only up to n/2. If you don’t find a factor that divides n, then n is prime. You can simply understand that the loop comprehension already have the list of values, then they just simply feed orderly to the condition value by value. To check if a number is prime, the nave approach is to loop through all numbers in the range (2, n-1). A prime number is a number that is not evenly divisible by any other number (except, trivially, 1). Im trying to write this program that uses looping where it finds Brute Force Prime Nu,beds using Mersenne. First, we used For Loop to iterate a loop between 1 and 100 values. You may find out that the result of list comprehension is always a list, meanwhile the result of for loop would always many single values and these single values is a part of iterable Using Loop to find Brute Force Prime Numbers. This Python program prints the prime numbers from 1 to 100 using for loop and break. That is just the wonderful thing about list comprehension if it can work normally like the for loop, people wont create it because the for loop is more readable and understandable.
