first 100 prime numbers python list comprehension

If you want it to return some other value (such as None) in that situation, you can pass it as a second argument to next. For the outer loop, I'd suggest using calling next on a generator, which gets the first value yielded by the generator: result = next(x for x in range(a, b+1) if all(x % y != 0 for y in range(2, int(x**0.5))))īy default next will raise StopIteration if the generator doesn't yield anything (because there are no primes between a and b). It can replace the inner loop, including the short-circuting behavior that came from the break and else blocks.

One way to turn this into a one-liner is to use the all builtin function. I think the logic you were attempting to show could work like this: def find_prime_between(a, b):

You have some current code, but what you've shown doesn't make any sense. Hope this post adds some value to your life – thank you.If I understand your intention correctly, you're trying to find the smallest prime between a and b in a single line. Print('sum of prime numbers',sum(prime_range(num= number))) Write a python program to create a list of prime numbers from 1 to N This is a bonus for the prime number program. num1 = int(input('Enter a first number: ')) #lower limitįrom all the above 6 programs we understand how to print prime number sequences. NOTE: In this program, we will change only the upper limit and lower limit of the while-loop with user input. write a python program to print prime numbers in a given range using a while loop Num2 = int(input('Enter a second number: ')) #upper limitĥ,7, 6. Source code: num1 = int(input('Enter a first number: ')) #lower limit NOTE: In this program, we will change only the upper limit and lower limit of the range() function with user input. write a python program to print prime numbers in a given range using a for loop Now we understand what is prime number and how to implement a prime number program in python so now it’s time to do it practically. Step-5: if i = j then print i ( Because i is your prime number) Step-4: step-3 implies that if a number i is not divisible by j then the program never enters in if-block, this means at the end of the second for-loop i = j

Step-3: check if i%j = 0 then break a loop (Because a number is not prime) Step-2: inside the first loop create another for loop in the range 2 to 100 –> for j in range(2,101) Step-1: iterate a for loop in range 2 to100 –> for i in range(2,101) Algorithm to Print Prime Numbers from 1 to 100 9 Write a python program to create a list of prime numbers from 1 to N What is a prime number?Ī natural number that is only divisible by 1 and itself is called a prime number.įor example: 2,3,5,7,11,13,17,19….
