Jul 23, 2024 · Looping until first 10 primes are not found: We can use a while loop to continue our prime check on the numbers until we print the first 10 prime numbers. Step-by-step algorithm: Maintain a variable cnt = 0 to keep track of number of primes printed so far. Maintain a variable num = 2 to keep track of the number to be checked for prime.

Oct 16, 2024 · Learn to print prime numbers from 1 to N in Python easily. Check other examples like print first 10 prime numbers in python using while loop, etc.

Nov 11, 2018 · Here's a Python implementation of a well-known algorithm (the Sieve of Eratosthenes) for generating the first n primes (credit to tech.io for the code): def sieve(n): primes = 2*[False] + (n-1)*[True] for i in range(2, int(n**0.5+1.5)): for j in range(i*i, n+1, i): primes[j] = False return [prime for prime, checked in enumerate(primes) if checked]

Step-1: iterate a for loop in range 2 to100 –> for i in range(2,101) Step-2: inside the first loop create another for loop in the range 2 to 100 –> for j in range(2,101) Step-3: check if i%j == 0 then break a loop (Because a number is not prime)

Write python programs to find prime numbers using for loop and while loop and also within a given range between 1 to 100.

Nov 3, 2022 · Let’s see the following program to print prime numbers from 1 to N (10, 100, 500, 1000, etc) using for loop, while loop: No = int(input(" Please Enter any Nober: ")) flag = 0. for i in range(2, (No//2 + 1)): if(No % i == 0): flag = flag + 1. break. if (flag == 0 and No != 1): print(" %d is a Prime Nober" %No) else:

Dec 20, 2021 · In this article, you will learn how to make python program to print prime numbers from 1 to n using for loop. print ("\n\n------The prime numbers from 1 to ", x, " are------\n\n") for i in range (x): # There are neither prime nor composite if as skip 0 …

# Program to check if a number is prime or not num = 29 # To take input from the user #num = int(input("Enter a number: ")) # define a flag variable flag = False if num == 0 or num == 1: print(num, "is not a prime number") elif num > 1: # check for factors for i in range(2, num): if (num % i) == 0: # if factor is found, set flag to True flag ...

In this tutorial, we’ve explored how to write a Python program to print prime numbers using a brute-force method. We’ve discussed the concept of prime numbers, implemented the program step by step, and tested it with examples.

Oct 8, 2024 · Algorithm to print prime numbers: First, take the number N as input. Then use a for loop to iterate the numbers from 1 to N; Then check for each number to be a prime number. If it is a prime number, print it. Approach 1: Print prime numbers using loop.
