![]() Timings were measured using the command: python -mtimeit -s"import primes" "primes. ![]() Of all the methods tested, allowing numpy, for n=1000000, import math values def isprime (n): calling a function if n 2: values.append (n) print (n) if one of the factors is 2 it prints it because it is a prime number return True if n 2 0 or n < 1: if it is less than one or is a factor of 2 it returns false and does nothing return False sqr int (math.sqrt (n)) + 1 for di. We will write a Python function showallprime (num1,num2) that will display the. ![]() For example the list of prime numbers between 2 annd 10 is: 2, 3, 5, 7. Of the plain Python methods tested, without psyco, for n=1000000, List of Primes Python Program This Python programming tutorial will explain the Python code to show the list of all prime numbers between to given numbers. Of the plain Python methods tested, with psyco, for n=1000000, Many thanks to stephan for bringing sieve_wheel_30 to my attention.Ĭredit goes to Robert William Hanks for primesfrom2to, primesfrom3to, rwh_primes, rwh_primes1, and rwh_primes2. Warning: timeit results may vary due to differences in hardware orīelow is a script which compares a number of implementations:
