Sieve of Eratosthenes - Finding Primes Python 只是为了澄清,这不是一个功课问题:) 我想找到我正在建造的数学应用程序的素数并且遇到了Eratosthenes的Sieve方法。 我用Python编写了它的实现。 但它非常慢。 比方说,如果我想找到不到200万的所有素数。 大约需要20分钟。 (此时我停了下来)。 我怎样才能加快速度呢?
Here’s a small example showing some of what can be done. It’s a routine for finding prime numbers. You tell it how many primes you want, and it returns them as a Python list. 下面是一个显示可以用Cpython做的事情。一般都是找素数。你告诉程序你需要多少素数,然后它返回一个python列表。 ...
When working with small numbers, it is better and faster to use methods likeis_prime_1andis_prime_2, even with finding the next prime using something likenext_prime. However, when working with larger numbers, these simply do not work. They are memory and time heavy. The other algorithms ...
This code is shorter and more efficient than its equivalent for loop.Finding Prime NumbersAnother interesting example might be to extract all the prime numbers in a given interval. To do that, you can start by coding a predicate function that takes an integer as an argument and returns True ...
Finding maximum EVEN number: Here, we are going to implement a python program that will input N number and find the maximum EVEN number. By Anuj Singh Last updated : January 04, 2024 Problem statementWrite a Python program to input N integer numbers, and find the maximum even number....

Note: The above code isn’t the most efficient way to check for prime numbers. If you’re interested in digging deeper, then check out the Sieve of Eratosthenes and Sieve of Atkin for examples of more performant algorithms for finding prime numbers....
