In this example, theis_primefunction checks if a number is prime by testing divisibility from 2 up to the square root of the number. Theprint_primesfunction iterates from 2 to N and prints the prime numbers. I executed the above Python code, and you can see the output in the screensho...

The latter range is based on the fact that a composite number must have a factor less than or equal to the square root of that number. Otherwise, the number is prime. You can change the value of variable num in the above source code to check whether a number is prime or not for ...
# simple.for.pyfornumberinrange(5):print(number) 在Python 程序中,当涉及创建序列时,range函数被广泛使用:您可以通过传递一个值来调用它,该值充当stop(从0开始计数),或者您可以传递两个值(start和stop),甚至三个值(start、stop和step)。看看以下示例: ...
