WebI wrote a function to know whether a number is prime in Python (using Python 3.8.1 in this case). See is_prime_v1 below. Then I thought of trying a v2 by using the any built-in function, see is_prime_v2 below. I was curious to know the time difference between v1 and v2, and with the code below I get the following output on my computer: WebPython supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.. That's just an implementation detail, though — as long as you have …
