如何在for循环中将多个数字放在一行中

Question

for i in range(2, 101):if i > 1: # Prime numbers are greater than 1    for j in range(2, i):        if (i % j) == 0:            print(i,"is a composite number")            break        else:            print(i,"is a prime number")程序运行如下：2 is a prime number3 is a prime number4 is a composite number5 is a prime number6 is a composite number7 is a prime number8 is a composite number9 is a composite number10 is a composite number...我的问题是：我们如何将合数放在同一行而质数放在一行换句话说，如何做这样的事情：4,6... is all composite numbers和2,3,5... is all prime numbers

Answer 1

您可以将它们存储在列表中：

primes = []

composites = []

for i in range(2, 101):

    if i > 1: # Prime numbers are greater than 1

        for j in range(2, i):

            if (i % j) == 0:

                composites.append(i)

                break

        else:

            primes.append(i)

print("Composites: ", *composites)

print("Primes: ", *primes)

其中唯一花哨的部分是splat. 通过写 print("Composites: ", *composites)与*不带我们打印[]托架。

给出：

Composites:  4 6 8 9 10 12 14 15 16 18 20 21 22 24 25 26 27 28 30 32 33 34 35 36 38 39 40 42 44 45 46 48 49 50 51 52 54 55 56 57 58 60 62 63 64 65 66 68 69 70 72 74 75 76 77 78 80 81 82 84 85 86 87 88 90 91 92 93 94 95 96 98 99 100

Primes:  2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
