Question

以下是在给定范围内打印素数的基本程序代码。我希望在列表中排列素数而不是每行打印一次。

lower = int(input("Enter lower range: "))
upper = int(input("Enter upper range: "))

print("Prime numbers between", lower, "and", upper, "are:")

for num in range(lower, upper + 1):
    if num > 1:
        for i in range(2, num):
            if (num % i) == 0:
                break
        else:
            print(num)

Answer 1

您应该附加到列表而不是打印数字：

lower = int(input("Enter lower range: "))
upper = int(input("Enter upper range: "))

print("Prime numbers between", lower, "and", upper, "are:")

prime_numbers = []

for num in range(lower, upper + 1):
    if num > 1:
        for i in range(2, num):
            if (num % i) == 0:
                break
        else:
            prime_numbers.append(num)

print(prime_numbers)

Answer 2

lower = int(input("Enter lower range: "))
upper = int(input("Enter upper range: "))
prime_list = list()
print("Prime numbers between", lower, "and", upper, "are:")

for num in range(lower, upper + 1):
    if num > 1:
        for i in range(2, num):
            if (num % i) == 0:
               break
        else:
            prime_list.append(num)
print(prime_list)

创建一个空列表prime_list = list()并将素数附加到该列表。最后打印列表print(prime_list)
