python - 如何添加Python列表的所有元素

Question

所以基本上我有一个由用户输入的列表，我检查是否所有元素都是正数，我输出所有正数，如果它们都是负数，我输出所有负数，但如果它们都是正数和负数，我需要对它们求和一切都完成了，我不知道如何执行最后一步，这是我到目前为止的代码

stop = "0"
Numbers = []
number = ""
while number != stop:
    number  = input("enter a number ")
    Numbers.append(number)
    print(Numbers)
if all(int(element) >= 0 for element in Numbers):
    print("allpos")
if all(int(element) <= 0 for element in Numbers):
    print("all neg")

Answer 1

使用求和。

print(sum(numbers))

此外，变量名称请使用小写字符。

stop="0"
number =""
numbers=[]
while number != stop:
    number = input("enter a number ")
    numbers.append(int(number))
print(numbers)
if all(element > 0 for element in numbers):
    print("allpos")
elif all(element < 0 for element in numbers):
    print("all neg")
else:
    print(sum(numbers))

或更清晰的方法:

numbers = [int(x) for x in input("enter list of numbers, separated by space: ").split()]
print(numbers)
if all(element > 0 for element in numbers):
    print("allpos")
elif all(element < 0 for element in numbers):
    print("all neg")
else:
    print(sum(numbers))
