Python for循环处理多组数字求和技巧

total = 0
numbers = input("请输入一组数字（空格分隔）：").split()
for num in numbers:
    total += float(num)  # 使用float支持小数
print("总和为：", total)

n = int(input("请输入行数："))
total = 0
for _ in range(n):
    line_sum = sum(map(float, input().split()))
    total += line_sum
print("所有数字的总和为：", total)

total = 0
while True:
    user_input = input()
    if user_input == "":
        break
    for num in user_input.split():
        total += float(num)
print("总和为：", total)

lines = int(input("行数："))
total = 0
for _ in range(lines):
    nums = [float(x) for x in input().split()]
    total += sum(nums)
print("结果：", total)
