在Python中计算用户输入的数字[重复]

Question

所以我的问题是这个程序应该接受输入的数字（例如

5

）将是

0+1+2+3+4

并且总和将是

10

。我已经得到它来列出这些数字，但我如何使这个代码来计算它们？

num1 = int(input("How many laps?: "))
num2 = int(0)

for lap in range (num1):
   num2 = lap
   print("Sum is:" , (num2))

Answer 1

简单的解决方案如下

num1 = int(input("How many laps?: "))
print(sum(range(num1)))

Answer 2

像你尝试的那样用循环来做

num1 = int(input("How many laps?: "))

list = []

for lap in range (num1):
   list.append(lap)

listSum = sum(list)

print(listSum)
