I have just started coding and am stuck solving this python problem

问题

这是我迄今为止的代码：

  1. num = 0
  2. total_sum = 0
  4. while True:
  5.     number = float(input("请输入一个数字："))
  6.     
  7.     if number == -1:
  8.         break
  9.     
  10.     total_sum += number
  11.     num += 1
  13. if num > 0:
  14.     avg = total_sum / num
  15.     print("平均值是：", avg)
  16. else:
  17.     print("没有输入有效的数字，无法计算平均值。")

这段代码将一直要求用户输入数字，直到用户输入-1为止。然后，它将计算输入的数字的平均值（不包括-1），并将结果显示出来。

英文:

> Write a program that always asks the user to enter a number. When the user enters the negative number -1, the program should stop requesting the user to enter a number. The program must then calculate the average of the numbers entered excluding the -1.

This is what I have come up with so far

  1. num = int(input("How many number's are there?"))
  2. total_sum = 0
  4. avg = total_sum / num 
  6. for n in range (num):
  7.   number = float(input("Enter a number"))
  8. while number <0:
  9.   
  10.   print = ("Average is", avg)
  11.   
  12.  
  13. number >0
  14. print(number)
  15.   
  16. total_sum += number
  17.   
  18. avg = total_sum / num 
  19. print = ("Average is", avg)

I need it to stop at -1 one and still give an average of the numbers listed.

答案1

得分: -1

以下是代码部分的翻译：

  1. Easy.
  3. emp = []
  5. while True:
  6.     ques = int(input("Enter a number: "))
  7.     if ques != -1:
  8.         emp.append(ques)
  9.         continue # continue makes the code go back to beginning of the while loop
  10.     else:
  11.         if len(emp) != 0:
  12.             avg = sum(emp) / len(emp) # average is the sum of all elements in the list divided by the number of elements in said list
  13.             print(f"Average of all numbers entered is {avg}")
  14.             break
  15.         else:
  16.             print("Give me at least one number that's not -1")
  17.             continue # emp is empty we need at least one number to calculate the average so we go back to the beginning of the loop

希望这对你有所帮助。如果你有任何其他问题，或需要进一步的翻译，请随时告诉我。
