如何在python中的任意数组中将每个元素除以一个数字？

对Python非常陌生，我正尝试为工作中的经理制作一个小费计算器。

提示的计算方式是服务器一天工作的百分比，他们可以获取提示的百分比。例如，如果服务器1在当天的工作时间为30％，则他们将收到当天给出的30％的提示。

我一直在试图找出如何将数字（存储代码中的变量“ hourNum”）除以存储服务器工作时间的数组中的每个元素。这会让我获得服务器正常工作的一部分。

使用下面的代码，数学似乎无法正确计算或正确打印。

不幸的是，我一直无法在Stack Overflow上找到类似的问题。

下面随附的是源代码，问题在标题为“计算每天工作的服务器百分比”的最后一节中：

#get hours in the day
print('Enter how many hours were worked in the day: ')

hourNum = int(input())

#get tips for the day
print("Enter how much tips were earned (enter to the nearest whole dollar, do not use a dollar sign): ")

tipNum = int(input())


# creating an empty list 
lst = [] 
  

# number of elemetns as input 
serverNum = int(input("Enter number of servers that worked the day : ")) 
  

# iterating till the range 
print("Enter the number of hours each server worked (in order): ")

for i in range(0, serverNum): 
    ele = int(input()) 
  
    lst.append(ele) # adding the element 
      
print("You entered: ", lst) 


#calculate percent of day servers worked
n = 0
for i in range (0,serverNum):
    print (hourNum / lst[0 + n])
    n+1

任何提示或帮助将不胜感激:)

表达式hourNum / lst[i]应为100 * lst[i] / hourNum：该值表示每个服务器工作的工作日的小时数百分比（hourNum），再乘以100，以百分比表示。另外，为什么不打印最终百分比，为什么不将它们存储在列表中，以便程序记住它们呢？

#get hours in the day
hourNum = int(input('Enter how many hours were worked in the day: '))

#get tips for the day
tipNum = int(input("Enter how much tips were earned (enter to the nearest whole dollar, do not use a dollar sign): "))

# creating an empty list 
lst = [] 

# number of elemetns as input 
serverNum = int(input("Enter number of servers that worked the day: ")) 
  
# iterating till the range 
print("Enter the number of hours each server worked (in order): ")

for i in range(0, serverNum): 
    ele = int(input()) 
  
    lst.append(ele) # adding the element 
      
print("You entered:", lst) 


#calculate percent of day servers worked
lst_percents = []
for i in range (0,serverNum):
    lst_percents.append(round(100* lst[i] / hourNum))

print("The percent of day the servers worked:", lst_percents)

样本输入和输出：

Enter how many hours were worked in the day: 10
Enter how much tips were earned (enter to the nearest whole dollar, do not use a dollar sign): 100
Enter number of servers that worked the day: 4
Enter the number of hours each server worked (in order): 
1
2
4
5
You entered: [1, 2, 4, 5]
The percent of day the servers worked: [10, 20, 40, 50]

我将把有关每个服务器的提示的计算留给您。希望通过列出服务器工作天数的百分比会更容易。
