如何获取列表中的索引
How to get index in list
我如何检查是否找到该值并打印语法?我已经完成了所有代码,但我的问题是我需要找到值在列表中的位置。问题出在代码的末尾。我在那些地方放了#blank,因为我不知道该放什么。
这是我的代码:
list_of_scores = []
count = 0
for i in range(10):
grade = int(input("Enter a quiz score "))
list_of_scores.append(grade)
for grade in list_of_scores:
while(count < 10):
print("The score at position[", count, "] = ", list_of_scores[count])
count = count + 1
search_value = (int(input("Enter a number to search for: ")))
***下面是我遇到问题的地方。我的代码的顶部应该是这样的:
while(count < len(list_of_scores)):
if(search_value) in list_of_scores:
print("The value of ", search_value, "is in the list at index",#blank)
else:
if search_value not in list_of_scores:
print(input("Sorry, this value isn't found. Please enter a new number:"))
print("The location of this value is: ", list_of_scores)
使用index()
获取列表中项目的索引
print("The value of ", search_value, "is in the list at index",list_of_scores.index(search_value))
