查找特定整数的出现次数

Question

我一直在第9行得到一个关键词，我不能为我的生活弄清楚。

这是我的代码

numbers = (input("Enter numbers separated by spaces > "))
alist = []
alist = numbers.split()
count = {}
for word in alist:
    if word not in alist:
        (count[word]) = 1
    else:
        (count[word]) = (count[word]) + 1
print(count)
for k,v in count.item():
    if v == 1:
        print(k, "occurs", v, "time")
    else:
        print(k, "occurs", v, "times")

Answer 1

word not in alist始终为false，因为for循环遍历alist。

替换以下行：

if word not in alist:

与

if word not in count:

顺便说一句，你不需要围绕count[word]的括号。
