红鲤鱼与绿鲤鱼与驴，到底几条鱼几头驴？计算出列表word = ["红","鲤","鱼","与","绿","鲤","鱼","与","驴"]有几条鱼几头驴。

新建一个字典输出结果，格式为：{'鱼': 2, '驴': 1}。

# 定义红鲤鱼与绿鲤鱼与驴列表
word = ["红","鲤","鱼","与","绿","鲤","鱼","与","驴"]
dic={}
num1 = 0
num2 = 0
item1 ="鱼"
item2 ="驴"
for item1 in word:
    num1 = num1 + item1
   
for item2 in word:
    num2 = num2 + item2

print(dic)
请问如果按照我这种思路写
应该怎么补全

你写的不对没法通过补全实现

改动最少的写法

1. word = ["红","鲤","鱼","与","绿","鲤","鱼","与","驴"]
   
2. dic={}
   
3. num1 = 0
   
4. num2 = 0
   
5. item1 ="鱼"
   
6. item2 ="驴"
   
7. 
   
8. for item in word:
   
9.     if item == item1:
   
10.         num1 = num1 + 1
    
11. dic[item1] = num1
    
12. 
    
13. for item in word:
    
14.     if item == item2:
    
15.         num2 = num2 + 1
    
16. dic[item2] = num2
    
17. 
    
18. print(dic)
