用于查找喜欢和不喜欢的数量的Python程序

Alice 和 Bob 列出了一个主题列表，他们都投票决定喜欢或不喜欢这个主题。他们写 0 表示不喜欢，写 1 表示喜欢。任务是计算他们都喜欢或不喜欢的主题数量。

例子：

Input: alice = “010101” bob = “101101”
Output: 3
alice and bob both like 4th and 6th topics and dislike the 5th topic. Hence, the output is 3.

Input: alice = “111111” bob = “000000”
Output: 0
There are no common likes or dislikes between alice and bob. Hence, the output is 0.

Input: alice = “110000” bob = “110011”
Output: 4
alice and bob both like 1st and 2nd topics and dislike 3rd and 4th topics. Hence, the result is 4.

编程需要懂一点英语

方法：

首先，我们必须遍历由 alice 的好恶组成的字符串的每个字符。
然后，我们必须将它与由 bob 的好恶组成的字符串的相应条目进行比较。
最后，我们将统计相似条目的数量并打印。

下面是实现。

# function to obtain no 
# of topics both alice and 
# bob like 
def commontopics(alice, bob):
      
    # initiate count with 0
    count = 0
      
    # iterating through alice
    for i in range(0,len(alice)):
          
        # comparing with corresponding
        # bob entry
        if alice[i] == bob[i]:
              
            # counting similar entries
            count += 1 
              
    # printing the count         
    print(count) 
  
#main function 
def main():
      
    commontopics("010101", "101101")
    commontopics("111111", "000000")
    commontopics("110000", "110011")
  
      
# driver code
if __name__ == "__main__":
    main()

输出：

3
0
4
