编写一个程序读取未指定个数的字符串，找出出现次数最多的字符串并打印其出现次数。例如，输入abc bcd abc ddd
bbb，那么字符串abc出现的次数最多。
def Strcount(s): liststr=list(s.split()) #得到每个字符串，保存为列表 strcount={} #创建一个空字典
for i in liststr: #遍历list中的字符串 strcount[i]=liststr.count(i)
#统计出现的字符串个数，并写入字典strcount # print(strcount) item=[] #创建一个空列表 for k,v in strcount
.items(): #遍历strcount中的键值对 item.append([k,v]) #将遍历出来的键值对添加到item这个列表 item.sort(
key=lambda x:x[1],reverse=True) #对item列表以出现次数从高到低排序 #如果出现相同的，就都打印出来 print(
"出现次数最多的单词：") a=1 for i in range(len(item)-1): if item[i][1]==item[i+1][1]: a=a+
1 for i in range(a): print(item[i][0], "出现次数：", item[i][1]) if __name__==
"__main__": str = input("输入任意数量的字符串，用空格隔开\n") Strcount(str)
