Python输入一个字符串，统计每个字符出现的次数，并找出出现次数最多的字符

好的，可以使用Python中的字典来实现，代码如下：

string = input("请输入一个字符串：")
count_dict = {}
for char in string:
    if char in count_dict:
        count_dict[char] += 1
    else:
        count_dict[char] = 1

max_count = max(count_dict.values())
max_char = []
for key, value in count_dict.items():
    if value == max_count:
        max_char.append(key)

print("每个字符出现的次数：", count_dict)
print("出现次数最多的字符：", max_char)

输入一个字符串后，程序会输出每个字符出现的次数以及出现次数最多的字符。
