你不能用电脑检测领带 max （据我所知），但你可以这样做：

# rewrote your dictionary creation as a one-line dict comprehension.

# I also renamed it, as I find calling a dictionary "values" to be very confusing,

# given that dictionaries have a method of the same name!

mydict = {str(i): int(i.count) for i in message.reactions}

# get the maximum value in the dictionary

max_val = max(my dict.values())

# get a list of all the keys that have the maximum value in the dictionary

highest_keys = [key for key, val in mydict.items() if val == max_val]

print(mydict)
print(highest_keys)
print(max_val)

如果您只想检测领带（并且对系的键不感兴趣），您可以这样做 sum(1 for val in mydict.values() if val == max_val) ，并测试该表达式的结果是否大于1。
