关于python的各种问题，实在不知道叫什么了

Question

最近用狗屁不通文章生成器生成了一个1000字文章。 然后用python进行了一个简单的总结，代码如下：

from typing import Counter


url = "****.txt"
with open(url, 'r', encoding="utf-8") as file:
    file = file.read()
    counterResult = Counter(file)
    for letter, repeatTimes in counterResult:
        print(f"{letter} {repeatTimes}")

# 报错：
# Traceback (most recent call last):
# File "****************************************", line 8, in <module>
#      for letter, repeatTimes in counterResult:
# ValueError: not enough values to unpack (expected 2, got 1)
