main()
File "D:/word count2.py", line 6, in main
topTenWords(data)
File "D:/word count2.py", line 11, in topTenWords
Counter = Counter(split_it)
UnboundLocalError: local variable 'Counter' referenced before assignment
What is the mistake in above code? 上面的代码有什么错误?
You are overwriting the imported Counter Class with a variable. 您正在用变量覆盖导入的Counter类。 Just write for example
counter = Counter(split_it)
and it should work. 只需编写例如
counter = Counter(split_it)
,它应该可以工作。
Also just btw, you might wanna read the PEP8 Style Guide for Python, usually you don't use variable names that start with capital letters. 顺便说一句,您可能想阅读《 PEP8 Python样式指南》,通常您不使用以大写字母开头的变量名称。
this should works: 这应该工作:
# coding:utf-8
from collections import Counter
def main():
with open("../docs/words.txt", "r") as myfile:
data = myfile.read()
topTenWords(data)
def topTenWords(wordCountDict):
split_it = wordCountDict.split()
counter = Counter(split_it)
most_common = counter.most_common(10)
print(most_common)
if __name__ == '__main__':
main()
