Question

我正在尝试从文件中收集错误，我需要计算它们这是我需要的输出：[error1：6，error2：3，error3：2]

import os,sys
import collections
Data = []
errors = []
with open('out.txt') as f:
        for line in f:
            Data.append([word for word in line.strip().split("\t")])
for item in Data:
    try:
        date,error = item[0],item[5]
        errors.append(error.split('\n'))
    except IndexError:
        print "A line in the file doesn't have enough entries."

counter = collections.Counter(errors)
print counter

Answer 1

你写道：

errors.append(error.split('\n'))

现在error.split('\n') will **return a list**. As a result,错误不是字符串列表，而是字符串列表的列表。您可能希望将其替换为：

errors += error.split('\n')

现在errors将是一个字符串列表，字符串是可散列的项目。

错误：unhashable type ='list'
