我需要编辑信息并使用以下格式返回每一行，并在“edgar”之前删除。

edgar/data/1000180/0001047469-15-003972.txt

Answer 1

这是一种不导入任何库的方法：

假设此数据存储在名为lines = [] with open('data.txt') as data: for line in data: lines.append(line.rstrip()) # rstrip() removes the newline character for i in range(len(lines)): lines[i] = 'edgar' + lines[i].split('edgar')[1]的文件中：

setwd()

Answer 2

这是另一个选项（Python 2.x或3.x）：

results = []

with open('file.txt') as f:
    for line in f:
        results.append(line.rstrip().split('|')[4]) # append to results the 4th element of the line
print(results)

这将循环遍历文件，在管道字符上拆分，然后取第4个元素（你想要的部分）。

它假定在名为file.txt的输入文件中。

Answer 3

这最终为我工作。

with open('file.txt') as f:
    data = str.splitlines(f.read())
    for eachLine in data:
        print(eachLine.split('|')[-1])

Python 3.4：编辑txt文件中的所有行
