Question

谁想帮助新手？我一直收到缩进错误，或者当我管理正确的缩进时，由于文件已经被打开方式自动关闭，所以我最终遇到了IO错误。我在做什么错了？

这是我的脚本；

 import csv

 infile = ('Test')

 with open(infile+'.txt') as csvfile, open('output.csv', 'w', encoding='utf-8') as outfile:
     lines = sorted(set(line.strip('\n').lower() for line in csvfile))
 for line in lines:
       writer = csv.writer(outfile, lineterminator='\n', quoting=csv.QUOTE_ALL)
            writer.writerow(line)

感谢您的帮助！

Answer 1

缩进代码以在with语句下写出。您那里还有一些空格，这些空格已排除掉缩进。我拼合了您的代码，然后缩进了代码。您可能必须先以读写方式打开，或者先打开一次才能读取，然后再打开一次即可。

import csv

infile = ('Test')

with open(infile+'.txt') as csvfile, open('output.csv', 'w', encoding='utf-8') as outfile:
    lines = sorted(set(line.strip('\n').lower() for line in csvfile))
    for line in lines:
        writer = csv.writer(outfile, lineterminator='\n', quoting=csv.QUOTE_ALL)
        writer.writerow(line)

我编辑了原始问题的格式。如果我的编辑没有以某种方式弄乱事情，则可能的问题是，通过在同一infile块中同时打开和关闭outfile和with，您已经在以下情况下关闭了outfile您要写它。

如果您这样重新排列它，则可能会更容易预测

import csv

infile = ('Test')

with open(infile+'.txt') as csvfile:
     lines = sorted(set(line.strip('\n').lower() for line in csvfile))

with open('output.csv', 'w', encoding='utf-8') as outfile:
    writer = csv.writer(outfile, lineterminator='\n', quoting=csv.QUOTE_ALL)
    for line in lines:
        writer.writerow(line)
