Python中不写满弦到文件(Python not writing full string to f

我试图输出对齐的蛋白序列到一个文件，但输出字符串每次我试图写入文件中的字符串时被截断。 我试图写的字符串是4603个字符，打印用正确的字符数的控制台。 代码的第一代码段我附加所属到输出变量本身。 我要在这里包括完整的字符串，因为在该字符串后写入文件截断的方式已经重现的我。

out=open('out.7.9.12.txt','a+')

score_dict={}
Max='1ZER'
al1='XMXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXDLDVXXXVNMXFVXXXIXXXXAXXGXXXXXXXXXXXXXXXXXXXGTLAIXXXXXXXPILAFVXAXXXXXXXXXXXSXXXXXXXXFLLXXXXXWPSXXXXXXXXXXXXXXXXXXXXALXXIRIYXYWYXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXWRRTXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLGMQVRYXXXXXXXXXXXXVHHXXEXDYQXFCYSXXXXXFRGXXRPXGXHXXKXXXPSILXXMLHXGXXXFSAHKDMWXXXXXXLSVXXXXXXXXXVXXKXFLPKNLXXXHLVCXXXXXXXXXXXXXXXXXXXXXXXVDXXXXXXXXXXXXXXXXXXXXXXMPXXGHXXXEXGTTRSXXXXXXXXXXSLXXXXDXXXXXXXXXXXXXXXXXXXXDLSIDGQXVKRIHQFXXXXXXXXXXXVXEXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXCXXLXKXLXNXXXXXXXXXXXXXXKXXXXXXXXXXXXXXXXXXXXXKXXXXXXXXXXXXXXXXXXXXXXXXPFXXXXXXXXXXXXXXXXXXXXXXHLVXXXGTSMGXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXGQXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXVXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXAXXGXXVYAAYYXXXXXXXXXXXXXXXXXXXXXXXPSDVSSLXXCLXVXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXCXXPXXXXXXXXXXXXXXXXXXAXXXXXGLXQXXXXYSXTDXXXNQFXXVXXXQRXXXXLXXXXXXXXXXXXXXXXXKXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXELQGXXXXXXXXXXXXXXXXXXXXSAXXXXXXXXXXXXXXXXXXXXXAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXVXXEKIXXXXPXXXXLIPSTPEXXEMSXEMLXXXXQXXLCXXXSXYXVXXXXXRFXKVPXQXXXXXXXXQIXLQXGXLVDVXXRXXIXPXXXHNXNXXFYRKXLXXXFLXXXXXXXXEIXVXSEXXXXXXKXXSXXXXXRYSXLXXXHXQNMXXXDKIXXXXXXXXXXKVXPTQXXIXXIWXXXXGXXXKQDXXXQVLXXDVXXXXSGADMLXXAKXXXSIAXNCQVXXEXXLXLEXXNCGXHSVVMEXRPRXXXKXTAKLXXIIDFLASVHNTDNNKKLDXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

score_dict[Max]=al1

for name,sequence in score_dict.items():
            out.write('>')
            out.write(name)
            out.write('\n')

            out.write('\n')

有了这个代码片段，输出到文件应该等于AL1。 但是，输出到文件内容如下：

粘贴这两个序列到文字处理器和计数的字符将显示在第一有4603个字符，第二个有4090个字符。

我在这里的顺序块道歉，但我不知道怎么回事，我可以准确地反映了这个问题。

编辑：该代码现在应该工作（我固定缓冲问题和报价问题）

Answer 1:

你关闭在最后的文件吗？ 这可能是一些数据的坐在缓冲，所以这是很好的关闭（）的文件，当你完成（或冲洗（） ，如果你不想关闭它由于某种原因）。

更重要的是，使用with结构，它会关闭你的文件，当你完成或发生异常：

with open('out.7.9.12.txt','a+') as out:
   # the rest of your code indented under here
   # ....
   score_dict={}
   Max=245

从注意的flush（）文档：

注意冲水（）不将文件数据不一定写入磁盘。 使用冲水（），其次是os.fsync（） ，以确保这一行为

Answer 2:

使用了out.flush（）末（或close（））来清除缓冲区。

Answer 3:

尝试把out.close()在脚本的结尾。 这将确保所有的输出被刷新到文件。

另外， 'A +' 是多余的; “a”是附加模式这已经是可写的。

Max = '245'
al1 = 'XMXXXXXXXXXXXXXXXXXXX ...'
scores = {Max:[al1]}

with open('out.7.9.12.txt', 'a') as outf:
    for name,data in scores.iteritems():
        outf.write('>{}\n{}\n'.format(name, '\n'.join(data)))

Answer 4:

我是有这个确切的问题。 我发现，我忘了叫接近的方法。 我用foo.close代替foo.close的（）。

这解决了它。
