python - TypeError:强制转换为 Unicode:需要字符串或缓冲区

Question

此代码返回以下错误消息:

• open (infile, mode='r', buffering=-1) as in_f, open (outfile, mode='w', buffering=-1) as out_f: TypeError:强制转换为 Unicode:需要字符串或缓冲区，找到文件

  # Opens each file to read/modify
  infile=open('110331_HS1A_1_rtTA.result','r')
  outfile=open('2.txt','w')
  
  import re
  
  with open (infile, mode='r', buffering=-1) as in_f, open (outfile, mode='w', buffering=-1) as out_f:
      f = (i for i in in_f if i.rstrip())
      for line in f:
          _, k = line.split('\t',1)
          x = re.findall(r'^1..100\t([+-])chr(\d+):(\d+)\.\.(\d+).+$',k)
          if not x:
              continue
          out_f.write(' '.join(x[0]) + '\n')
  

请有人帮助我。

您尝试打开每个文件两次!首先你要做:

infile=open('110331_HS1A_1_rtTA.result','r')

然后你将 infile (这是一个文件对象)再次传递给 open 函数:

with open (infile, mode='r', buffering=-1)

open 当然希望它的第一个参数是文件名，而不是打开的文件!

只打开一次文件就可以了。
