python - Python-从二进制文件读取时如何删除 'b'？

Question

我有以下简单文件:

This Was Actually Written In Binary

By Suraj Vijay

我有以下代码:

file = open("test.dat","rb")
lines=list()
for line in file.readlines():
        lines.append(line.rstrip())
file.close()
print(lines)
print("File Reading Done")

这是我得到的输出:

 [b'This Was Actually Written In Binary', b'By Suraj Vijay']
 File Reading Done

但是我不希望每个字符串的开头都是'b'(即我希望输出如下):

  ['This Was Actually Written In Binary', 'By Suraj Vijay']
  File Reading Done

Answer 1

您只需解码“utf-8”中的行即可执行以下操作:

file = open("test.dat","rb")
lines=list()
for line in file.readlines():
        lines.append(line.rstrip().decode("utf-8"))
file.close()
print(lines)
print("File Reading Done")

之所以得到 b，是因为它已编码为utf-8，现在它是一个字节对象。

print(type(line))
<class 'bytes'>
