我放了他的.decode（＆＃34; utf-8＆＃34;）是不是？如果这是错的，请检查此代码，以便我需要把它放在哪里？

Answer 1

听起来像data_file是bytes object，而不是str。在这种情况下，.startsiwith需要一个字节参数（写为b'text'），而不是一个unicode字符串（写为'text'）。在这种情况下，你想要

 return data_file.strip().startswith(b'01BGMAX')

证明

b'hello world '.strip().startswith('hello')

# ---------------------------------------------------------------------------

# <ipython-input-38-cc253315406b> in <module>()
# ----> 1 b'hello world '.strip().startswith('hello')
# 
# TypeError: startswith first arg must be bytes or a tuple of bytes, not str


b'hello world '.strip().startswith(b'hello')
# True

Answer 2

字节文字以'b'开头。它创建一个字节类型的实例而不是字符串类型。您直接传递字符串时收到错误。尝试

return data_file.strip（）。startswith（b'01BGMAX'）

这将告诉python它是一个字节序列而不是Unicode字符

如何解决这个错误？
