python - 如何摆脱python字符串中的b前缀？

Question

我有一个带有 b 前缀的字符串:

b'I posted a new photo to Facebook'

我收集 b 表示它是一个字节字符串。

如何删除这个 b 前缀？我试过了:

b'I posted a new photo to Facebook'.encode("utf-8").decode("utf-8")

但这会报错:

UnicodeEncodeError: 'charmap' codec can't encode characters in position 64-65: character maps to <undefined>

Answer 1

decode bytes 产生一个 str:

b = b'1234'
print(b.decode('utf-8'))  # '1234'
