文件内容如下,文件编码为utf-8:
cd232704-a46f-3d9d-97f6-67edb897d65f b'this Friday, Gerda Scheuers will be excited \xe2\x80\x94 but she\xe2\x80\x99s most excited about the merchandise the movie will bring.'
这是我的代码:
with open(file, 'r') as f_in:
for line in f_in:
tokens = line.split('\t')
print(tokens[1])
我想得到正确答案 - "本周五,Gerda Scheuers会很兴奋 - 但她对电影带来的商品最为兴奋。"
print(b'\xe2\x80\x94'.decode('utf-8')) #convert into ASCII
但我无法从文件中读取字节。如果我打开一个包含字节的文件,我需要对该行进行解码以进行分割。
答案 0 :(得分:2)
您可以使用ast.literal_eval
将字节文字转换为字节:
然后,解码它以获取字符串对象:
>>> ast.literal_eval(r"b'excited \xe2\x80\x94 but she\xe2\x80\x99s'")
b'excited \xe2\x80\x94 but she\xe2\x80\x99s'
>>> ast.literal_eval(r"b'excited \xe2\x80\x94 but she\xe2\x80\x99s'").decode('utf-8')
'excited — but she’s'
with open(file, 'r') as f_in:
for line in f_in:
tokens = line.split('\t')
# if len(tokens) < 2:
# continue
bytes_part = ast.literal_eval(tokens[1])
s = bytes_part.decode('utf-8') # Decode the bytes to convert to a string
