在python中将unicode转换为字符串

Question

如何将 unicode 字符转换为文本？最好不导入任何库。输入是列表中的字符串。
样本输入：

\\u006A\\u0061\\u0064\\u0072\\u006F

预期输出：

jadro

(+ 最后不应该是字节类) 我正在翻译的列表：

保存翻译和损坏结果的代码：

f = open("dump.TXT","w+")
f.close()
f = open("dump.TXT","a")
for i in res:
    unic = i.split("'")[-2]
    trans = bytes(unic,"utf-8").decode('unicode-escape') + "\n"
    trans = trans.encode('utf-8').decode('utf8')
    f.write(trans)

完整代码：

import re

with open("org22.htm","r") as f:
    data = f.read()

start = "I = new Array();"
end = "State = new Array();"
s = data
array_r = s[s.find(start)+len(start):s.rfind(end)]
array_r = array_r.split("\n")
count, res = 0, []
for line in array_r:
    compare = "I["+str(count)+"][1][0][0] ="
    if compare in line:
            res.append(line)
            count += 1

    f.write(trans)

f.close()

Answer 1

不清楚您的输入是字节还是字符串。如果是字符串，可以转成字节，用unicode-escape解码：

s = "\\u006A\\u0061\\u0064\\u0072\\u006F"

bytes(s, 'utf-8').decode('unicode-escape')
# 'jadro'

如果它已经是字节，那么只需：

b = b"\\u006A\\u0061\\u0064\\u0072\\u006F"

b.decode('unicode-escape')
