[英]AttributeError: '_io.StringIO' object has no attribute 'StringIO'
I am looking for the solution to this error and I checked other similar questions but couldn't find an answer.我正在寻找此错误的解决方案,并检查了其他类似的问题,但找不到答案。 I am trying to implement Lempel-Ziv-1978 data compression algorithm and I have that error in my decompression function which is:
我正在尝试实现 Lempel-Ziv-1978 数据压缩算法,我在解压 function 时遇到了该错误:
def decompresser(stringAdecompresser): def 解压器(stringAdecompresser):
from io import StringIO
# creer la dictionnaire
size = 256
dictionnaire = {chr(i): i for i in range(size)}
resultat = StringIO()
w = chr(stringAdecompresser.pop(0))
resultat.write(w)
for k in stringAdecompresser:
if k in dictionnaire:
entree = dictionnaire[k]
else: # k == size:
entree = w + w[0]
resultat.write(entree)
#ajouter dans la dictionnaire
dictionnaire[size] = w + entree[0]
size += 1
w = entree
return resultat.StringIO()
and I got: File "lz78.py", line 52, in decompresser return resultat.StringIO() AttributeError: '_io.StringIO' object has no attribute 'StringIO'我得到:文件“lz78.py”,第 52 行,在解压缩器中返回 resultat.StringIO() AttributeError: '_io.StringIO' object 没有属性 'StringIO'
Python version: 3.6 Python 版本:3.6
Your resultat
is already a StringIO
.您的
resultat
已经是StringIO
。 Either return that, or, as @mechanical_meat suggests in his comment -- resultat.getvalue()
.要么返回,要么正如@mechanical_meat 在他的评论中建议的那样—— resultat.getvalue
resultat.getvalue()
。
