[英]difference between {str} and {str_} in Python
I am trying to debug a code in Python. 我正在尝试用Python调试代码。 When I go to debug mode and look at the variable word
in a similar code that works fine, I see the type of this variable is shown as {str}
, but in the other code that does not work correctly I see the type of word
in the debugger is shown as {str_}
. 当我进入调试模式并查看类似代码中的变量word
工作正常时,我看到此变量的类型显示为{str}
,但在其他代码中无法正常工作我看到了word
的类型在调试器中显示为{str_}
。 What is the difference between these and how can I convert a variable type {str_}
to a type {str}
. 它们之间有什么区别?如何将变量类型{str_}
转换为类型{str}
。
Here is part of the code: 以下是代码的一部分:
cv = CountVectorizer(min_df=1, charset_error="ignore", stop_words="english", max_features=200)
counts = cv.fit_transform([text]).toarray().ravel()
words = np.array(cv.get_feature_names())
...
for word, count in zip(words, counts):
I use PyCharm to debug, and it is in Python 3.3. 我使用PyCharm进行调试,它在Python 3.3中。
I appreciate any help on this. 我很感激任何帮助。
str
is probably the builtin str
. str
可能是内置的str
。 str_
is something else. str_
是别的东西。 Perhaps a subclass of str
? 也许是str
的子类? Hard to tell without seeing more 很难说没有看到更多
Edit: 编辑:
Looks like str_
may be numpy.str_
which is what you'll get if you pour a list of str into a numpy array 看起来str_
可能是numpy.str_
,如果你把一个str列表放到一个numpy数组中你会得到的
