在numexpr 2 版本中,Unicode 数据类型(即 Python 3 中的 str 类型)是不被支持的。如果你尝试在 numexpr 表达式中使用 Unicode 字符串,将会遇到类似 numexpr 2 does not support unicode as a dtype 的错误。 3. 研究 numexpr 2 的文档或源代码,找出不支持 unicode 作为dtype 的原因 根据numexpr 的设计,它内...
And when you have a byte string, you need to decode it to use it as a regular(python 2.x) string. 所以,现在无论什么时候你有一个unicode str类但是你需要一个bytes类,你需要使用encode()函数转换它。 当你有一个bytes类型时,你需要用decode()函数转换它,作为一个普通unicode字符串。 Unicode string...
TypeError:'str' does not support the buffer interface 找问题找了好久,在StackOverflow上发现有人也出现同样的问题,并一个叫Scharron的人提出了解答: In python 3, bytes strings and unicodestrings are now two different types. Since sockets are not aware of string encodings, they are using raw bytes...
In Python, strings and bytes are distinct data types that serve different purposes. Strings (str) represent text data and are sequences of Unicode characters, while bytes (bytes) represent raw binary data and are sequences of byte values. The distinction becomes clear with the use of a b ...

翻译过来,也就是说在你使用python3的时候,如果想要使用套接字组件send发送str类型的东西,记得先encode()一下。同理,当你想用recv接受str东西的时候,记得decode()一下。 为什么会是这样呢? In python 3, bytes strings and unicodestrings are now two different types. Since sockets are not aware of string ...
