Unicode charactersare essential for encoding text in various languages and scripts, allowing for the representation of diverse writing systems. However, there are instances where we may need toremove Unicode characters from a string in Python, such as when working with data that requires ASCII encodi...
Python基础主要总结Python常用内置函数;Python独有的语法特性、关键词nonlocal,global等;内置数据结构包括:列表(list), 字典(dict), 集合(set), 元组(tuple) 以及相关的高级模块collections中的Counter,namedtuple,defaultdict,heapq模块。目前共有90个小例子。 1 求绝对值 绝对值或复数的模 >>>abs(-6)6 2 元素都...
This defines the data code which constraints elements in the array. They are represented in the below table. Table 1: Array Type codes Type CodePython typeC Type Minimum size in bytes ‘b’ int Signed char 1 ‘B’ int Unsigned char 1 ‘u’ Unicode character wchar_t 2 ‘h’ Int ...
Python defines Unicode as a string type that facilitates the representation of characters, enabling Python programs to handle a vast array of different characters. For example, any directory path or link address as a string. When we use such a string as a parameter to any function, there is ...
def encode_string(string): """Encode a string so that non printables are escaped. Returns unicode string. e.g. b"hello\x88xdr" -> "hello\x88xdr" """ byte_string = SmartStr(string) result = [] for c in byte_string: c = my_ord(c) if c > 127 or c < 32: result.extend("...
借助python的inspect模块:In [22]: for name,val in signature(f).parameters.items(): ...: print(name,val.kind) ...: a KEYWORD_ONLY b VAR_KEYWORD可看到参数a的类型为KEYWORD_ONLY,也就是仅仅为关键字参数。但是,如果f定义为:def f(a,*b): print(f'a:{a},b:{b}')...

53 + When you're at something like a 10B token dataset you end up needing around 5K for decent coverage. 54 + This is a signficant percentage of your normal, say, 32K bpe vocab. 55 + To avoid that, we want lookup tables between utf-8 bytes and unicode strings. 56 + And avoids ...
