59. sorted() returns sorted list from a given iterable 不改变原来的, 有返回值 和.sort()的两个不同点:# sort is a method of the list class and can only be used with lists Second, .sort() returns None and modifies the values in place (sort()仅是list的方法,它会改变替换原来的变量) ...
同样builtin_methods是一个PyMethodDef数组,以空PyMethodDef结尾。熟悉的print、dir等函数都可在这找到定义。 这类Moudle还有很多,如io模块也是这样实现的。在Modules\_io\_iomodule.c可找到对应的定义。 3.内存中的builtin_function_or_method Python提供了一个叫id的函数,该函数可以查看对应对象在内存中的地址。

B(Built-in):内置作用域,包含 Python 内置名称。 作用域的查找顺序:当访问一个变量时,Python 会按照LEGB顺序查找: 先在局部作用域(Local)中查找。 如果未找到,则在外层函数作用域(Enclosing)中查找。 如果仍未找到,则在全局作用域(Global)中查找。 如果仍未找到,则在内置作用域(Built-in)中查找。 如果仍未找到...
