表示可变数量的位置参数,它将传递给函数的所有位置参数都打包成一个元组(tuple)。在函数内部,可以通过遍历 args 元组来访问每个位置参数的值。 2)**kwargs 表示可变数量的关键字参数,它将传递给函数的所有关键字参数都打包成一个字典(dictionary)。在函数内部,可以通过字典的键来访问每个关键字参数的值 def my_...

同样,polar_to_cartesian 返回的“元组”(tuple类型)实际上并不是作为 Python 对象而创建的,而是临时表示为结构体(struct类型),然后由编译器对其进行优化。 GPU 所支持的 Python Numba 在 CPU 上受到限制无法编译所有函数,GPU 上同样如此。GPU 所支持的 Python 操作包括: if/elif/else while 和for 循环 基础...
min(x1, x2,...)The smallest of arguments. modf(x)The fractional and integer parts of x in a two-item tuple. Both parts have the same sign as x. The integer part is returned as a float. pow(x, y)The value of x**y.
