A binomial coefficient C(n, k) can be defined as the coefficient of X^k in the expansion of (1 + X)^n. A binomial coefficient C(n, k) also gives the number of ways, disregarding order, that k objects can be chosen from among n objects; more formally, the number of k-element ...

一个digit类型的数组ob_digit,用于存储整数值,数组长度默认为 1,在初始化时如果长度不够则会被扩大;digit是一个被PYLONG_BITS_IN_DIGIT宏控制的类型,在编译 Python 解释器时可以通过修改这个宏来指定其类型;如果没有指定PYLONG_BITS_IN_DIGIT宏的值,则默认会根据操作系统的类型来决定,当指针占用 8 字节以上空间...
Number(数字) String(字符串) List(列表) Dictonary(字典) Tuple(元组) sets(集合) 其中数字、字符串、元组是不可变的,列表、字典是可变的。 对不可变类型的变量重新赋值,实际上是重新创建一个不可变类型的对象,并将原来的变量重新指向新创建的对象(如果没有其他变量引用原有对象的话(即引用计数为0),原有对象...
