Python代码的执行由Python 虚拟机(也叫解释器主循环,CPython版本)来控制,Python在设计的时候,还没有多核处理器的概念,因此,Python 在设计之初为了设计方便与线程安全,就考虑到要在解释器的主循环中,同时只有一个线程在执行,即在任意时刻,只有一个线程在解释器中运行。对Python 虚拟机的访问由全局解释器锁(GIL)来控制...
float:浮点数包含整数和小数部分,如3.1415926,2.71828都属于浮点数; complex:复数包含实数部分和虚数部分,形如 a+bj,其实部和虚部都是浮点类型; 需要注意的是,Python3 已经废弃了 Python2 的 Long(长整型),在 Python3 中,int 的大小没有限制,可以作为 Long 使用。这也是为什么Python非常适合科学计算的原因,因为Py...
A note on Python range() and float values It is important to note that the range() function can only work when the specified value is an integer or a whole number. It does not support the float data type and the string data type. However, you can pass in both positive and negative ...
for i in range(1,4):for j in range(1,5):print('i*j',end='\t')这样子就是取3*4次，...
Python内置函数(27)——range 英文文档: range(stop) range(start,stop[,step]) Rather than being a function,rangeis actually an immutable sequence type, as documented inRangesandSequence Types — list, tuple, range. 根据传入的参数创建一个新的 range 对象...
Python内置函数(52)——range 英文文档: range(stop) range(start,stop[,step]) Rather than being a function,rangeis actually an immutable sequence type, as documented inRangesandSequence Types — list, tuple, range. 说明: 1. range函数用于生成一个range对象,range类型是一个表示整数范围的类型。
