这并不是Python的BUG,而是计算机在表示实际时普遍存在的问题。 6) 元组tuple 而说到不可变量,又会想起tuple,它在创建之后也是不可变的,那么它算不算不可变量呢? 它的数据类型确实属于不可变对象,可它的本质却和数组差不多,和c里的数组一样,每次创建都会分配内存空间。 我们想想,tuple真的永远不变吗?如果它其...
GIL的全称是Global Interpreter Lock(全局解释器锁),来源是python设计之初的考虑,为了数据安全所做的决定 在Python多线程下,每个线程的执行方式: 1.获取GIL 2.执行代码直到sleep或者是python虚拟机将其挂起。 3.释放GIL 可见,某个线程想要执行,必须先拿到GIL,我们可以把GIL看作是“通行证”,并且在一个python进程中,...

此错误一般是由于缩进不一致造成的。Python初学者100%会遇到此问题。 s = 0 for i in range(1, 6): s = s + i print( s) # 这里的缩进和上一行不一致 如果不理解缩进,可以参考理解Python的代码缩进 - 知乎 (zhihu.com)。 2.NameError: name 'xxx' is not defined ...

For the unpacking, by default a unique user temporary path one is used, and then deleted, however this default --onefile-tempdir-spec="{TEMP}/onefile_{PID}_{TIME}" can be overridden with a path specification, then using a cached path, avoiding repeated unpacking, e.g. with --onefile-te...

In Python, loops play a crucial role in interacting with various data structures. These structures, including lists, tuples, dictionaries, and sets, each have unique characteristics and are used for different purposes. Here's a brief overview of how loops are commonly used with these data struct...
