Popularization of pci:
PCI (Peripheral Component Interconnect) is a bus standard that connects the motherboard of an electronic computer and external devices.
Common PCI cards include NICs, sound cards, modem, TV cards, and disk controllers, as well as USB and serial ports. The original video card is usually a PCI device, but soon its bandwidth is insufficient to support the performance of the video card. PCI graphics cards are currently only used when an additional ex

. This does not mean that no allocation operation is performed, but the counter is not updated because no collection occurs during this interval. Since we have learned that the time spent in garbage collection is an important factor, we will learn more about % time in GC later.
If you think you want to collect a large number of large objects (85,000 bytes or larger), you need to check the size of the large object heap (LOH. It is updated with allocated Bytes/sec at the same time.

We can create a list simply by creating a list, but with memory limitations, the list size is certainly limited. Also, creating a list of 1 million elements takes up a lot of storage space, and if we just need to access the first few elements, then the vast majority of the space behind it is wasted.
So, if the list element can be calculated according to an algorithm, can we continue to calculate the subsequent elements in the process of the loop? This eliminates the need to create a complete li

With a deep understanding of the Python Generator (Generator), we can simply create a list using the list generation method, but the list capacity is limited due to memory restrictions. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majority of elements is wasted.
Therefore, if the list elements can be calculated by some algorithm, can we continue to calculat
