Python obtains the system iops sample code and pythoniops sample code.
Iops Overview
Iops is mainly used for data. This indicator is an important reference for database performance evaluation. iops refers to the number of read/write (I/O) operations per second, mainly depending on the random access performance, generally, disk arrays are used to increase iops. Th

In Python memory management, there is a block concept. It is more similar to the SGI sub-space Configurator.First, apply a large space (4KB) and cut it into a small portion (8, 161 until 512).When there is a request for memory, the simple process is to find the block according to the size, and then give it a copy on the Freeblock.

The attention method is used. there is an explanation on the internet. Simply put, a string of numbers is randomly generated, and then a subscript is used to determine whether these numbers are repeated. if they are repeated, a screening is performed.
The code is as follows:
Import randomPrint 'n' must> K else error'N = int (raw_input ("n = "))K = int (raw_input ("k = "))Result = []X = range (n)For I in range (k ):T = random. randint (I, n-1)Tem

No. 0007: There is a directory, which is your own written procedures, statistics on how many lines of code you have written. Include blank lines and comments, but be listed separately.
Train of thought: Get the directory, then traverse the directory of the code files, one by one to count each file code, and then the final summary of output.
