Learn to use for loop in Python to iterate over a sequence and iterable, such as a list, string, tuple, range. Implement fixed number of iterations using a for loop
We start off by initializing the value of depth to be equal to 5. Then using the outer for loop, we produce a list of numbers in descending order from 5 to 1. Inside the outer for loop, we set the value of n to be equal to i. After that, we start off the inner for loop usi...
如果send_command()从回显内容中读到了expect_string参数指定的内容,则send_command()依然返回完整的回显内容,如果没读到expect_string参数指定的内容,则netmiko同样会返回一个OSError: Search pattern never detected in send_command: xxxxx的异常,关于expect_string参数的用法会在稍后的实验里演示。
而使用赋值表达式时,我们可以改写为: if (match := pattern.search(data)) is not None: print(match.group(0)) 1. 2. 在if 语句中同时完成了求值、赋值变量、变量判断三步操作,再次简化了代码。 下面是在列表表达式中的用法: filtered_data = [y for x in data if (y := func(x)) is not None]...

Python subprocess was originally proposed and accepted for Python 2.4 as an alternative to using the os module. Some documented changes have happened as late as 3.8. The examples in this article were tested with Python 3.10.4, but you only need 3.8+ to follow along with this tutorial. Most...

Mode 2: For larger reductions, TorchInductor generates a loop using an entire block as an accumulator with a call to a Triton reduction at the end of the loop. Mode 3: For more complex operations (matmuls and convolutions), TorchInductor has its own template system for generating Triton co...
def grep(pattern, filenames): for f in filenames: for line in open(f): if pattern in line: print(line, end="") Both these programs have lot of code in common. It is hard to move the common part to a function. But with generators makes it possible to do it. def readfiles(...
