expect while loop

A detailed description of Linux expect usageI. OverviewThrough the shell we can achieve simple control flow functions, such as: cycle, judgment and so on. But for situations where interaction needs to be done manually, we may sometimes need to

In shell development, when we connect to FTP or passwd or sudo, we need to enter the password manually. This is obviously inappropriate for automation. And expect's strong interaction model solves this problem. I am involved in this work, the

Every JS developer is inevitably dealing with the for loop. After all, this is one of the essential tools for traversing. However, when the number of cycles is large, the efficiency issue must be emphasized. The following article mainly introduces

Let's start with a test. What is the function of the following function? def foo (LST): a = 0 for i in LST: A + = i b = 1 for t in LST: b *= I return A, b If you think its function is to "compute the LST of all the

Several methods and efficiency Summary of for loop in JavaScript, javascriptfor Preface For the for loop, I believe it is not common. But this is because I didn't understand the meaning of a for loop when I read the code. This for loop is written as
