问题 This question already has answers here : What do square brackets, “[]”, mean in function/class documentation? (4 answers) Closed 4 years ago . What is the meaning of the square brackets inside the round brackets of a function in the Python documentation? E.g.: help( [ object ] ) or int( [ x [ , base ]] ) 回答1: Everything that is in square brackets is optional, i.e. you can omit it. If the square brackets contain more than 1 argument, you can't choose which ones to omit, you must either specify

问题 Given a list of opponent seeds (for example seeds 1 to 16), I'm trying to write an algorithm that will result in the top seed playing the lowest seed in that round, the 2nd seed playing the 2nd-lowest seed, etc. Grouping 1 and 16, 2 and 15, etc. into "matches" is fairly easy, but I also need to make sure that the higher seed will play the lower seed in subsequent rounds. An example bracket with the correct placement: 1 vs 16 1 vs 8 8 vs 9 1 vs 4 4 vs 13 4 vs 5 5 vs 12 1 vs 2 2 vs 15 2 vs 7 7

问题 I've been searching up and down for an answer to this, but haven't found anything I can get to work. It may well be my lack of knowledge in the more "codey" aspects of Excel. Anyway, this is my situation: In C2-C17, I have some text set up like this:[2] Name of job. The "[2]" indicates the hours we expect the assignment to take, the rest is the name of the assignment. Now I need to calculate how many hours all this adds up to, so in B2-B17 (the numbers will change) I would like to extract the

问题 I'm writing a application to parse some commands. Commands are given in the form: A { B } I just want A and B. A is optional but that's easy enough to handle. The problem I'm having is that both A and B can contain almost any character including whitespace and '{' and '}'. The brackets need not be balanced, either. Is this possible to parse with a regex? If not, what is the simplest thing that you think could be done? For example, given: "parsme { foo { "hello" } { "goodbye" } {{{ } { bar {

问题 So I've been trying to get this code to compile using a gcc compiler using c (I found lots of references to c++ but none to c so I asked this) I kept on getting the error Badly placed ()'s every time I go to run the program.

问题 Sorry if I was not able to describe in the title how I like to do; I know that in AndroidStudio there is a way to use this brackets notation protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } instead this protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } In other words I like that the first bracket of any method, class etc starts a

问题 I've been given some CSV data I need to load into a PostgreSQL table with the following format: 7227, {text with, commas}, 10.0, 3.0, text with no commas I want my table rows to appear as: 7227 | text with, commas | 10.0 | 3.0 | text with no commas How can I use COPY and get it to ignore commas between the brackets? I'm trying to avoid pre-processing the file, although that is an option. 回答1: I'm afraid you'll have to edit the file. This format should be ok: 7227, "text with, commas", 10.0, 3
