Now my problem is sleep function is not working properly. It print whole sentence after long delay. import sys from time import sleep words = "This is just a test :P" for char in words: sleep(0.5) sys.stdout.write(char) I use "sys.stdout.write" for removing whitespace between characters. 回答1: you should use sys.stdout.flush() after each iteration The problem is that stdout is flushed with the newline or

I have a function that returns a list though I am getting a warning in PyCharm. The warning reads: Class 'ABCMeta' does not define '__getitem__', so the '[]' operator cannot be used on its instances from typing import List def get_list() -> List[int]: return [1, 2, 3] Is anyone able to better interpret that message then I can? Thanks 回答1: Was a bug in PyCharm. Resolved in 5.0.3. REF: https://youtrack.jetbrains.com/issueMobile/PY-17841 文章来源: Python 3.5 Typing

What buttons do I have to press after typing in the comment, to get it to move to the next stage of actually committing? I'm using mysysGit on Windows with the default setup. 回答1: Depends on the text editor you are using. Git chooses the editor specified in the environment variable "EDITOR." On Linux systems this is usually either Vi or Nano. Figure out which it is and then refer to the documentation for the appropriate editor. 回答2: try this: git add file

EDIT: As per Andy's answer I know how I can go about it, but still curios how those guys wrote onpaste event. 回答1: Safari, Chrome, Firefox and Internet Explorer all support the onpaste event (not sure about Opera). Latch onto the onpaste event and you will be able to catch whenever something is pasted. Writing this is simple enough. Add the event handler to your input using html: <input type="text" id=

I wondered if there is a programming language which compiles to machine code/binary (not bytecode then executed by a VM, that's something completely different when considering typing) that features dynamic and/or weak typing, e.g: Think of a compiled language where: Variables don't need to be declared Variables can be created during runtime Functions can return values of different types Questions: Is there such a programming language? (Why) not? I think that a dynamically yet strong typed, compiled language would really sense, but is it possible? I believe Lisp fits that description. http://en

What I'd also like it to do is if it encounters a new line character in that string that it will "skip" the 3 words limit and put that in a new index and start adding words in that new index until it reaches 3 again. example var text = "this is some text that I'm typing here \n yes I really am" var array = text.split(magic) array == ["this is some", "text that I'm", "typing here", "yes I really", "am"] I've tried looking into regular expressions, but

Is it possible to change the text content in a loop with a typing effect, where it types out, then goes backward deleting the letters and starting all over with a new text? Is this possible with jquery? 回答1: Just a simple approach: $("[data-typer]").attr("data-typer", function(i, txt) { var $typer = $(this), tot = txt.length, pauseMax = 300, pauseMin = 60, ch = 0; (function typeIt() { if (ch > tot) return; $typer.text(txt.substring(0, ch++)); setTimeout(typeIt, ~~(Math.random() * (pauseMax - pauseMin + 1) +

For some languages this means that you as the programmer must specify what type each variable is (e.g.: Java, C, C++); other languages offer some form of type inference , the capability of the type system to deduce the type of a variable (e.g.: OCaml, Haskell, Scala,

(* Ed. note: Since this question was posted, the Wikipedia article has been edited to remove the word "dynamic".) It says about structural typing : A structural type system (or property-based type system) is a
