spaces

Can anyone make the following run? public class ExecTest { public static void main(String[] args) { try { //Notice the multiple spaces in the argument String[] cmd = {"explorer.exe", "/select,\"C:\\New Folder\\file.txt\""}; //btw this works //String cmd = "explorer.exe /select,\"C:\\New Folder\\file.txt\""; //and surprisingly this doesn't work //String[] cmd = {"explorer.exe", "/select,\"C:\\New Folder\\file.txt\""}; //Update: and (as crazy as it seems) the following also worked //String[] cmd = {"explorer.exe", "/select,\"C:\\New", "Folder\\file.txt\""}; Runtime.getRuntime().exec(cmd); }

How do I strip all the spaces in a python string? For example, I want a string like strip my spaces to be turned into stripmyspaces , but I cannot seem to accomplish that with strip() : >>> 'strip my spaces'.strip() 'strip my spaces' Taking advantage of str.split's behavior with no sep parameter: >>> s = " \t foo \n bar " >>> "".join(s.split()) 'foobar' If you just want to remove spaces instead of all whitespace: >>> s.replace(" ", "") '\tfoo\nbar' Premature optimization Even though efficiency isn't the primary goal—writing clear code is—here are some initial timings: $ python -m timeit '""

I decided, that I learn a bit of Python. The first introduction says that it uses indentation to group statements. While the best habit is clearly to use just one of these what happens if I interchange them? How many spaces will be considered equal to one tab? Or will it fail to work at all if tabs and spaces are mixed? Jonathan Leffler Spaces are not treated as equivalent to tab. A line indented with a tab is at a different indentation from a line indented with 1, 2, 4 or 8 spaces. Proof by counter-example ( erroneous, or, at best, limited - tab != 4 spaces ): x = 1 if x == 1: ^Iprint "fff\n"
