Multiline user input with list comprehension in Python 3

阅读更多关于 Multiline user input with list comprehension in Python 3

问题 Total newb to Python here. I'm working on CodeAbbey's problems using Python 3, and I'd like help to make the code for user input shorter. Let's say I want to get this input from the user: 3 2 3 4 5 6 7 First line is number of cases, and each of the following lines are the cases themselves with 2 parameters. I've figured out to do it in this way so far: N=int(input('How many cases will you calculate?\n')) print('Input parameters separated by spaces:') entr = [list(int(x) for x in input().split

What's the simplest way to return the first line of a multi-line string in Perl?

阅读更多关于 What's the simplest way to return the first line of a multi-line string in Perl?

问题 When I say simple, I mean, within an expression, so that I can stick it in as a value in a hash without preparing it first. I'll post my solution but I'm looking for a better one that reminds me less of VB. :) 回答1: How about ( split /\n/, $s )[0] ? You don't have to worry about \n being not cross-platform because Perl is clever enough to take care of that. 回答2: This isn't as simple as you like, but being simple just to be short shouldn't always be the goal. You can open a filehandle on a

Correct way to put long function calls on multiple lines

阅读更多关于 Correct way to put long function calls on multiple lines

问题 I have a long function, as seen below: hash_correct = hashlib.md5(salt + password)).digest().encode("base64") I'd like to split it up into two lines but am not sure of the correct way to do this in Python? Thanks. 回答1: The coding guidelines limiting length of lines is there, in part, to make the code more readable. In your case of chained method calls, the meaning is not clear. You should pick some temporary variable names for the intermediate values so that a reader of the code can

make nstextfield single line

阅读更多关于 make nstextfield single line

问题 how to make NSTextField really single line? I created a text field programmatically. when the return key is pressed, all text is selected. but I can still paste multiple lines of text. And when I press Arrow-right or Arrow down, it scroll to the next line. There aren't these issues if I use IB and set the "use single line mode", but I couldn't find the right method to set it programmatically. 回答1: Have you tried telling the field's cell to set whether it uses single-line mode? [myTextField

WPF Multiline TextBox for large content

阅读更多关于 WPF Multiline TextBox for large content

问题 In a WPF application, I want to build a "Find in Files" output pane, in which I can stream large quantity of text, without re-allocating memory at each line, like the TextBox would do. The WPF TextBox has a single Text property which stores a contiguous string. Each time, I want to add content, I need to do textBox.Text += "New Text" , which is bad. Ideally, that control would be virtual and require a minimum of resources, just for the visible lines. I thought about using a standard ListBox

Vim: multi-command for filtering out blocks of text

阅读更多关于 Vim: multi-command for filtering out blocks of text

This is a follow-up to my question about using multi-line regex in Vim . A quick explanation: I have blocks of text tagged with #tags and separated by a blank line. I want to filter out all blocks that include a specific tag. I was helped with regex here (thanks!), so I constructed the following command: command -nargs=1 TagSearch g/^$.\+\n$\{-}.*#<args>.*/y a | vnew | put a | %s/^#.*<args>.*\n/&\r Hence, doing a :TagSearch tag should: Search for the #tag , paste all corresponding Text Blocks into a new vertical buffer, Add a blank line between the Text Blocks in the new buffer. Q1 : When I
