问题 I am using Mac OSX 10.10.5, and Python version 3.5.2, and IDLE version 3.5.2. I am extremely new to Python, and am trying to use the urllib3 module in IDLE. I have used the following code in the Terminal with success (the number 200 is returned): import urllib3 http = urllib3.PoolManager() r = http.request('GET', 'http://httpbin.org/robots.txt') r.status But the same code does not work in IDLE. In IDLE I get the following error: Traceback (most recent call last): File "/Users/faculty

问题 I'm trying to blur the bottom section of thousands (>50,000) of images using imagemagick. Image resolution is 800x600. The command line code (below) works, but takes a long time. Is there any way that this can be run in parallel, and hopefully called from within R using system()? I got this code off the internet, so I'm not sure if it's the best way to even achieve this objective? Any help would be greatly appreciated. Thanks in advance! (OS = OSX El Capitan) cd /Users/Desktop/test_images

问题 In an SO answer I wrote this code: char fail_on_eof (int c) { if (c == EOF) exit (EXIT_FAILURE); return (char) c; } void skip_to_next_line (void) { char c; do { c = fail_on_eof (getchar ()); } while (c != '\n'); } I was wondering whether there are any terminals that may return '\r' (which is covered by the above code as long as there is also a '\n' at end of line). Does stdin ever contain '\r' (on any platform)? What about input redirection is stdin always working in text mode? 回答1: Sure, it

问题 I recently updated my macbook to macOS Sierra (Version 10.12.3 (16D32)), and I am no longer able to run R directly from Terminal: DN51ssqi:~ kjytay$ R -bash: R: command not found DN51ssqi:~ kjytay$ R --version -bash: R: command not found Opening R from the Applications folder or from RStudio works fine.

问题 I would like to have some advice about how to port an old C++ program written for MS-DOS in the early 90s. This program implements a quite complex text-user interface. The interface code is well separated from the logic, and I don't think it would be too difficult to make it use ncurses. Being a complete novice, I have a few questions: The DOS program intercepts interrupt 0x33 to handle mouse events. The interrupt handler store events in a FIFO, which the main program pools periodically.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . What is the best way to remove all subfolders except ones with folder name X and Y using Terminal. 回答1: find . -mindepth 1 -d -type d ! -name X -a ! -name Y -exec rm -r {} \+ mkdir d; touch d/f; find . -name d -delete doesn't seem to work. -mindepth 1 and -d are optional at least on OS X.

问题 I have many files in my directory. It is very difficult to open one by one and see how many lines they have or how many columns they have.
