问题 When I run a shell command in Python it does not show the output until the command is finished. the script that I run takes a few hours to finish and I'd like to see the progress while it is running. How can I have python run it and show the outputs in real-time? 回答1: Use the following function to run your code. In this example, I want to run an R script with two arguments. You can replace cmd with any other shell command. from subprocess import Popen, PIPE def run(command): process = Popen

问题 I am attempting to write an array of the first N primes to a txt file in rows of 5 entries each, with 10 spaces between each entry. The relevant code is as follows: #include<stdio.h> #include<math.h> #define N 1000 ... void writePrimesToFile(int p[N], char filename[80]) { int i; FILE *fp = fopen(filename, "w"); for(i = 0; i<=N-1; i++) { for(i = 0; i<5; i++) { fprintf(filename, "%10%i", p[i]); } printf("/n"); fclose(fp); } printf("Writing array of primes to file.\n"); } The compiler throws the

问题 I'm trying to use a command on everyfile .log in a folder but I can't understand how to change the output file for every file in the folder. #!/bin/bash N="0" for i in "*.log" do echo "Processing $f file..." cat $i | grep "test" | awk '/show/ {a = $1} !/show/{print a,$6}' > "log$N.txt" done How can i increment the counter for log$n.txt? 回答1: It's bad practice to write shell loops just to process text (see https://unix.stackexchange.com/questions/169716/why-is-using-a-shell-loop-to-process

问题 This question already has answers here : Division result is always zero [duplicate] (4 answers) Closed 5 years ago . I know you're usually not meant to put out all of your code but this is short and would help with the problem. Can anyone please explain why the output is 0 and how I can change the code to output what should be the volume of a cone. #include <stdio.h> float ConeVolume(int height, int radius); float ConeVolume(int height, int radius) { float pi; pi = 3.14159; float third; third

问题 If I simply copy and paste an HTML code provided by YouTube into a .Rmd file, this works fine for gitbook output. Here is an example of the code <iframe width="560" height="315" src="https://www.youtube.com/embed/9AI3BkKQhn0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen> </iframe> However, I get error messages for PDF and EPUB outputs.
