This answer doesn’t solve the problem, but it’s left here because 30+ people found it useful, otherwise I would have deleted it long time ago. Write to /proc/*pid of the program*/fd/0. The fd subdirectory contains the descriptors of all the opened files and file descriptor 0 is the standard input (1 is stdout and 2 … Read more
It depends on the environment that your JavaScript is executing in. In the browser, there is no standard input (the browser isn’t a console). The input would come generally from some textbox element in a form on the page. If you’re using something like Rhino, then you can import the standard Java I/O classes and … Read more
I need to input coordinates into an array until EOF is encountered, but something is wrong in my code. I used ctrl+Z, ctrl+D
Os You can list all files in the current directory using os.listdir: Glob Or you can list only some files, depending on the file pattern using the glob module: It doesn’t have to be the current directory you can list them in any path you want: Pipe Or you can even use the pipe as you specified using fileinput And … Read more
So you have used Python’s “pre built in functions”, presumably like this: This reads the file by invoking an iterator on the file object which happens to return the next line from the file. You could instead use: which reads the lines from the current file position into a list. Now, sys.stdin is just another file object, which happens … Read more
cat 1.txt – | ./game This cat is pointless, you could just as easily do this: ./game < 1.txt. Which can also be used to run the game under GDB: See also this answer.
here a concatenation solution:
You could use the fileinput module: fileinput will loop through all the lines in the input specified as file names given in command-line arguments, or the standard input if no arguments are provided. Note: line will contain a trailing newline; to remove it use line.rstrip()
I’m trying to do some of the code golf challenges, but they all require the input to be taken from stdin. How do I get that in Python?
For variable argument functions like printf and scanf, the arguments are promoted, for example, any smaller integer types are promoted to int, float is promoted to double. scanf takes parameters of pointers, so the promotion rule takes no effect. It must use %f for float* and %lf for double*. printf will never see a float … Read more
