Whilequeuelibandpython-pqueuecannot fulfil all of above. After some try, I found it’s hard to achieve based on their current implementation without huge code change. this is the motivation to start this project.

Method 1: Read From stdin Using sys.stdin Thesysmodule contains astdinmethod for reading from standard input. Use this method to fetch user input from the command line. Import thesyslibrary and use thestdinmethod in afor loop. See the example below for a demonstration: ...
For executing the Python files, you must use the terminal. Moreover, the errorFile "<stdin>", line 1, in <module>can also be written asFile "<stdin>", line 6, in <module>depending on the line number on which the error is encountered but the meaning of the error and the way to ...
So be sure to test your code thoroughly if you plan to use this method. 6. Summary and Conclusion We have explained how to read from stdin in Python, Stdin is short for Standard Input. You have learned how to use input() function and other methods along that to read from stdin. I ...
2. Using input() function to read stdin data We can also usePython input() functionto read the standard input data. We can also prompt a message to the user. Here is a simple example to read and process the standard input message in the infinite loop, unless the user enters the Exit...
