What if i want to read input from a file and show the output on the console itself rather than writing it to a output file?

I am familiar with this command.
python file.py < input.txt > output.txt
I want to take the input from file and show the output on the console itself as mentioned above.

It exactly doesn’t answer your question as I am a c++ enthusiast . If you ever use c++ . You can do it like this :
//use it just after int main()


and then proceed with normal procedure .

import sys
This will redirect the standard input stream to your file.Just include the above in your code and proceed normally.

At the risk of making a suggestion you best aussie writing services probably already know, I also want to point out that you don’t have to walk the journey alone. Having a strong and healthy support group, whether they be family, good friends, or counselors, can empower you along the way.
