Manually reading multiple lines of input in terminal

Question

I am writing a python code for a class which needs multiple lines of inputs.

For example I need the input to be in the format:

When entering this manually on the terminal, I do not know how to signal an end of input.

I have been working around it by entering the inputs in txt files and reading these.

What code are you using to read this? A standard approach is to use a specific string (that isn't an otherwise valid input) to tell your code to stop reading. (For example, early text editors in insert mode would read lines of input until you entered a single . as a line.) — chepner

On Linux, use Ctrl+D to type "end of file". On Windows, use Ctrl+Z.

Besides the control-d, in bash, you can also:

pythonscript <<EOF
3 14
12 10
12 5
10 5
EOF

On linux and unix you can find what the EOF char is using

stty -a

it will show something like

...
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <under>;
...

indicating the eof is ^D, which you can also change using stty.

Then, you can type ^D to signal EOF to a process that's reading its input from the terminal.
