Passing input to python script invoked by shell script

Question

My shell script invokes a python script like this:

python take_user_input.py

The take_user_input.py script after getting invoked asks for user input, like this:

$ python take_user_input.py
Please enter your username: <expects user to enter username>
Please enter your email: <expects user to enter email>

It is not possible for me to modify the take_user_input.py script as it is part of another package.

Question: Is it possible to specify username and email in the shell script, such that it automatically takes those values after it invokes the python script?

You need a here document feature https://tldp.org/LDP/abs/html/here-docs.html — DYZ, Mar 16 '17 at 03:16

python take_user_input.py << EOF
me
me@email.com
EOF
