While a particularly difficult script might do some magic to explicitly read from the terminal rather than stdin, odds are you could just pipe to the script using bash pipeline syntax:

echo yes | python configure.py

or if you prefer, the "single command" version using bash here string syntax:

python configure.py <<

Lastly, if you need to provide multiple lines of input, probably the easiest approach is bash's heredoc syntax:

# Remove the single quotes if you need to do variable interpolation in the
# heredoc; the delimiter ENDOFINPUT is arbitrary, it just has to be used
# (with or without single quotes) after the `<<` operator, and w/o quotes
# at the end of the input to terminate the heredoc
python configure.py <<'ENDOFINPUT'
yes
