It's a weird scenario I came across and I'm quite confused

$ printf "%s:%s\n" "$(date)" "$(python -V)"
Python 2.7.10

Whereas with other commands I get an expected result

$ printf "%s:%s\n" "$(date)" "$(hostname)"

python -V prints to stderr. Use 2>&1 to redirect the output to stdout so it can be captured.

$ printf "%s:%s\n" "$(date)" "$(python -V 2>&1)"
