I started out with “+”, then was told not to use it. So I listened and used “join”. Then later I used format. Now it seems that I should use “f”.
[code] f’{s} {t}’ # 78.2 ns s + ’ ’ + t # 104 ns ’ ‘.join((s, t)) # 135 ns ‘%s %s’ % (s, t) # 188 ns ‘{} {}’.format(s, t) # 283 ns Template(’$s $t’).substitute(s=s, t=t) # 898 ns [/code]
