# string mit Formatierung und Ersetzung wird als string in x gespeichert x = "There are %d types of people." % 10 binary = "binary" do_not = "don't" # wieder y = "Those who know %s and those who %s." % (binary, do_not) print x print y # %r mach das Ganze in raw print "I said: %r." % x print "I also said: '%s'." % y hilarious = False joke_evaluation = "Isn't that joke so funny?! %r" print joke_evaluation % hilarious w = "This is the left side of..." e = "a string with a right side." # Zusammensetzung von strings mit "+" # print "Schnick" + 3 geht NICHT, weil string und int print w + e
# 10 Punkte print "." * 10
# Format als string speichern formatter = "%r %r %r %r" # Format mit verschiedenem Inhalt mischen # Achtung: Geht nur mit %r, weil string, int (und float) print formatter % (1, 2, 3, 4) print formatter % ("one", "two", "three", "four") print formatter % (True, False, False, True) print formatter % (formatter, formatter, formatter, formatter) print formatter % ( "I had this thing.", "That you could type up right.", "But it didn't sing.", "So I said goodnight." )
