• %d: signed integer decimal
• %s: string
• %r: raw (for debugging)

# this line is tricky, try to get it exactly right
# Operationen in der Ersetzung möglich
# Ersetzung ist eine Liste (1, 'Schnack', a, b, a + b)

# string mit Formatierung und Ersetzung wird als string in x gespeichert

# wieder
y = "Those who know %s and those who %s." % (binary, do_not)

# %r mach das Ganze in raw

# 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)

    "That you could type up right.",
    "But it didn't sing.",
    "So I said goodnight."
