看下代码ex8.py
formatter = "%r %r %r %r" 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." )
你将看到下面结果
$ python ex8.py 1 2 3 4 'one' 'two' 'three' 'four' True False False True '%r %r %r %r' '%r %r %r %r' '%r %r %r %r' '%r %r %r %r' 'I had this thing.' 'That you could type up right.' "But it didn't sing." 'So I said goodnight.'
