本文通过实例演示了Python中使用格式化字符串进行不同数据类型的打印操作。包括整数、字符串、布尔值及递归格式化的应用，展示了如何利用逗号简化长print语句。

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."
)

'''
Test Result:
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.'
'''

心得：

善用逗号，使得print语句变短，符合Python的编码风格
