python-学习-打印

单引号和双引号：

formatter = "%r %r %r %r"

print formatter % (
    "I had this thing.",
    "That you could type up right.",
    "But it didn't sing.",
    "So I said goodnight."
)

打印结果为：

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

红色部分由于含有单引号，所以最外面的自动变成双引号
