《笨办法学python3-Learn Python 3 the HARD WAY》-习题8 打印，打印

学习内容：

formatter = "{} {} {} {}"

print (formatter.format(1, 2, 3, 4))
print (formatter.format("one", "two", "three", "four"))
print (formatter.format(True, False, False, True))
print (formatter.format(formatter, formatter, formatter, formatter))
print (formatter.format(
    "Try you",
    "Own text here",
    "Maybe a poem",
    "Or a song about fear"
))

运行结果：

知识点：
print (formatter.format(1, 2, 3, 4))
变量定义时未给出具体内容只定义了｛｝，后面print (formatter.format(1, 2, 3, 4))格式化输出的内容为format(1, 2, 3, 4)括号内的内容。
