笨办法学python 习题8、9（format（）、三双引号和三单引号）

#format():
formatter="{}{}{}{}"

print(formatter.format(1,2,3,4))
#给参数赋值字符串
print(formatter.format("one", "two", "three", "four"))
#赋值为Ture 、Fales（python的关键字）  首字母要大写，不然报错
print(formatter.format(True,False,True,False))
#参数赋值
print(formatter.format(formatter, formatter, formatter, formatter))
# \n 换行
print(formatter.format(
    "if you miss the train I'm on\n",
    "You will know that i am gone\n",
    "You can hear the whistle blow a hundred\n",
    "A hundred miles,A hundred miles"
))
#三双引号或三单引号间的内容，保留原编码中的样式（排版布局）打印出来
#单引号括起来的字符串，字符串中间存在单引号时，通过\(反斜杠)进行转意
print('''
    if you miss the train I\'m on,
    You will know that i am gone,
    You can hear the whistle blow a hundred,
    A hundred miles,A hundred miles''')

小笨同学的总结，如有错误请各位大侠指点，谢谢。
