这是学习python的第7课，我学习到了python中更多种类的打印方法。1.print("." * 10） 是输出10个 "." , 把每个字母相加输出就可以得到相应的字符串。
print("Mary had a little lamb.")
print("Its fleece was white as {}." .format('snow')) #将snow放入字符串的相应位置
print("And everywhere that Mary went.")
print("." * 10) # what'd that do?
end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"
# watch that comma at the end. try removing it to see what happens
print(end1 + end2 + end3 + end4 + end5 + end6, end = ' ' ) # end = ' ' 为连接前后的成分，使其不换行
print(end7 + end8 + end9 + end10 + end11 + end12)
运行结果：
2.用了一个自定义的函数 formatter，其作用是：
<1>.取第1行定义的 formatter 字符串。
<2>.调用它的 format 函数,这相当于告诉它执行一个叫 format 的命令行命令。
<3>.给 format 传递4个参数，这些参数和 formatter 变量中的{}匹配，相当于将参数传递给了 format 这个命令。
<4>.在 formatter 上调用 format的结果是一个新字符串，其中的{}被4个变量替换掉了，这就是 print 现在打印出的结果。
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 your",
"Own text here",
"Maybe a poem",
"or a song about fear"
))
运行结果：
3.这个主要是讲定义的字符串可以直接打印出来，“n” 是换行符。
# Here's some new strange stuff, remember type it exactlyself.
days = "Mon Tue Wed Thu Fri Sat Sun"
months = "nJannFebnMarnAprnMaynJunnJulnAug"
print("Here are the days: ", days)
print("here are the months: ", months)
print("""
There's something going on here.
With the three double-quotes.
we'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
""")
运行结果：
