题目：
1.让你的脚本多打印一行；
2.让你的脚本只打印一行； 

3.在某行的起始位置放一个#(#)符号。

它的作用是什么？自己研究一下。

答案：

1、让你的脚本多打印一行：输出语句末尾增加”\n“

print "Hello World!\n"
print "Hello Again"
print "I like typing this."
print "This is fun."
print 'Yay! Printing.'
print "I'd much rather you 'not'."
print 'I "said" do not touch this.'

输出结果：

Hello World!

Hello Again
I like typing this.
This is fun.
Yay! Printing.
I'd much rather you 'not'.
I "said" do not touch this.

2、让你的脚本只打印一行：输出语句尾部增加“,”

print "Hello World!",
print "Hello Again",
print "I like typing this.",
print "This is fun.",
print 'Yay! Printing.',
print "I'd much rather you 'not'.",
print 'I "said" do not touch this.'

输出：Hello World! Hello Again I like typing this. This is fun. Yay! Printing. I'd much rather you 'not'. I "said" do not touch this.

3、在某行的起始位置放一个#(#)符号它的作用是什么？自己研究一下。
#号作用为注释作用，注释的语句不再输出

#print "Hello World!"
print "Hello Again"
print "I like typing this."
print "This is fun."
print 'Yay! Printing.'
print "I'd much rather you 'not'."
print 'I "said" do not touch this.'

输出结果：

Hello Again
I like typing this.
This is fun.
Yay! Printing.
I'd much rather you 'not'.
I "said" do not touch this.
