print "Hello world!---你好世界！"

# -*- coding: utf-8 -*-
print ("Hello world!---你好世界！")
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.")
# -*- coding: utf-8 -*-
这行用在脚本开头可以设定脚本编码格式

Tips：python 2.7与python 3.7的区别就是后者更加严格规范，必须带上括号！

python中使用（#）符号单行注释
