1、缩进
Tip
用4个空格来缩进代码
2、代码太长：
如果一个文本字符串在一行放不下, 可以使用圆括号来实现隐式行连接:
x = ('This will build a very long long '
'long long long long long long string')
或者：
print \\
"hello world!"
3、类：
class SampleClass(object):
4、注释：
"""Explicitly inherits from another class already.""" 或者 #Explicitly inherits from another class already.
5、字符串：
通常可以用+，%，join(), format 三个函数进行处理
%s #字符串
%d #数字
Yes: x = a + b
x = '%s, %s!' % (imperative, expletive)
x = '{}, {}!'.format(imperative, expletive)
x = 'name: %s; score: %d' % (name, n)
x = 'name: {}; score: {}'.format(name, n)
Join:
items = ['ni','hao'];
employee_table = ''.join(items);
6、处理文件：
1、with open("hello.txt") as hello_file:
for line in hello_file:
print line
2、import contextlib
with contextlib.closing(urllib.urlopen("http://www.python.org/")) as front_page:
for line in front_page:
print line
7、变量等命名规范：
