参照着php版的接口写的

目前测试使用没问题,预留了保存cookie和token的功能,可以减少几次请求,以后慢慢加吧!

目前给自己发通知还是妥妥的。

调试程序的时候,如果需要打印出变量的信息,在python中很容易,一句print即可,他几乎可以打印任何类型的对象,不像PHP中,有一堆echo(),print(),print_r(),var_dump(),让人头疼!

但是PHP的打印函数有个好处,就是打印格式良好,而Python的打印信息就不是很友好了,如

# 模拟一个很大的键值对
dic = {}
for i in xrange(201):
    dic[i] = "value for %d" % i
print dic

其结果我就不打印了,总之很难看!

如何让python那冗长而且没有格式的打印变得更直观,方法有两种。

自定义dump

此方法来自stackoverflow


# 以后需要有格式的打印一个集合对象,直接使用dump(xxx)即可!
# 不要忘了import sys
import sys

def dump(obj, nested_level=0, output=sys.stdout):
    spacing = '   '
    if type(obj) == dict:
        print >> output, '%s{' % ((nested_level) * spacing)
        for k, v in obj.items():
            if hasattr(v, '__iter__'):
                print >> output, '%s%s:' % ((nested_level + 1) * spacing, k)
                dump(v, nested_level + 1, output)
            else:
                print >> output, '%s%s: %s' % ((nested_level + 1) * spacing, k, v)
        print >> output, '%s}' % (nested_level * spacing)
    elif type(obj) == list:
        print >> output, '%s[' % ((nested_level) * spacing)
        for v in obj:
            if hasattr(v, '__iter__'):
                dump(v, nested_level + 1, output)
            else:
                print >> output, '%s%s' % ((nested_level + 1) * spacing, v)
        print >> output, '%s]' % ((nested_level) * spacing)
    else:
        print >> output, '%s%s' % (nested_level * spacing, obj)

pprint

此方法来自官方,可以自定义缩进,宽度等信息。

import pprint

dic = {}
for i in xrange(201):
    dic[i] = "value for %d" % i

# 自定义缩进为4空格
pp = pprint.PrettyPrinter(indent=4)
pp.pprint(dic)

老高推荐官方的pprint,自定义格式很不错!

家里的宽带是包年按天扣费,时间长了就忘了改什么时候续费了。

抽时间写了个模拟登录10010.com的脚本,自动查询余额。

每天中午12点查一次,省得下次又欠费了。

模拟登录的过程很简单,获取查询的cookie需要两步请求,拿到cookie后可以随意查询。

有TX想看源码么?

数据拿到了剩下的问题就是如果发送到手机了,老高前几天写了个飞信发送短信脚本,中国移动的用户有福了。

python在用命令行的时候能够接受很多参数,到底是如何接受那些参数和选项呢?


import sys, getopt

opts, args = getopt.getopt(sys.argv[1:], "hi:o:")
input_file=""
output_file=""
 
for op, value in opts:
    if op == "-i":
        input_file = value
    elif op == "-o":
        output_file = value
    elif op == "-h":
        usage()
        sys.exit()

进入File->settings->Editor->File and Code Templates->Python Script

添加以下内容:

#!/usr/bin/env python
# encoding: utf-8

#set( $SITE = "http://www.phpgao.com" )

def func():
    pass


class Main():
    def __init__(self):
        pass


if __name__ == '__main__':
    pass

脚本中还可以添加自定义变量!
