Python 常用函数列表

日期 Date

from datetime import date
dt = date.date()
dt.year
dt.month
dt.day
day = str(dt.year) + '%02d' % dt.month + '%02d' % dt.day

随机数

import random
rd = random.random()

判断语句

if tree[0][0][0][i].tag == 'retCode' and tree[0][0][0][i].text == '0000':
	print 'is equal'
elif tree[0][0][0][i].tag == 'retCode':
	print 'is fail'
else:
	print 'is error'

FILE operation

fp = open(file)
line = fp.readline()
while line:
	line = fp.readline()

fp.close()

XML - ElementTree 操作

file2:

or XML is a string
