python版本使用的是2.7
工作中正好将正在学习的python用上，如果使用java写的话太麻烦，代码行数远比python要多。
第一个例子是根据id的列表生成insert语句插入到某个简单的表，因为需要做联合查询，所以新建一张一个字段的表，id安行存储在文件中：
import os
curdir = os.getcwd()
count = 0
sql = 'delete from test_userid;\ncommit;\n'
destFile = os.path.join(curdir,'mobile.sql')
with open(os.path.join(curdir,'mobile.dat')) as f:
for userid in f.readlines():
if userid == '\n':
continue
userid = userid.strip('\n')
sql += 'insert into test_userid values(\'' + userid + '\');\n'
count+=1
if count % 500 == 0:
sql+='commit;\n'
with open(destFile,'w') as fw:
fw.writelines(sql)
fw.close()
print 'convert success and the count is : %d' %count
每500行commit一次，涉及到了简单文件读写操作。
第二个例子是需要提取eclipse生成的.classpath文件中的classpath路径，用到了python的正则表达式：
import re
with open("D:\workspace\Client\.classpath") as f:
cpStr = ''
for line in f.readlines():
p = re.compile(r'.*kind="lib".*path="(.*?)"')
result = p.findall(line)
if len(result) > 0:
cpStr += p.findall(line)[0]
cpStr += ";"
print cpStr<?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src/main/java"/> <classpathentry kind="src" path="src/main/resources"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="lib" path="lib/thirdparty/dsf/protostuff-runtime-1.0.7.fixed.3300.jar"/> <classpathentry kind="lib" path="lib/thirdparty/dsf/xz-1.4.jar"/> <classpathentry kind="lib" path="lib/thirdparty/dsf/zookeeper-3.4.5.jar"/> <classpathentry kind="lib" path="lib/commonservice.api-V300R003C20B301-SNAPSHOT.jar"/> <classpathentry kind="output" path="classes"/> </classpath>
第三个小例子涉及到了GUI，说是界面其实是python中最简单的界面编程，使用的是TK，python自带的界面编程库：
# -*- coding: utf-8 -*-
#简单的日志排版工具，方便查看日志信息，定位问题
from Tkinter import *
#创建主窗口
win = Tk()
#创建输入文本框
textArea = Text(win)
textArea.pack()
#创建frame
frame = Frame(win)
frame.pack()
#指定button的父容器为frame
button = Button(frame,text='fomat')
button.pack(side=LEFT)
clearButton = Button(frame,text='clear')
clearButton.pack(side=RIGHT)
#创建结果文本框
textResult = Text(win)
textResult.pack(side=LEFT)
#创建滚动条
s = Scrollbar(win)
s.pack(side = RIGHT,fill = Y)
#绑定textResult和滚动条
textResult['yscrollcommand'] = s.set
s['command'] = textResult.yview
def formatText(e):
count = 0
flag = 0
#获取文本
content = textArea.get(0.0,END)
for i in range(len(content)):
text = content[i]
if text == ' ':
continue
if text == '[' or text == '{':
flag = 1
printBalnk(count, text)
count+=1
elif text == ']' or text == '}':
count-=1
printBalnk(count, text,0)
else:
printCommon(count,text,flag)
if text == ',':
flag = 1
else:
flag = 0
def printBalnk(count,text,flag=1):
textResult.insert(CURRENT,'\n')
for i in range(count):
textResult.insert(CURRENT,' ')
if flag == 1:
textResult.insert(CURRENT,text + '\n')
else:
textResult.insert(CURRENT,text)
def printCommon(count,text,flag):
if flag == 1:
for i in range(count):
textResult.insert(CURRENT, ' ')
textResult.insert(CURRENT,text)
if text == ',':
textResult.insert(CURRENT,'\n')
def selectText(e):
textResult.tag_add('select_all','1.0',END)
textResult.tag_config('select_all', foreground='red')
return 'break'
def clearSelectAll(e):
textResult.tag_config('select_all', foreground='black')
def clipboard(e):
content = textResult.get('1.0',END)
textResult.clipboard_clear()
textResult.clipboard_append(content)
def clearText(e):
textArea.delete(0.0, END)
textResult.delete(0.0, END)
button.bind('<Button-1>', formatText)
clearButton.bind('<Button-1>', clearText)
textResult.bind('<Control-Key-a>', selectText)
textResult.bind('<ButtonRelease-1>',clearSelectAll)
textResult.bind('<Control-Key-c>',clipboard)

一直在使用java编程，偶尔用用shell，python既有java强大的功能又有shell的简单，由于刚学python，虽说它是可以OO的，但是还是习惯当做一种脚本来写。
