Python的应用小案例

1.python统计文本中每个单词出现的次数：

#coding=utf-8
__author__ = 'zcg'

import collections
import os

with open('abc.txt') as file1:#打开文本文件
    str1=file1.read().split(' ')#将文章按照空格划分开

print "原文本:\n %s"% str1
print "\n各单词出现的次数：\n %s" % collections.Counter(str1)
print collections.Counter(str1)['a']#以字典的形式存储，每个字符对应的键值就是在文本中出现的次数

2.python编写生成序列化：

__author__ = 'zcg'
#endcoding utf-8
import  string,random

field=string.letters+string.digits

def getRandom():
    return "".join(random.sample(field,4))

def concatenate(group):
    return "-".join([getRandom() for i in range(group)])

def generate(n):
    return [concatenate(4) for i in range(n)]
if __name__ =='__main__':
    print generate(10)

3.遍历excel表格中的所有数据：

__author__ = 'Administrator'

import xlrd

workbook = xlrd.open_workbook('config.xlsx')
print "There are {} sheets in the workbook".format(workbook.nsheets)
for booksheet in workbook.sheets():
    for col in xrange(booksheet.ncols):
        for row in xrange(booksheet.nrows):
            value=booksheet.cell(row,col).value
            print value
其中xlrd需要百度下载导入这个模块到python中

4.将表格中的数据整理成lua类型的一个格式

#coding=utf-8
__author__ = 'zcg'
#2017  9/26

import xlrd
fileOutput = open('Configs.lua','w')

writeData="--@author:zcg\n\n\n"

workbook = xlrd.open_workbook('config.xlsx')
print "There are {} sheets in the workbook".format(workbook.nsheets)

for booksheet in workbook.sheets():
    writeData = writeData+'AT' +booksheet.name+' ={\n'
    for col in xrange(booksheet.ncols):
        for row in xrange(booksheet.nrows):
            value = booksheet.cell(row,col).value
            if row ==0:
                writeData = writeData+'\t'+'["'+value+'"]'+'='+'{'
            else:
                writeData=writeData+'"'+str(booksheet.cell(row,col).value)+'", '
        else:
            writeData=writeData+'},\n'
    else:
        writeData=writeData+'}\n\n'
else :
    fileOutput.write(writeData)
fileOutput.close()
