Python中应用的小案例分享

#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:
 %s"% str1
print "
各单词出现的次数：
 %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

__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

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

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

writeData="--@author:zcg


"

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+' ={
'
 for col in xrange(booksheet.ncols):
 for row in xrange(booksheet.nrows):
 value = booksheet.cell(row,col).value
 if row ==0:
 writeData = writeData+'	'+'["'+value+'"]'+'='+'{'
 else:
 writeData=writeData+'"'+str(booksheet.cell(row,col).value)+'", '
 else:
 writeData=writeData+'},
'
 else:
 writeData=writeData+'}

'
else :
 fileOutput.write(writeData)
fileOutput.close()
