python使用xlrd实现检索excel中某列含有指定字符串记录的方法

2015-05-09 16:21 1306 查看

这里利用xlrd，将excel中某列数据中，含有指定字符串的记录取出，并生成用这个字符串命名的txt文件

import os
import xlrd,sys
# input the excel file
Filename=raw_input('input the file name&path:')
if not os.path.isfile(Filename):
raise NameError,"%s is not a valid filename"%Filename
#open the excel file
bk=xlrd.open_workbook(Filename)
#get the sheets number
shxrange=range(bk.nsheets)
print shxrange
#get the sheets name
for x in shxrange:
p=bk.sheets()[x].name.encode('utf-8')
print "Sheets Number(%s): %s" %(x,p.decode('utf-8'))
# input your sheets name
sname=int(raw_input('choose the sheet number:'))
try:
sh=bk.sheets()[sname]
except:
print "no this sheet"
#return None
nrows=sh.nrows
ncols=sh.ncols
# return the lines and col number
print "line:%d col:%d" %(nrows,ncols)
#input the check column
columnnum=int(raw_input('which column you want to check pls input the num(the first colnumn num is 0):'))
while columnnum+1>ncols:
columnnum=int(raw_input('your num is out of range,pls input again:'))
# input the searching string and column
testin=raw_input('input the string:')
#find the cols and save to a txt
outputfilename=testin + '.txt'
outputfile=open(outputfilename,'w')
#find the rows which you want to select and write to a txt file
for i in range(nrows):
cell_value=sh.cell_value(i, columnnum)
if testin in str(cell_value):
outputs=sh.row_values(i)
for tim in outputs:
outputfile.write('%s  ' %(tim))
outputfile.write('%s' %(os.linesep))
outputfile.close()

希望本文所述对大家的Python程序设计有所帮助。
