本文實例講述了Python實現(xiàn)刪除文件中含指定內(nèi)容的行。分享給大家供大家參考，具體如下：

#!/bin/env python

import shutil,sys,os

darray = [

"Entering directory","In function ","Leaving directory","__NR_SYSCALL_BASE","arm-hisiv100-linux-ar ","arm-hisiv100-linux-gcc ","but argument is of type","dereferencing type-punned pointer will break strict-aliasing rules","differ in signedness","does break strict-aliasing rules","embedded '\\0' in format","excess elements in array initializer","implicit declaration of","make -C "," rm -f","this is the location of the previous definition","warning: multi-line comment"

]

def isInArray (array,line):

for item in array:

if item in line:

return True

return False

if __name__ == '__main__':

argv = sys.argv

argc = len(argv)

if argc < 2:

print "Usage: %s " %(os.path.basename(argv[0]))

exit()

fname = argv[1]

fresult = fname + ".result"

with open(fname,'r') as f:

with open(fresult,'w') as g:

for line in f.readlines():

if not isInArray(darray,line):

g.write(line)

希望本文所述對大家Python程序設(shè)計有所幫助。
