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

#!/bin/env pythonimport shutil, sys, osdarray = [  "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 Falseif __name__ == '__main__':  argv = sys.argv  argc = len(argv)  if argc < 2:    print "Usage: %s <file>" %(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)

另外還可參考：bash刪除文件中含"指定內容"的行
