Read and search text file in Python? -

i need write python script reads flat text file, searches string, , rewrites new text file.

i have (example) script:

import re read = open("file.txt", "r") data = file.read() print data newfile = open("newfile.txt", "w") line in read:   if re.match("(.*)dst="+str_var"(.*)", line):     print newfile, line, file.close() 

is there easier or more correct way? (i know pretty nothing python. code derived i've found in tutorials, google, etc.)

thanks!

this may trick

read_file = open("file.txt", "r") data = read_file.read() read_file.close() file_content = re.sub("\d+", "", data) word = your_word if word in file_content:    newfile = open("newfile.txt", "w")    print >> newfile, word    newfile.close()
