Find And Replace String From Multiple Files In A Folder Using Python
I want to find string e.g. "Version1" from my files of a folder which contains multiple ".c" and ".h" files in it and replace it with "Version2.2.1" using python file.
Anyone know how this can be done?
Here's a solution using os, glob and ntpath. The results are saved in a directory called "output". You need to put this in the directory where you have the .c and .h files and run it.
Create a separate directory called output and put the edited files there:
import glob import ntpath import os output_dir = "output" if not os.path.exists(output_dir): os.makedirs(output_dir) for f in glob.glob("*.[ch]"): with open(f, 'r') as inputfile: with open('%s/%s' % (output_dir, ntpath.basename(f)), 'w') as outputfile: for line in inputfile: outputfile.write(line.replace('Version1', 'Version2.2.1'))
Replace strings in place:
IMPORTANT! Please make sure to back up your files before running this:
import glob for f in glob.glob("*.[ch]"): with open(f, "r") as inputfile: newText = inputfile.read().replace('Version1', 'Version2.2.1') with open(f, "w") as outputfile: outputfile.write(newText)
