Explanation / Answer

import os
# getting the current working directory
cwd = os.getcwd()
# getting the names of all the files in the working directory
files = os.listdir(cwd)
# iterating through all the files
for filename in files:
    # skipping this python file
    if filename == "directory.py":
        continue
    try:
        print "Working on " + filename
        # r+ mode for reading and writing
        f = open(filename, "r+")
        # reading all the data of the file
        data = f.read()
        # replacing blank space by underscore
        data = data.replace(" ", "_")
        # f.read changed the file pointer to the end of the file
        # f.seek(0) brings it to the beginning of the file
        f.seek(0)
        # writing the new data
        f.write(data)
        # closing the file pointer
        f.close()
    # except for if it's not a file, maybe a directory
    except:
        continue
