# The built-in function `open` opens a file and returns a file object.
# Read mode opens a file for reading only.
try:
    f = open("file.txt", "r")
    try:
        # Read the entire contents of a file at once.
        string = f.read()
        # OR iterate over the file line-by-line:
        for line in f:
            # Do something with line.

def format_filename(s):
    """Take a string and return a valid filename constructed from the string.
Uses a whitelist approach: any characters not present in valid_chars are
removed. Also spaces are replaced with underscores.
 
Note: this method may produce invalid filenames such as ``, `.` or `..`
When I use this method I prepend a date string like '2009_01_15_19_46_32_'
and append a file extension like '.txt', so I avoid the potential of using
an invalid filename.
