Just say

dir = 'path_to_my_folder'
if not os.path.exists(dir): # if the directory does not exist
    os.makedirs(dir) # make the directory
else: # the directory exists
    #removes all files in a folder
    for the_file in os.listdir(dir):
        file_path = os.path.join(dir, the_file)
        try:
            if os.path.isfile(file_path):
                os.unlink(file_path) # unlink (delete) the file
        except Exception, e:
            print e
