/prog/ - My first useful python program!

Name: Anonymous 2013-01-21 23:01

Good evening my good friends of /prog/! Thanks to your encouragement, I made my first useful python program today. Basically it generates an HTML script that displays every image in a directory. I'll post it in hopes that you can use it !~{^-^}~♥



#index generator for directory of images for HTML

import os

import fnmatch



FNL = os.listdir(".")



f = open('index.html','w')

f.write("<html><head><title>Index of...</title></head><body>")



#make a list of workable files in this

for FileName in FNL:

    if fnmatch.fnmatch(FileName, '*.jpg'):

        f.write("<img src=\""+FileName+"\"></img><br>")

    if fnmatch.fnmatch(FileName, '*.jpeg'):    

        f.write("<img src=\""+FileName+"\"></img><br>")

    if fnmatch.fnmatch(FileName, '*.gif'):    

        f.write("<img src=\""+FileName+"\"></img><br>")

    if fnmatch.fnmatch(FileName, '*.png'):    

        f.write("<img src=\""+FileName+"\"></img><br>")

    if fnmatch.fnmatch(FileName, '*.bmp'):    

        f.write("<img src=\""+FileName+"\"></img><br>")

        

#close up by writing the ending tags

f.write("</body></html>")

Well, that's one way to do it.

You don't need the closing </img> tag. All browsers treat img as a closed tag. You can write <img .../> if it makes you feel better.

There's a lot of duplicate code there. That entire for loop can be written:

PATTERNS = ['*.jpg', '*.jpeg', '*.gif', '*.png', '*.bmp']

for FileName in FNL:

    for FilePattern in PATTERNS:

        if fnmatch.fnmatch(FileName, FilePattern):

            f.write("<img src=\""+FileName+"\"></img><br>")

Then if you need to change the write statement, you only need to do it once, and adding new formats is as simple as:

PATTERNS = ['*.jpg', '*.jpeg', '*.gif', '*.png', '*.bmp', '*.tiff']
