Making Python display .txt files from directories -

- 

print "which category view? savory, dessert, cake, soup or drink?    " category = raw_input() if category == "savory": #opens directory according answer.     os.listdir("savory")  elif category == "drink":     os.listdir("drink")  elif category == "cake":     os.listdir("cake")  elif category == "dessert":     os.listdir("dessert")  elif category == "savory":     os.listdir("savory")  elif category == "drink":     os.listdir("drink")  elif category == "cake":     os.listdir("cake")  elif category == "dessert":     os.listdir("dessert")

i trying create code display recipes have been saved under directories. when run code nothing displayed if input recipes directories.

firstly, you're not printing anything. e.g 

os.listdir("savory")

should 

print(os.listdir("savory"))

secondly, can dramatically shorten code:

print("which category view? savory, dessert, cake, soup or drink?") print(os.listdir(raw_input().lower()))

if want restrict user accessing other directories:

safe = ['savory', 'dessert', 'cake', 'soup', 'drink']  category = raw_input().lower() if category in safe:     print(os.listdir(category)) else:     print('you have typed invalid category')
