How to have Python look and see if there is a file it needs and if there isn't create one?
Basically I want Python to look for my file name KEEP-IMPORTANT.txt, but when I create my app using py2app it doesn't work because it doesn't have the file. When I try and make the file it won't work (I think because python has to generate it).
I want Python to check if the file exists so that if it does then it doesn't generate the file, otherwise it does.
This one-liner will check to see if the file exists, and create it if it doesn't.
open("KEEP-IMPORTANT.txt", "a")
This is the best way:
try:
with open(filename) as file:
# do whatever
except IOError:
# generate the file
There's also os.path.exists(), but this can be a security concern.
import os.path
from os import path
if path.exists('highScore.txt'):
print("It exists")
else:
print("It doesn't exist")
Another clean and small solution if you want to check and create the file only with out writing anything right away would be this.
import os
if os.path.exists(file_path) == False:
open(file_path, "w").close
