Now offered considering the fact that Python three.four, import and instantiate a Path object Using the file identify, and Test the is_file system (note this returns Real for symlinks pointing to standard files as well):
The amazing detail about rely() is that it won't crack your code or require you to toss an exception when x just isn't found.
The stream is positioned in the beginning in the file. ``a'' Open for creating. The file is made if it doesn't exist. The stream is positioned at the conclusion of the file. Subsequent writes to the file will usually end up on the then recent conclusion of file, irrespective of any intervening fseek(three) or comparable. ``a+'' Open for reading through and creating.
