What does 'w', 'r', and 'a' mean in Python Files Topic ?

Meaning of 'w', 'r', and 'a' in Python Programming Language Files Topic ?

▪ It's really just a string with a character in it for the kind of mode for the file.

▪ If you use 'w', then you are saying "open this file in 'write mode" - hence
the 'w' character.

▪ There's also 'r' for "read," 'a' for append, and modifiers on these.
