File opening modes (r, w, a ...)


Hello

I share a very valuable table I found on
StackOverflow about file opening modes

If like me you always forget the details of
file opening mode, the following table provides
a good summary

                   | r   r+   w   w+   a   a+
------------------|--------------------------
read              | +   +        +        +
write             |     +    +   +    +   +
write after seek  |     +    +   +
create            |          +   +    +   +
truncate          |          +   +
position at start | +   +    +   +
position at end   |                   +   +
