Several times here on SO I"ve seen people using rt and wt modes for reading and writing files.
For example:
with open("input.txt", "rt") as input_file:
with open("output.txt", "wt") as output_file:
...
I don"t see the modes documented, but since open() doesn"t throw an error - looks like it"s pretty much legal to use.
What is it for and is there any difference between using wt vs w and rt vs r?
