Right, because that’s the ASCII value for Ctrl-Z.

In this line, “readchar.readkey()” returns a string of length 1.  It contains one character, with a value of 1A in hex.  When you pass that through “repr”, you end up with a string of length 7: “u”, apostrophe, backslash, “x”, “1”, “a”, and apostrophe.  Naturally, when you compare that to a string of length 1, it doesn’t match.

It’s a string containing one character.  Wasn’t that obvious from your output?
