Problems with python and pyQT

[silusilusilu]

Hi,
i'm new with python: so excuse me for my questions....
i have this code:

def updateLog(self, text):
self.ui.logTextEdit.moveCursor(QTextCursor.End)
self.ui.logTextEdit.insertHtml("<font color=\"Black\">"+text)
self.ui.logTextEdit.moveCursor(QTextCursor.End)

logTextEdit is a QTextEdit object.With this code,i can display only ascii characters: how can i diplay text as hex and binary values?
Thanks

You would need to convert them to strings first. You may want bin()
and hex() for that. And if you want to convert 'q' to 0x71,
hex(ord("q")). And if you want to turn 'hello' into 0x68656c6c6f, you
would need to iterate over 'hello' and run the above function over
every letter.

Also, you are able to display Unicode characters, too.

hex() is a function, not a command. And it only takes the one
parameter, the int to be converted.

For more generality, try the str.format() method. The x type converts
to hex without any prefix, and then you can add the width and fill field.

http://docs.python.org/2/library/stdtypes.html#str.format
http://docs.python.org/2/library/string.html#formatstrings
http://docs.python.org/2/library/string.html#format-specification-mini-language

For starters, try:

print "0x{0:0>2x}".format(12)
or
print "0x{0:0>2X}".format(12)
if you like uppercase hex characters
