Print a string as hexadecimal bytes

I have this string: Hello, World! and I want to print it using Python as '48:65:6c:6c:6f:2c:20:57:6f:72:6c:64:21'. hex() works only for integers. How can it be done?
You can transform your string to an integer generator. Apply hexadecimal formatting for each element and intercalate with a separator: >>> s = "Hello, World!" >>> ":".join("{:02x}".format(ord(c)) for c in s) '48:65:6c:6c:6f:2c:20:57:6f:72:6c:64:21
