simple: 'aöaö'.encode() is b'a\xc3\xb6a\xc3\xb6'. If you save this to disk and then read in text mode, when you do seek(2) it will move by two bytes, so that seek(2); read(1) will result in an error UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in p...
Difference between staticmethod and classmethod

a.foo(1)
# executing foo(<__main__.A object at 0xb7dbef0c>,1)
With classmethods, the class of the object instance is implicitly passed as the first argument instead of self.

# executing class_foo(<class '__main__.A'>,1)
You can also call clas...
How to reliably guess the encoding between MacRoman, CP1252, Latin1, UTF-8, and ASCII

Statistical approach
Count character (NOT byte!) frequencies...
