Python 2.6, File read() problems in Windows Xp

Hi all: I am trying to read a non-text file as a string by using Python read(), however, it seems there is some thing wrong with it. I can use read() on text file correctly, but unable to read .xls file correctly. (The program can read any file correctly in Fedora 10) Any idea how to solve this p

How to locate the bit in bits string?

Hi: If I use an integer to represent bits: e.g. 99 represents '1100011' How can I locate, say the second bit of 99(i.e. '1')? Although bin(99)[4] could be used to locate it, this transform cost too much memory (99 only needs 2Bytes, while string '1100011' needs 7Bytes). Anyone knows how to loca

Efficient bits manipulation in Python

Hi: I have a bit-code :'1011011', how can I reverse it to '1101101'? Another question is I know how to transform the string '110' into integer 6, does anyone know how to transform integer 6 to a string '110'? Thank you very much:) -- Li -- Time is all we have and you may find one day you
