i've tried reinstalling datetime libary using sudo apt-get install --reinstall --purge libpython3.4-stdlib libpython2.7-stdlib

any idea on how fix problem? i'm running: 3.13.0-48-generic #80-ubuntu smp thu mar 12 11:16:15 utc 2015 x86_64 x86_64 x86_64 gnu/linux

as wrote here

because apt-file search /usr/bin/datetime.so returns no output:

make backup of file /usr/bin/datetime.so:

sudo mv /usr/bin/datetime.so /usr/bin/datetime.so.bak

and run again

sudo add-apt-repository -y ppa:chris-lea/node.js

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
