azure sql database - Is there a way to rewrite EXCEPT statements into NOT IN statements in SQL? -


i'm few weeks learning sql, , finished problem on homework assignment using in , not in. managed correct answer, however, used except clause, aren't allowed use yet. can tell, except , not in similar statements in sql, can't understand difference is. here's general format of query:

select * table x in (     select x     /* ... subquery*/     except     select x     /* ... other subquery*/  )

is there way rewrite general query without using except statement? how except , not in differ each other in general?

edit: this other post seems have information, seems focus on exists , not in, have different purposes don't they?

this might understand difference between except , not in

except operator returns distinct rows left hand side table not exist in right hand side table.

on other hand, "not in" return rows left hand side table not present in right hand side table not remove duplicate rows result.

utf 8 - split utf-8 string into bytes in python -

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
