ruby - Convert orientation (N, S, SE, SSE etc) to bearing angle -


is there functionality in ruby or gem convert string orientation (examples in title) bearing in degrees, bearing defined follows?

a numerical value representing direction in degrees, true north @ 0° , progressing clockwise.

this works 8 main cardinal directions:

def cardinal_direction_degrees(s)   h = {n: 0, ne: 45, e: 90, se: 135, s: 180, sw: 225, w: 270, nw: 315}   h[s.to_s.downcase.to_sym] end  puts cardinal_direction_degrees('n') #=> 0 puts cardinal_direction_degrees('sw') #=> 225

you can add remaining directions adding more elements hash.

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
