javascript - focusing on google maps api according to latitude and longitude -


i got code of drawing polylines in google maps here want focus on map according latitude , longitude, added line -> map.setcenter(new google.maps.latlng(-122.5868225097656,45.56117947133065)); polyline didn't appear because latitude , longitude outside screen , line added (map.setcenter) didn't change here code:

-122.5868225097656,45.56117947133065 -122.6348876953125,45.493833740092185

are invalid latlong(s). reason why app not working right.

i tried interchange values. , working fine.

map.setcenter(new google.maps.latlng(45.56117947133065,-122.5868225097656));   var flightplancoordinates = [     new google.maps.latlng(45.56117947133065,-122.5868225097656),     new google.maps.latlng(45.493833740092185,-122.6348876953125)   ];

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
