How does python know to add a space between a string literal and a variable? -


so learning python hard way. in 1 of exercises print string literals variables between them. noticed unlike other languages python automatically adds space between string literal , variables. curious how that. below example of mean.

example.py:

total_so_questions_asked = 1 print "i have asked", total_so_questions_asked, "question far."

terminal:

$ python example.py have asked 1 question far.

this silly , not important curious, , hoping can enlighten me!

it's cool feature of python.

there 2 things having multiple arguments does: adds space around parameters necassary, , converts each of arguments string seperately.

let's @ how simple can make potentially complicated code using these features:

a = 5 b = 3 c = + b print a, "plus", b, "equals", a+b

if couldn't have list of individually casted parameters, it'd ugly:

print str(a) + " plus " + str(b) + " equals " + str(a+b)

from zen of python, lines 1 , 3:

beautiful better ugly.

simple better complex.

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
