| Half and Half: | 10.5% to 18% |
|---|---|
| Whole milk: | 3.25% |
| Reduced fat milk: | 2% |
| Semi-skim milk: | 1.8% |
| Low fat milk: | 1% |
| Skim milk: | 0.0 to 0.5% |
What is half and half? It is a simple blend of equal parts of whole milk and light cream. So milk and cream.

So “str” in Python 2 is now called “bytes,” and “unicode” in Python 2 is now called “str”.
Oh boy, that’s why I have been so confused working on both Py2 and Py3 on various projects.
It’s year 2020. From this point on, it’s all Py3. So I/O is all byte string, and try to keep unicode/str inside python. IO_byte_string.decode() -> unicode_string, unicode_string.encode() -> IO_byte_string. So:
with open(filename, 'rb') as f:
byte_string = f.read() # binary
# external knowledge: data encoded in utf-8
my_string = byte_string.decode('utf-8')
# my_string is a list of "code points"
# Output say, using 8859-1 (Latin-1)
output_byte_string = my_string.encode('8859-1')
OR
# external knowledge: data encoded in utf-8 with open(filename, 'r', encoding='utf-8') as f: my_string = f.read() # code points # Output say, using 8859-1 (Latin-1) with open(filename2, 'r', encoding='8859-1') as f: f.write(my_string)

I started out with “+”, then was told not to use it. So I listened and used “join”. Then later I used format. Now it seems that I should use “f”.
f'{s} {t}' # 78.2 ns
s + ' ' + t # 104 ns
' '.join((s, t)) # 135 ns
'%s %s' % (s, t) # 188 ns
'{} {}'.format(s, t) # 283 ns
Template('$s $t').substitute(s=s, t=t) # 898 ns

Good read: https://tjcx.me/posts/i-wasted-40k-on-a-fantastic-startup-idea/
Make something people want. It’s Y-Combinator’s motto and a maxim of aspiring internet entrepreneurs. The idea is that if you build something truly awesome, you’ll figure out a way to make some money off of it.
So I built something people wanted. Consumers wanted it, doctors wanted it, I wanted it. Where did I go wrong?
“To succeed, an offering must create value for all entities involved in the exchange—target customers, the company, and its collaborators.”
It’s interesting how you can randomize some well-known retro games so you don’t always keep doing the same thing on the same old game. This brings new life to old school games. =) More amazingly I wonder how the code authors find out the parts in the rom to randomize. True geeks.
