* The code:
age = input("How old are you? ")
height = input("How tall are you? ")
weight = input("How much do you weigh? ")
print(f"So, you're {age} old, {height} tall and {weight} heavy.")
* When will input run? At the variable initalization or when calling the function?
* How do I debug, and step through the code to see what's happening in the background (and possibly see the anwser for the prev question)?

* Questions
** Why does Opening and Reading the file is done in 2 steps? What's the difference?
in_file = open(from_file)
indata = in_file.read()
"Opening" a file doesn't actually bring any of the data from the file into your program. It just prepares the file for reading (or writing), so when your program is ready to read the contents of the file it can do so right away.
*** Source:
https://stackoverflow.com/questions/20308998/what-is-the-difference-between-opening-and-reading-a-file-in-python
** What does 'w' mean? (from ex16)
target = open(filename, 'w')
It's a string with a character in it for the kind of mode for the file.
'w' = write
'r' = read
'a' = append
* Note
" character messes up the copy in org or emacs

* Questions:
** How does the program reads the file?
readline
** How does it loops over the lines?
readline will return an empty string when no more data is available
*** https://stackoverflow.com/questions/28936140/use-readline-to-read-txt-file-python3
** Why doesnt he uses a for loop? (instead of return) -later
Good to know:
"The second method still reads the file line by line and does not load the whole file into memory, right? nishant Nov 14 '19 at 7:24"
"@nishant correct Ilan Kleiman Dec 15 '19 at 1:42"
** What is "with" in python? -later
** Why should I use builting python utils instead of *nix utils? -later
* Notes:
strip: for text formatting
* Log:
Takes a long time to watch the video.

* Drills
** Take a look at how you used range . Look up the range function to understand it.
tldr, a "function" that generates a sequence of numbers:
class range(start, stop[, step]):
start
The value of the start parameter (or 0 if the parameter was not supplied)
stop
The value of the stop parameter
step
The value of the step parameter (or 1 if the parameter was not supplied)
-------
I found it among python 3.8.3 built-in functions.
but!
Turns out it's not a function after all!
It's an immutable sequence type.
"a range object will always take the same (small) amount of memory" ... "as it only stores the start, stop and step values" and generates numbers on the fly
note: similar in shell is: seq
source: https://docs.python.org/3/library/stdtypes.html#range
** Could you have avoided that for-loop entirely on line 22 and just assigned range(0,6) directly to elements?
Do you mean line 21 book? (typo)
Yes! Because range will generate a list that can be appended added as is.
** Find the Python documentation on lists and read about them. What other operations can you do to lists besides append?
extend, insert, remove, pop, clear, index, count, sort, reverse, copy
fascinating! programming is cool! you can do so much with it

*Drills
** The gold_room has a weird way of getting you to type a number. What are all the bugs in this way of doing it? Can you make it better than what Ive written? Look at how int() works for clues.
Non greedy is less than 50 but only 1 and 0 qualify.
Nicer ways:
-> check for numbers
-> also check for None and All strings
-> sanitize input for int(), (int can take 2 variables)
