Day 8

I jumped way ahead and tried Selenium today. It was great. I was quickly able to identity things that will help with work.

I am still going though the questions and excesizes on the automate the boring stuff website.

Day 7

I was originally thinking that this would be
automate the boring stuff using python in 30 days... but then I thought, lets make it 15 days... but here we are on day 7 and honestly I think I am 20% though it.

Im doing this in my spare time, a minimum of 30 minutes a day, but sometimes, understanding things takes longer, or I go back and rewatch videos.

Today,  was my first successful coding, I was able to take a problem and create a solution ( a simple solution) but it was a great feeling to be able to do that.

Starting today, Im going to go though the questions on the website and follow along with the website a bit more than I have been doing.

I will likely copy and paste more info from the website as I move forward as well as information from Python.org and Stackoverflow

https://automatetheboringstuff.com/chapter0/


Doing these questions is HARD

there is also some homework with each one of them... this is really getting me going good.

but it takes time... I think I need to take it easy on the 30 day thing or it is going to stress me out.

Just focus on doing 30 minutes a day and I will be fine.

Day 6

https://docs.python.org/2/library/

Functions use arguments

Print(variable) for example
In this example

1. def spam():
2.     eggs = 99
3.     return eggs
4. 
   
5. number = spam()
6. print (number)

Line 6 needs the argument (number)  or it will never print 99, you will get an error.

Global and local scope. 

pythontutor.com/visualize.html

Change a global variable with a local scope variable 

1. def spam():
2.        global eggs
3.        eggs = 'Hello'
4.        print = (eggs)
5. 
   
6. 
   
7. eggs = 42
8. spam()
9. print(eggs)

Try and Except

Left off on lecture 12

Day 5

global and local scope

I went back to lecture 8
I need to understand functions better. I want to make sure that I understand how they have a return and specifically understand this reddit thread that I created.

https://www.reddit.com/r/learnpython/comments/3z340l/i_am_very_new_can_someone_explain_why_this_doesnt/

Day 4

these two programs give me different outputs, why? 

total = 0
for num in range (101):
   total = total + num
   print (total)


total = 0
for num in range (101):
   total = total + num
print (total)

for loop

this is not like a while loop



Range (start, end, step)


Standard library.
Math
Random, etc

import Statement

import module

import random

import sys

use pip to import third party modules

Day three Section 2

# this is a comment


Functions are like mini programs ... input() for example is a function, functions have arugments that is the () this is a function because python doesnt do the memory management... that is all handled by the language, python is written in C so  C is what does the memory management and python just knows input()

I can write my own functions.

int(), str(),float() convert values' data type


Flow control statements.




Boolean values - True, False need to be capitalized.


comparison vales
Operator Meaning
== Equal to NOT = which is assignment dont get these confused
!= Not equal to
< Less than
> Greater than
<= Less than or equal to
>= Great than or equal to


Int == str
False

Truthy Falsey
bool()




Boolean operators

and
or
not


Flow control statements
If, Else and Elif statements

Day two

Section:1 Python Basics

Quiz 1: just a check in

https://automatetheboringstuff.com/chapter1/

Lecture 2: Basic Terminology

Operator	Operation	Example	Evaluates to...
**	Exponent	2 ** 3	8
%	Modulus/remainder	22 % 8	6
//	Integer division/floored quotient	22 // 8	2
/	Division	22 / 8	2.75
*	Multiplication	3 * 5	15
-	Subtraction	5 - 2	3
+	Addition	2 + 2	4

Lecture 3 Writing our first program.




Lecture 3 really slowed me down.




This line

• print('You will be ' + str(int(myAge) + 1) + ' in a year.')

My age is a string, then it is turned into an interger... then one is added, then it is turned back into a string to concatenate to be 'you will be (myage +1) in a year.
Looking forward to day three.
