Daphne
- My ultimate goal is to automate redundant stuffs in life to save 1 hour a day in the next 3 months. I manage to go through the foundation, and successfully re-implement some instruction to organize files in my Mac, and crawl a simple data set
- Scrape data from Yahoo Finance, the FS release date
- Scrape data from 10 most popular job listing sites
- Scrapre data from Linkedin profiles

Milestone projects
- Auto parsing and renaming files
- Automate files in the local computer
- Web Scrapping with Beautiful Soup
- Automate Web Browsing with Selenium
- Automate Tinder swiping
Knowledge checkpoints
-
Milestone 0: Set up the environment (You can skip this and come back later if the syllabus you are taking provies the coding editor)
- Install Python 3
- Install the IDE (eg. Pycharm, Visual Studio Code, etc)
- Execute and run code with terminal commands (eg. cd, ls, python3, etc)
-
Milestone 1: Learning Basic Python syntax
- get to know different data types (eg.
str(),int(),list()) - variables and naming convention
- comment #
print()- one variables
- multiple variables using
format()
- read the input data from users using
input()- restrict the data type using
str(),int(),list()…
- restrict the data type using
- get to know different data types (eg.
-
Milestone 2: Working with numeric data - integer and float
- Arithmetic Operators (output: result)
- Comparison (output: True/ False)
- Shortcut. Eg.
num += 1 - Commonly used methods: absolute
abs(),round(), etc - Work with numbers in string format. Eg. "3"
- Advanced math
import math
-
Milestone 3: Working with textual data - string
- Single quotes vs. Double quotes
- Create multi-line string using triple quotes
'''or\n - Commonly used functions and methods in string
- Check data types:
type() - Check string length:
len() - Index
lower()orupper()- Concatination
replace()
- Check data types:
-
Milestone 4: Working with boolean
-
Milestone 5: Conditional statement
- If Else
- If Elif Else
-
Milestone 6: Loops and iteration
- While loop
- For loop
-
Milestone 7: Function
- Write your own function
- 3rd party function
- Global and Local scopes
-
Milestone 8: Working with data in a container - list, tuple, set, dictionary
- List
- access a list using loop
append()- list comprehension
- Dictionary
- understand key - value pair
- access value from a key: dict['key']
- add new key to a dict
- update many keys in one shot:
update() - delete a key and its value:
pop()ordel - check what keys are there:
dict.keys() - check what values are there:
dict.values() - check what key-value pairs are there:
dict.items()
- Tuple and Set
- List
-
Milestone 8: Modules, Libraries
- Modules
- create modules
- variables in module
- name the module, create an alias for the module
- import module
- commonly used modules: OS, csv, etc
- Libraries
- import libraries, create an alias for the module
- commonly used libraries for automation: beautiful soup, selenium, etc
- Modules
