Python Bootcamp

This repository is used to store stuff related to me learning Python from the course The Modern Python 3 Bootcamp at Udemy.com.

Dictionaries

Like objects in JavaScript. Key-value pairs. Unordered (no index) and there can't be duplicates in the keys.

Example:

  { 'name': 'hanna'}

Tuples

A list of items that are unique and immutable. Can be used as keys in a dictionary.

Example:

  # Tuple
  (23.14323, 25.2435)

  # Tuple used as key in a Dictionary
  {
    (23.14323, 25.2435): 'Coordinates to home'
  }

Sets

Sort of like objects in JavaScript, but without pairing, just elements, with no index and no duplicates.

Example:

  { 1, 2, 3, 4 }

Command	What it does
|	Joins two sets together, with no duplicates.
&	Intersection of two sets, returns items that exists in both.

Functions

Use def to define a function.

Example:

# Defining function
def my_function ():
  # do stuff

# Using function
myFunction()

*args

Using *args collects the remaining arguments in a function into a tuple.

Example:

def sum_all_nums (*args):
  total = 0
  for num in args:
    total += num
  return total

sum_all_nums(12, 14, 6)
# returns 32

**kwargs

Gathers remaining arguments as a dictionary.

Example:

def fav_colors (**kwargs):
  return kwargs

fav_colors(first="purple", second="white", third="red")

# returns
# { "first": "purple", "second"="white", "third"="red" }
