great course, highly recommended !

Example 2: python list comprehension

#example: removing common elements found in `a` from `b`.
a = [1,2,3,4,5]
b = [5,6,7,8,9]
# desired output: [1,2,3,4]

# gets each item found in `a` AND not in `b`
print([i for i in a if i not in b])

Example 3: python data structures

#string
string = 'Hi my name is Dr.Hippo'
#integer(whole number)
integer = 12345
#floating point number
fl = 123.456
#list
li = [1,2,3,,'string',None]
#boolean
t = True
f = False
#none(equivalent to null or undefined in other languages)
n = None
#dictionary
dictionary = {'key':'value'}

Example 4: python data structures

list = [same as array with different features] 
array = [23, 'arrayItem', True, ['Hi', 34, False] ]
dictionary = {'key' : 'value'}
object = class testObj:
tuple = ( "a", "b", "c", "d" ); #same as list but non-changable
