# array[start:stop:step]

# start = include everything STARTING AT this idx (inclusive)
# stop = include everything BEFORE this idx (exclusive)
# step = (can be ommitted) difference between each idx in the sequence

arr = ['a', 'b', 'c', 'd', 'e']

arr[2:] => ['c', 'd', 'e']

arr[:4] => ['a', 'b', 'c', 'd']

arr[2:4] => ['c', 'd']

arr[0:5:2] => ['a', 'c', 'e']

arr[:] => makes copy of arr

Slice position: 0   1   2   3   4   5   6
Index position:   0   1   2   3   4   5

>>> p = ['P','y','t','h','o','n']
# Why the two sets of numbers:
# indexing gives items, not lists
>>> p[0]
 'P'
>>> p[5]
 'n'

# Slicing gives lists
>>> p[0:1]
 ['P']
>>> p[0:2]
 ['P','y']

slicing in python

Comment

In Python, we perform slicing using the following syntax: [start: end].
fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"]
sliced_fruits = fruits[1:3]
print(sliced_fruits) # ["Orange", "Lemon"]
Slicing in Python is very flexible. If we want to select the first n elements 
of a list or the last n elements in a list, we could use the following code:
fruits[:n]
fruits[-n:]
fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"]
print(fruits[:3])
# ["Banana", "Orange", "Lemon"]
print(fruits[-2:])
# ["Apple", "Mango"]

The basic rules of slice are:
I'''
 The slice generates index/integers from - start, start + step, start +
step + step, and so on. All the numbers generated must be less than
the stop value when step is positive.'''
II'''  
 If step value is missing then by default is taken to be 1 '''
III'''
 If start value is missing and step is positive then start value is by default
taken as 0.'''
IV'''
 If stop value is missing and step is positive then start value is by
default taken to mean till you reach the ending index(including the
ending index)'''
V'''
 A negative step value means the numbers are generated in
backwards order i.e. from - start, then start - step, then start -step
-step and so on. All the numbers generated in negative step must
be greater than the stop value.'''
VI'''
 If start value is missing and step is negative then start value takes default
value -1'''
VII'''
 If stop value is missing and step is negative then stop value is by
default taken to be till you reach the first element(including the 0
index element)'''
