Python with Mathematics and Sequences – PART 2 & tricky cool Integer calculations

Here we will see some known and easy way of computing different mathematical and sequential things.

NOTE: This post is in continuation to the PART 1, however its not necessary to refer part I and you could take it as an independent post also.

Calculate the average of a series

# For an arbitrary sequence
def average(seq, total=0.0):
num = 0
for item in seq:
total += item
num += 1
return total / num

# For a sequence type such as a list or a tuple
def average(seq):
return float(sum(seq)) / len(seq)

Python with Mathematics and Sequences – PART 1

Sequence is a particular order in which related things follow each other. Its fun and its very intuitive and so called logical. So lets start.

NOTE: Here we are not going to discuss what are different types of sequences are. We will see how we can achieve different sequences using Python.

Geometric Sequence

In a Geometric Sequence each term is found by multiplying the previous term by a constant.

2, 4, 8, 16, 32, 64, 128, 256, …

This sequence has a factor of 2 between each number. Each term (except the first term) is found by multiplying the previous term by 2.

Guidelines for young python developers – PART 2 | Fun with happy coding

NOTE: This part is independent and doesn’t require PART-1 to be referred compulsorily, but its advisable šŸ™‚

Extended Slicing

Slicing in Python is a mechanism to select a range of items from Sequence types like strings, list, tuple, etc.

Syntax: [stat:end:step]

>>> L = range(10)
>>> L[::2]
[0, 2, 4, 6, 8]
mylist[::-1] # will reverse a list

# Reverse a string
>>> S = 'Abhilash'
>>> S[::-1]
'haslihbA'

Why is it important to secure your network?

Before starting i would like to share one of my personal experience with one of my client.

I got a call in late evening and my client was almost lasted all his hope. According to him, one of his competitor actually managed to access his network and successfully stolen all of his confidential data stored on that server. Not only this he also deleted all the files from the network so that my client should rework on everything. This was bad on his part, but that late evening made him realize that why so much of security awareness is happening these days.
