Selection

Now suppose we have `10 to buy a pen. On visiting the stationery shop, there are a variety of pens priced at `10 each. Here, we have to decide which pen to buy. Similarly, when we use the direction services of a digital map, to reach from one place to
another, we notice that sometimes it shows more than one path like
the least crowded path, shortest distance path, etc. We decide
the path as per our priority. A decision involves selecting from
one of the two or more possible options. In programming, this
concept of decision making or selection is implemented with the
help of if..else statement.

In the following example, if the age entered by the
user is greater than 18, then print that the user is
eligible to vote. If the condition is true, then the indented
statement(s) are executed. The indentation implies that
its ex*****on is dependent on the condition. There is no
limit on the number of statements that can appear as a
block under the if statement.

age = int(input("Enter your age "))
if age >= 18:
print("Eligible to vote")

Indentation in python

In most programming languages, the statements within
a block are put inside curly brackets. However, Python
uses indentation for block as well as for nested block
structures. Leading whitespace (spaces and tabs) at
the beginning of a statement is called indentation.
In Python, the same level of indentation associates
statements into a single block of code. The interpreter
checks indentation levels very strictly and throws up
syntax errors if indentation is not correct. It is a common
practice to use a single tab for each level of indentation.
In the program 6-4, the if-else statement has two
blocks of statements and the statements in each block
are indented with the same amount of spaces or tabs.

Cloud computing relies on sharing of resources to achieve coherence and economies of scale.

Advocates of public and hybrid clouds note that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing the burst computing capability: high computing power at certain periods of peak demand.

Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server.
