Phyton programming language

Python programming language was conceived in the late ____s

1980s

When does Phyton Programming language implemented starts?

December 1989

The Python programming language was conceived in the late 1980s, and its implementation was started in December 1989 by _______ at (Centrum Wiskunde & Informatica (CWI) in the Netherlands) as a successor to the ABC programming language “capable of exception handling and interfacing with the Amoeba operating system.”

Guido van Rossum

Guido van Rossum, the author of Python Programming Language was reading the first published draft script of

“Monty Python's Flying Circus”, a 70s BBC Comedy

He wanted a short concise name for the language and his love for Monty Python was the reason for naming the language Python. What is the reason why he wanted a short concise name for the language?

his love for Monty Python was the reason for naming the language Python.

Python is developed under an _______________ approved open source license, making it freely usable and distributable, even for commercial use.

OSI (Open Source Initiative)

Python's license is administered by

Python Software Foundation

Python is a general purpose programming language that is also used for _________. But python can be used for everything that is done in java.

Scripting

Where does python and java are interpreted? . Most scripts are small programs with less than 100 lines.

Runtime

Most scripts are

small programs with less than 100 lines.

is the name given to entities like class, functions, variables etc. in Python.

Identifiers

It helps differentiating one entity from another.

Identifier

Identifiers can be a combination of

lowercase(a to z) or uppercase (A to Z) or digits (0 to 9) or an underscore (_).

What are the examples of VALID Names

myClass, var_1 and print_to_screen

An identifier can be start with a digit. 1variable is valid,but variable1 is invalid

False, “cannot be start with digit”. 1variable is INVALID, Variable1 is VALID

Keywords can be used as identifiers.

False,Keywords cannot be used as Identifiers

We cannot use special symbols like !, @, #, $, % etc. in our identifier.

True

Identifier can be of any length.

True

is a way of collecting and organizing data in such a way that we can perform operations on these data in an effective way.

DATA STRUCTURE

Data Structures is about rendering data elements in terms of some relationship, for better organization and storage.

True

In simple language, Data Structures are structures programmed to store disordered data, so that various operations can be performed on it easily.

False

Choose the right statement for Data Structure

It represents the knowledge of data to be organized memory. It should be designed and implemented in such a way that it reduces the complexity and increases the efficiency.

Anything that can store data can be called as a data structure. What are the “Basic types of data structures”.

Integer, Float, Boolean, Char all are data structures.

Integer, Float, Boolean, Char, They are known as

Primitive Data Structures.

are used to store large and connected data.

Arrays, Linked list, Binary tree, Stack.

are used to store large and connected data. Some example are Arrays, Linked list, Binary tree, Stack.

Complex Data Structures

There are ____ collection (Arrays) data types in the Python programming language

a collection which is ordered and changeable. Allows duplicate members.

List[]

is a collection which is ordered and unchangeable. Allows duplicate members.

Tuple ()

is a collection which is unordered, unchangeable, and unindexed. No duplicate members.

Set {}

is a collection which is ordered and changeable. No duplicate members.

Dictionary

is a very commonly used linear data structure which consists of group of nodes in a sequence.

linked list

is a hierarchical data structure in which each node has at most two children generally referred as left child and right child.

Binary Tree

is an abstract data type with a bounded capacity. It is a simple data structure that allows adding and removing elements in a particular order.

Stack

is a finite set of instructions or logic, written in order, to accomplish a certain predefined task.

ALGORITHM

“_______” is not the complete code or program, it is just the core logic of a problem, which can be expressed either as an informal high- level description.

“Algorithm”

is a picture (graphical representation) of the problem - solving process. Pseudocode is an artificial and informal language that helps programmers develop algorithms. It is a "text based" detail (algorithmic) design tool

FLOWCHART

is an artificial and i formal language. It is a text - based detail design tool

False

Writing variables in Python programming language is case sensitive.

True

An identifier can be of any length.

True

Is this line of code correct? number_list = {6, 7, 10, 9, 4}

False

There are five collection (arrays) data types in Python programming language.

False

Is this line of code correct? names_list = ["Aimee", "Cathy", "Katrina", "Martha", "Shola"]

True

There are no errors in this code snippet. def addition(first_number, second_number): sum = first_number + second_number print("The sum of two numbers is {0:,}." .format(sum))

True

Is this line of code correct? number_list = [None] * 5

true

The acronym CWI means Centrum Wiskunde & Informatica.

True

There are no errors in this code snippet. number_input = int(input("Enter a number: ")) if number_input == 1: print("The equivalent color value is red.") elif number_input == 2: print("The equivalent color value is orange.") elif number_input == 3 print("The equivalent color value is yellow.") elif: print("There is no equivalent color value.")

False

Is this a valid variable name? us_dollar$

false

Anything that can store data can be called as a data structure, hence integer, float, boolean, and char are data structures.

True

Primitive data structure examples are integer, float, boolean, and stack.

False

Binary tree is a simple data structure that allows adding and removing elements in a particular order.

False

There are no errors in this program. integer_set = [5, 9, 6, 11, 14] sum = 0 for counter in range(5): sum = sum + integer_set(counter) print("The sum of array set is {0}." .format(sum))

false

There are no errors in this code snippet. print("Addition of two numbers") sum = addition(10, 2): print("The sum of two numbers is {0:}." .format(sum))

False

Is this a valid variable name? 1st_number

False

There are no errors in this code snippet. def area_circle(radius): area = 3.1416 * radius * radius print("The area of the circle is {0:,.4f}." .format(area)) Correct!

true

The list() Constructor It is also possible to use the list() constructor when creating a new list.

true

Access Items List items are indexed and you can access them by referring to the index number.

true

Negative indexing means start from the end, -1 refers to the last item, -2 refers to the second last item etc.

true
