PYTHON 101; GETTING STARTED

** WHAT IS PYTHON**

First released in 1991 and created by Guido van Rossum, python is an interpreted, high-level and general-purpose programming language.

GETTING STARTED

Python Installation

You can download the various versions of python through your preferred browser(preferred versions 3.6+).

Clicking on download will download python.
Click on the..exe file to set up python in your computer

Writing the First Code
Open the Command Prompt and type python

You will be able to access Python.

print(Hello World)

FUNDAMENTALS OF PYTHON

Here we get to know Python;

• Variables

• Strings and Comments

• Operators

• Lists

• Dictionaries

• Sets

• Functions

Variables

A variable is a storage location (Identified by the memory adress) paired with an associated symbolic name(an identifier), which contains some known or unknown quantity of information refered to as a value.

name= eric
age= 19
name and age are variables

Strings and Comments

# is used to convert a string to a comment

print("hello world")
#print ("Hello world")

Operators

There are different types of operators

• Boolean
  Boolean values are two which are True or False

• Comprison
  Comparison operators are

1. Equal (==)
2. Not equal (!=)
3. Greater than (>)
4. Less than (<)
5. Greater or equal to (>=)
6. Less than or equal to (<=)
7. Logical and or not

Lists

In lists, characters are enclosed in brackets [].

Dictionaries

Items are stored in a key, value pair in a dictionary.
Dictionaries are defined using curly braces {} and are ordered.

Sets

Sets are defined using curly braces {} and are unordered.

ages = {19,20,21,22,23}
ages
{19,20,21,22,23}

Functions

A function is a block of code that runs when it is called.
a function is defined with the def keyword.

def name():
    print('eric')

name()
eric

Here, name() is calls the function to execute.
