Python installation and environment setup on windows

-
Now, all we know, what is a programming language, and why we need it. Now, how we can get started with coding? Can we use a plain text editor or wanna install any Softwares? We have to install Python to get started coding with Python and obviously every programming language has its own package installation. So, let's see how to install Python and the environment. Here we use the word environment, it is nothing than the environment in which we write, compile (convert to machine code), and run (getting output to the user). If you've already installed Python and your favorite code editor, you can skip this lesson.

Installing Python

Installation of python varies by the OS (Operating system), let's see how to install Python on windows.


  1. Visit python windows download page in python.org
  2. If your windows is 32 bit (x86), download from  https://www.python.org/ftp/python/3.7.7/python-3.7.7.exe , else skip this step. 
  3. If windows is 64 bit, then download from https://www.python.org/ftp/python/3.7.7/python-3.7.7-amd64.exe
  4. Open the installer file, and follow the screenshots below. 

      If you get stuck feel free to reach me out through the comment box. 

      
Check (tick) 'Add python to PATH', and 'click Install Now'

Make sure pip is selected. pip is a python package manager
used to install external libraries (code written by others).
Click next

Click Install

Now, it will start the installation, wait for a while

Congratulations, the installation is successful. 



    Let's make sure the installation is successful by running python.

    Open command prompt on Windows or Terminal on Mac / Linux, then type python on the terminal. If you are a Linux user, the python command will execute the python2 instead of python3. But, we've to execute our python3. So, you've to type python3 in order to run python3.

The command python3 will open a python shell on the command prompt or terminal. As you can see below.


Now, we can type our python code here. just type print('Hello world') and hit enter. It will give an output of "Hello world"

Python variables

-
 Variables in Python In Python, variables are used to store values and are declared by assigning a value to a name. The value can be of any data type, such as a number, string, list, or object. Here's an example of how to declare a variable in Python: x = 5 # declares a variable x and assigns it the value of 5 name = "John" # declares a variable name and assigns it the value of "John" fruits = [ "apple" , "banana" , "orange" ] # declares a variable fruits and assigns it the value of a list You can also assign a value to a variable after it has been declared: x = 5 x = 10 # x now has the value of 10 Variable names in Python can contain letters, numbers, and underscores, but cannot start with a number. Python is case-sensitive, so x and X are considered to be different variables. It's a good practice to give variables descriptive and meaningful names, so that it will be easy to understand the code later. Also, it's a...

Functions in Python

-
Functions in Python In Python, functions are blocks of code that are designed to perform a specific task. Functions are defined using the def keyword, and can accept parameters and return values. The general syntax of a function definition is as follows: def function_name ( parameter1, parameter2, ... ):     # code to execute     return value Here's an example of a simple function that takes two parameters and returns their sum: def add ( a, b ):     return a + b Functions can be called by using their name followed by parentheses, and passing any required arguments. result = add( 3 , 4 ) # result is 7 Functions can also be used without returning any value, in such cases, the return statement is not needed. def print_hello ():     print ( "Hello, World!" ) print_hello() # it will print "Hello, World!" Functions can also accept a variable number of arguments by using *args or **kwargs . *args is used to pass a variable number ...

Control structures in Python

-
Control Structures  In Python, control structures are used to control the flow of a program, by executing certain code blocks based on certain conditions. Here are some of the most commonly used control structures in Python:  If-else statements : If-else statements are used to perform different actions based on whether a certain condition is true or false. The syntax of an if-else statement is as follows: if condition:     # code to execute if condition is true else :     # code to execute if condition is false For loops : For loops are used to iterate over a sequence of items, such as a list, tuple, or string. The syntax of a for loop is as follows: for item in sequence: # code to execute for each item in the sequence While loops : While loops are used to repeat a block of code as long as a certain condition is true. The syntax of a while loop is as follows: while condition:      # code to execute while condition is true Break and co...
