Basic Coding Python: How to Install Python?
Python can be easily installed on your computer system with the help of the command terminal. Open the command line window and simply type ‘Python’. If Python is already installed on your system then the output will be in the form of a version number. But if not, then a link to download Python will appear on your screen.
You can download Python for Windows as well as Mac for free. Follow the steps given below to download Python.
- First, visit the official website of Python and download the Python installer. You need to choose a version of your choice. It is recommended to choose the latest version.
- Now, run the installer and it will start the installation process.
- You can choose a custom path to add Python to your system Path.
- Now, after installation, verify the installation using the command ‘python3 —version’ or if you type ‘Python’ it will also show the version number.
Nowadays, there are many online Python compilers that allow coding online without downloading Python from your system remotely. PW Lab is an online coding platform that can help you practise Python online easily.

Basic Coding Python: Starting with Python
Check out some of the starting basics of Python, which are given below.
1. Comments
Comments in Python are used to explain any segment of your Python code. Comments are not executed during the compilation of code. We use ‘#’ hashtags to represent comments in Python.
| Basic Coding Python |
| # Python program to add two numbers in python
num1 = 4 num2 = 5 sum = num1 + num2 |
2. Keywords
Python has various reserved words which can perform specific functions. Some of the keywords frequently used in Python are given below. Some of the basic keywords used in Python are class, finally, is, return, None, continue, from, while, except, raise, not, for, def, etc.
3. Built In-data types
Python consists of built in data types which can be used to perform various tasks. There are various built-in data types in Python: numerical, strings, booleans, lists, tuples, etc.
3. Operators in Python
Python consists of many operators which can help to perform various tasks. Some of the operators used in python are mentioned below.
| Basic Coding Python: Operators | |
| Arithmetic Operator in Python | |
| Operator | Description |
| +(Addition) | It is used to add two or more values. |
| -(Subtraction) | It is used to subtract two or more values. |
| *(Multiplication) | It is used to multiply two values on either side of the operator. |
| /(Division) | It is used to divide the left hand operator by right hand operator |
| %(Modulus) | It returns the remainder when the left-hand operator is divided with the right-hand operator. |
| Assignment Operator in Java | |
| = | It assigns the value to a left-side operand from a right-side operand. |
| += | It keeps on adding the right operator to the left operand and assigning the result obtained to the left operand. |
| -= | It subtracts the right-hand operand from the left-hand operator and assigns the value to the left operator. |
| *= | It is used to multiply the value in the right hand to the left hand operand. |
| /= | It takes the division of the two operands and then assigns the result to the left operand. |
| %= | It takes the modules and assigns the remainder value at the left-hand operand. |
| ^= | It is used to perform exponential calculation and assign the calculated value to the left hand operand. |
| Identity operator in Python | |
| is | It returns true if two variables or objects refer to the same memory location. |
| is not | It returns true if two variables or objects do not refer to the same memory location. |
| Relational Operators in Python | |
| == | It checks whether the left-hand and right-hand operands are equal. |
| != | It checks whether the left-hand and right-hand operands are not equal. |
| > | If the value of the left operand is greater than the right hand operand, then it returns true. |
| < | If the value on the left-hand side is smaller than the right-hand side, then it returns true. |
| >= | It tells the left side value is greater or equal to the right-hand side. |
| <= | It means the left value is smaller or equal to the right-hand side. |
| Logical Operators in Python | |
| and | It will return true only if both the operands are true. |
| or | It will return true if any of the operands on either side are true. |
| not | It returns true when both the operands are false. It is also used to negate the value of a variable. |
| Bitwise Operator in Python | |
| & | Bitwise AND |
| | | Bitwise OR |
| ^ | Bitwise XOR |
| ~ | Bitwise NOT |
| << | Left Shift |
| >> | Right Shift |
Basic Coding Python: Functions
In Python, functions are declared using the “def” keyword. Functions are the blocks of code that run a command when it is called inside the code. Functions are reusable and can be used multiple times whenever required in Python.
You can easily pass data into a function, which can process it using the code given inside the function to return a processed result. Let us understand functions with a simple factorial example in Python.
| Basic Coding Python |
| def factorial(n):
if n == 0: return 1 else: return n * factorial(n – 1) # Take input from the user num = int(input(“Enter a number to calculate the factorial: “)) # Check if the number is negative if num < 0: print(“Factorial cannot be calculated for negative numbers.”) else: result = factorial(num) print(“Factorial of”, num, “=”, result) |
Output
| Enter a number to calculate the factorial:
5 Factorial of 5 = 120 |
Basic Coding Python: Variables
Variables are used to store different values inside. Suppose x = 5 then here x stores the value 5. Python automatically picks up the data type of the value stored inside the variable; hence, there is no need to declare the data types of the variable. You can simply create variables in Python by giving them a name.
Basic Coding Python: Indentation
Python follows indentation, which is the space given at the beginning of the Python code. In other programming languages, indentation is not of much importance. But in Python, indentation is very important. Check an example below. We put the print statement with a space after the conditional if statement.
| if 10>20:
print(“The given condition is true.”) |
You must use proper indentation in your Python code. Otherwise, it will give error during execution.
