Python tutorial Basics for Beginners – A Step-by-Step Guide

If you’re just starting your programming journey, Python is one of the best languages to learn because of its simplicity and versatility. In our earlier Python tutorial, we covered how to install Python and set up VS Code for coding.

Now, it’s time to move a step further and explore the fundamental building blocks of Python programming, including statements, keywords, variables, and data types. These are essential concepts every beginner must master before diving into advanced Python topics.

In this tutorial, we will cover the following points. I hope you enjoy learning with us!!!!

➡️ Python statements
➡️ Python keywords
➡️ Identifiers in Python
➡️ Variables
➡️ Data types
➡️ Operators
➡️ Comments

lets Start……..

A) Python Statements

A statement in Python is simply an instruction that the Python interpreter can execute.

there are three types of statements available in Python that is:

1)Simple Statement
2)Multi-line Statement
3)Multiple Statements in One Line

we will check the one-by-one as below

1)Simple Statement

A single line of code is a simple statement:
Eg. print(“Hello, World!”)

2) Multi-line Statement

If the code is too long, you can break it into multiple lines using a backslash ( \ ) or parentheses:
E.g. total = 10 + 20 + 30 + \
40 + 50

3) Multiple Statements in One Line

You can also write multiple statements on one line using a semicolon:
E.g. a = 5; b = 10; print(a + b)

Here’s a quick and clear table to understand the different types of statements in Python:

Type	Description	Example
1. Simple Statement	A single line of code that performs one task.	print("Hello World")
2. Multi-line Statement	When a statement is too long, it can be split into multiple lines using a backslash (\) or inside brackets (), [], {}.	python\nx = 10 + 20 + 30 + \n 40 + 50\nprint(x)
3. Multiple Statements in One Line	Two or more statements written on the same line, separated by a semicolon (;).	a = 5; b = 10; print(a + b)

B) Python Keywords

Keywords in Python are reserved words with predefined meanings. They are part of the Python syntax and cannot be used as variable names.
Currently, Python has 35 keywords. Some commonly used ones include:

the explanation are give below which keywords used where to use:

False → Represents something untrue.

True → Represents truth.

None → Represents no value.

and, or, not → Logical operators.

if, elif, else → Conditional statements.

for, while → Loops.

break, continue, pass → Loop control.

def, return, lambda → Functions.

try, except, finally, raise → Error handling.

class → Define a class.

import, from, as → Import modules.

for more…

C) Identifiers in Python

Identifiers means the names given to variables, functions, or classes

Rules for identifiers are given below ✅ :

1) variables, functions, or classes Must begin with a letter or an underscore (_).
2) Cannot start with a number.
3) Special symbols like @, #, $ are not allowed.
4) Case-sensitive (Name and name are different).

_________________________________________________

D) Python Variables

A variable is a name given to a storage location in memory, which holds data that can be used and changed during program execution

OR

A variable in Python is used to store data.

A variable in Python is used to store data. Unlike other programming languages, you don’t need to declare a type. Python assigns it automatically:

Example:
x = 10 # integer (detect the interger data type autometically)
name = “John” # string
pi = 3.14 # float

_________________________________________________

E) Python Data Types

Python provides several built-in data types are as below:

Numeric: int, float, complex

Sequence: list, tuple, range

Text: str

Mapping: dict

Set Types: set, frozenset

Boolean: True, False

None Type: None

Example:
a = 10 # int
b = 3.14 # float
c = “Python” # string
d = [1, 2, 3] # list

_________________________________________________

F) Python Operators

Operators are symbols used to perform operations on variables and values.

there are four types of operator in python are as below:
Arithmetic Operators
Relational (Comparison) Operators
Logical Operators
Assignment Operators

1)Arithmetic Operators

perform basic mathematical operations on numbers

from below example you will understand clearly:

a, b = 10, 3
print(a + b) # Addition → 13
print(a – b) # Subtraction → 7
print(a * b) # Multiplication → 30
print(a / b) # Division → 3.33
print(a % b) # Modulus → 1
print(a ** b) # Exponentiation → 1000
print(a // b) # Floor Division → 3

2) Relational (Comparison) Operators

used to compare two values and return a Boolean result (True or False).

from below example you will understand clearly:

print(a > b) # True
print(a < b) # False
print(a == b) # False

3 ) Logical Operators

used to combine conditional statements and return a Boolean value (True or False).

x, y = True, False
print(x and y) # False
print(x or y) # True
print(not x) # False

To understand clearly above logical operator i have some table of AND,OR & NOT so by using this you will be clearly understand

AND Table

Returns True only if both conditions are True.

A	B	A and B
True	True	True
True	False	False
False	True	False
False	False	False

OR Table

Returns True if at least one condition is True

A	B	A or B
True	True	True
True	False	True
False	True	True
False	False	False

NOT Table

Reverses the Boolean value

A	not A
True	False
False	True

4) Assignment Operators

Assignment operators are used to assign values to variables or update the value of a variable

from below example you will understand clearly:

a = 5
a += 3 # a = a + 3 → 8
a *= 2 # a = a * 2 → 16

Here’s a short and clear table of Python operators with their symbols:

Operator Type	Purpose	Symbols
Arithmetic	Basic math operations	+, -, *, /, //, %, **
Relational	Compare two values	==, !=, >, <, >=, <=
Logical	Combine conditions	and, or, not
Assignment	Assign / update values	=, +=, -=, *=, /=, //=, %=, **=

G) Python Comments

Comments make code readable and easy to understand.

A comment in Python is a note written in the code to explain what the code does.
It is ignored by the Python interpreter and is only meant for developers to understand or share information about the code

1)Single-line comment :

Starts with a # symbol.

Anything written after # on that line will be treated as a comment.

Example:

#This is a single-line comment

print(“Hello”)

2) Multi-line comment :

Written using triple quotes """ or '''.

Useful for longer explanations or documentation

Example:

“””
This program demonstrates
how to use multi-line comments in Python.
“””
print(“Welcome to Python”)
