Day 2 of Learning Python: Practising Python Fundamentals 🐍

1. Variables in Python

A variable is a name that refers to a value.

`name = "Python"
age = 25

print(name)
print(age)

Output:

Python
25`

Python automatically determines the type of a value when it is assigned to a variable.

2. Operators in Python

Operators are symbols or keywords that perform operations on values.

*Arithmetic operators
*
`a = 10
b = 3

print(a + b) # Addition
print(a - b) # Subtraction
print(a * b) # Multiplication
print(a / b) # Division
print(a % b) # Modulus

Output:

13
7
30
3.3333333333333335
1`

Comparison operators

Comparison operators compare two values and return True or False.

`print(10 > 5)
print(10 == 5)
print(10 != 5)

Output:

True
False
True`

3. Type Conversion

Type conversion means converting a value from one data type to another.

`age = "25"

age = int(age)

print(age)
print(type(age))

Output:

25


Here, int() converts the string "25" into the integer 25.

1. Taking Input from the User

Python provides the input() function to accept information from a user.

name = input("Enter your name: ")

print("Hello", name)

The program asks for a name and displays a greeting.
