Range concept

 

Python method example

In Python, a method is a function that belongs to an object and is called using the dot (.) operator.

1. String Method Example

name = "nilesh gupta"

print(name.upper())
print(name.lower())
print(name.title())

Output:

NILESH GUPTA
nilesh gupta
Nilesh Gupta

2. List Method Example

students = ["Amit", "Rahul", "Priya"]

students.append("Neha")
print(students)

students.remove("Rahul")
print(students)

Output:

['Amit', 'Rahul', 'Priya', 'Neha']
['Amit', 'Priya', 'Neha']

3. User-Defined Method Example

class Student:
    def display(self):
        print("Welcome to Python")

s = Student()
s.display()

Output:

Welcome to Python

Here, display() is a method of the Student class, and s.display() calls that method.

Python range function example

Python range() Function

The range() function is used to generate a sequence of numbers, commonly with a for loop.

1. Basic Example

for i in range(5):
    print(i)

Output:

0
1
2
3
4

2. range(start, stop)

for i in range(1, 6):
    print(i)

Output:

1
2
3
4
5

The stop value (6) is not included.

3. range(start, stop, step)

for i in range(2, 11, 2):
    print(i)

Output:

2
4
6
8
10

4. Reverse Range

for i in range(5, 0, -1):
    print(i)

Output:

5
4
3
2
1

Syntax

range(start, stop, step)

• start → starting number

• stop → ending limit, not included

• step → difference between numbers
