Python List Methods in Hindi In Python Programming

Python Programming In Hindi me aaj hum Python list methods ke baare me baat karenge. Python ek powerful programming language hai jismein list methods ka use karke hum apni lists ko asaani se modify kar sakte hain. Lists ek ordered collection of items hoti hain jo kisi bhi type ke data ko store kar sakti hain. Aaiye, kuch important list methods ke baare me detail me jaanate hain jo aapko Python Programming In Hindi sikhne me madadgar sabit honge.

Python List Methods In Hindi

1. Python append()

append() method ka use list me new element add karne ke liye hota hai. Yeh method element ko list ke last me insert karta hai.

Example:

l = ['Banana', 'Papaya']
print('Before add:', l)
l.append('Grapes')
l.append('Mango')
print('After add:', l)

Output:

Before add: ['Banana', 'Papaya']
After add: ['Banana', 'Papaya', 'Grapes', 'Mango']

2. Python clear()

clear() method list ko puri tarah se clear kar deta hai, yani list se saare elements ko remove kar deta hai.

Example:

l = ['Banana', 'Papaya']
print('Before clear:', l)
l.clear()
print('After clear:', l)

Output:

Before clear: ['Banana', 'Papaya']
After clear: []

3. Python copy()

copy() method list ki ek copy return karta hai. Yeh shallow copy hoti hai, yani nayi list ka data purani list ke data se linked nahi hota.

Example:

l1 = ['Banana', 'Papaya']
l2 = l1.copy()
l1.append('Mango')
l1.append('Grapes')
print('list l1:', l1)
print('list l2:', l2)

Output:

list l1: ['Banana', 'Papaya', 'Mango', 'Grapes']
list l2: ['Banana', 'Papaya']

4. Python insert()

insert() method bhi list me new element add karta hai, lekin yeh specified index par element ko insert karta hai. Agar us index par pehle se koi element hai, toh usse shift kar deta hai.

Example:

l = ['Papaya', 'Mango']
print('Before insert:', l)
l.insert(0, 'Grapes')
l.insert(2, 'Apple')
print('After insert:', l)

Output:

Before insert: ['Papaya', 'Mango']
After insert: ['Grapes', 'Papaya', 'Apple', 'Mango']

5. Python pop()

pop() method list se item remove karta hai. By default yeh last item remove karta hai, lekin agar index number pass karein toh us particular index se item remove karta hai.

Example:

l = ['Papaya', 'Mango', 'Grapes']
print('Before remove:', l)
l.pop()
l.pop(0)
print('After remove:', l)

Output:

Before remove: ['Papaya', 'Mango', 'Grapes']
After remove: ['Mango']

6. Python remove()

remove() method first occurrence of specified value ko remove karta hai. Agar specified value list me nahi hai toh ValueError raise karta hai.

Example:

l = ['Papaya', 'Mango', 'Grapes', 'Mango']
print('Before remove:', l)
l.remove('Mango')
print('After remove:', l)

Output:

Before remove: ['Papaya', 'Mango', 'Grapes', 'Mango']
After remove: ['Papaya', 'Grapes', 'Mango']

7. Python reverse()

reverse() method list ke elements ko reverse order me kar deta hai.

Example:

l = ['Papaya', 'Apple', 'Mango']
print('Before reverse:', l)
l.reverse()
print('After reverse:', l)

Output:

Before reverse: ['Papaya', 'Apple', 'Mango']
After reverse: ['Mango', 'Apple', 'Papaya']

8. Python sort()

sort() method list ko sort karta hai. Sorting karte waqt list me same type ke items hone chahiye.

Example:

l = ['Papaya', 'Apple', 'Mango']
print('Before sort:', l)
l.sort()
print('After sort:', l)

Output:

Before sort: ['Papaya', 'Apple', 'Mango']
After sort: ['Apple', 'Mango', 'Papaya']

9. Python count()

count() method list me specified element ki occurrences ko count karta hai.

Example:

l = ['Papaya', 'Mango', 'Grapes', 'Mango']
print('Count of Mango:', l.count('Mango'))

Output:

Count of Mango: 2

10. Python extend()

extend() method ek list ke elements ko dusri list me add karta hai.

Example:

l1 = ['Papaya', 'Mango']
l2 = ['Grapes', 'Apple']
print('Before extend:', l1)
l1.extend(l2)
print('After extend:', l1)

Output:

Before extend: ['Papaya', 'Mango']
After extend: ['Papaya', 'Mango', 'Grapes', 'Apple']

11. Python index()

index() method specified element ka first occurrence index return karta hai.

Example:

l = ['Papaya', 'Mango', 'Grapes', 'Apple']
print('Index of Mango:', l.index('Mango'))

Output:

Index of Mango: 1
