Removing Items from a List in Python

Python provides many ways to remove items from a list. Let's understand remove(), pop(), del, and clear() with examples.

Python में list से item हटाने के कई तरीके हैं। आइए remove(), pop(), del और clear() को उदाहरण के साथ समझें।

1. Using remove() - by value

Copystudents = ["Raj", "Simran", "Aman"]
students.remove("Simran")
print(students)

Output:

["Raj", "Aman"]

2. Using pop() - remove last item

Copystudents = ["Raj", "Simran", "Aman"]
students.pop()
print(students)

Output:

["Raj", "Simran"]

3. Using pop(index)

Copystudents = ["Raj", "Simran", "Aman"]
students.pop(0)
print(students)

Output:

["Simran", "Aman"]

4. Using del - by index

Copystudents = ["Raj", "Simran", "Aman"]
del students[1]
print(students)

Output:

["Raj", "Aman"]

5. Using del - full list

Copystudents = ["Raj", "Simran", "Aman"]
del students
# Now students no longer exists

Output:

NameError: name 'students' is not defined

6. Using clear()

Copystudents = ["Raj", "Simran"]
students.clear()
print(students)

Output:

[]

7. Removing Dynamically (user input)

Copystudents = ["Raj", "Simran", "Aman"]
to_remove = input("Enter name to remove: ")
if to_remove in students:
    students.remove(to_remove)
else:
    print("Name not in list")
print(students)

Output:

Enter name to remove: Simran
['Raj', 'Aman']
