# Python program to demonstrate # Removal of elements in a List # Creating a List List = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] print("Initial List: ") print(List) # Removing elements from List # using Remove() method List.remove(5) List.remove(6) print("\nList after Removal of two elements: ") print(List)

Chiqish
Dastlabki ro'yxat:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]


Ikki element olib tashlanganidan keyin ro'yxat:
[1, 2, 3, 4, 7, 8, 9, 10, 11, 12]
2-misol:
Python 3

# Creating a List List = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] # Removing elements from List # using iterator method for i in range(1, 5): List.remove(i) print("\nList after Removing a range of elements: ") print(List)

Chiqish
Bir qator elementlarni olib tashlaganingizdan so'ng ro'yxat:
[5, 6, 7, 8, 9, 10, 11, 12]
Ro'yxatdagi elementlarni o'chirish uchun murakkabliklar (remove() usuli):
Vaqt murakkabligi: O(n)
Kosmik murakkablik: O(1)
2-usul: pop() usulidan foydalanish
pop() funktsiyasidan elementni ro'yxatdan olib tashlash va qaytarish uchun ham foydalanish mumkin, lekin sukut bo'yicha u ro'yxatning faqat oxirgi elementini olib tashlaydi, elementni Ro'yxatning ma'lum bir pozitsiyasidan olib tashlash uchun element indeksi uzatiladi. pop() usuliga argument sifatida.
Python 3

List = [1, 2, 3, 4, 5] # Removing element from the # Set using the pop() method List.pop() print("\nList after popping an element: ") print(List) # Removing element at a # specific location from the # Set using the pop() method List.pop(2) print("\nList after popping a specific element: ") print(List)

Chiqish
Elementni ochgandan so'ng ro'yxat:
[1, 2, 3, 4]


Muayyan elementni ochgandan so'ng ro'yxat:
[1, 2, 4]
Ro'yxatdagi elementlarni o'chirish uchun murakkabliklar (pop() usuli):
Vaqt murakkabligi: O(1)/O(n) (O(1) oxirgi elementni olib tashlash uchun, O(n) birinchi va oʻrta elementlarni olib tashlash uchun)
Kosmik murakkablik: O(1)
Ro'yxatni kesish
Biz tilim yordamida pastki qatorlar va pastki ro'yxatlarni olishimiz mumkin. Python List-da butun ro'yxatni barcha elementlar bilan chop etishning bir necha yo'li mavjud, ammo ro'yxatdagi elementlarning ma'lum diapazonini chop etish uchun biz Slice operatsiyasidan foydalanamiz .
