How to modify specific element of a list?

የ አንድን list specific element ብቻ ለይተን modify ማድረግ እንችላለን።

Syntax :
list_name[i] = new element

ለምሳሌ : my_list በሚለው list ውስጥ index 2 ላይ ያለውን element('cap') ወደ 'book' እንቀይር።

my_list = ['bag', 'pen', 'cap', 'pen']

my_list[2] = 'book'
print(my_list)

#Output : ['bag', 'pen', 'book', 'pen']

Old list : ['bag', 'pen', 'cap', 'pen']
Modified list : ['bag', 'pen', 'book', 'pen']

3. index() method

The index() method returns the position at the first occurrence of the specified item (value).

In Python, a method is a function that is associated with a class. It is defined inside the class and can be called using an instance of the class. Methods can perform operations on the data stored in the class and can also modify the state of the object.

ለምሳሌ : የ ከዚህ list የ4ን index ለማወቅ ከፈለግን

new_list = [1, 5, 6, 4, 7]

index_of_4 = new_list.index(4)

#Output : 3
