Python list insert() method is “used to insert an element to the list at the specified index.”
Syntax
list.insert(index, element)Parameters
The insert() function takes two parameters:
- index – It is a required parameter and a position where an element needs to be inserted.
- element – It is a required parameter, which is the element to be inserted in the list.
Return value
The insert() method doesn’t return anything; returns None. It only updates the current list.
Example 1: How to Use list.insert() Method
GoT = ['Daenerys', 'Jon', 'Tyrion']
GoT.insert(1, 'Varys')
print(GoT)
Output
Example 2: Inserting a Tuple (as an Element) into the List
To insert a tuple in List in Python, use the list.insert() method. We can also add a Tuple as an element to the specified position.
GoT1_list = ['Daenerys', 'Jon', 'Tyrion']
Friends1_tuple = ('Rachel', 'Monica', 'Phoebe')
GoT1_list.insert(2, Friends1_tuple)
print(GoT1_list)Output
Example 3: AttributeError: ‘str’ object has no attribute ‘insert’
If we try to insert anything in a string because the string doesn’t have attribute insert().
# AttributeError
string = "192111"
string.insert(10, 1)
print(string)Output
AttributeError: 'str' object has no attribute 'insert'Example 4: Insert in a List Before any Element
listA = [11, 21, 19, 46, 18]
# Element to be inserted
element = 20
# Element to be inserted before 3
beforeElement = 46
# Find index
index = listA.index(beforeElement)
# Insert element at beforeElement
listA.insert(index, element)
print(listA)Output
[11, 21, 19, 20, 46, 18]Example 5: Adding an Element to the Beginning of a List
data = ['bmw', 'audi', 'mercedez']
data.insert(0, 'jaguar')
print(data)
Output
['jaguar', 'bmw', 'audi', 'mercedez']That’s it!
