How to Add Floats to a List in Python (original) (raw)

Last Updated : 27 Nov, 2024

Adding floats to a list in Python is simple and can be done in several ways. The easiest way to add a float to a list is by using the append() method. This method adds a single value to the end of the list.

Python `

a = [1.2, 3.4, 5.6]

#Add a float value (7.8) to the end of the list a.append(7.8) print(a)

`

Output

[1.2, 3.4, 5.6, 7.8]

_Let's look into Other various methods that are used to Add Floats to a List in Python.

Using extend()

If we want to add multiple float numbers at once, we can use the extend() method. This method adds all the elements from one list to another.

Python `

a = [1.2, 3.4, 5.6] b = [7.8, 9.0]

Add all elements from list b to the end of list a

#using extend() a.extend(b) print(a)

`

Output

[1.2, 3.4, 5.6, 7.8, 9.0]

Using insert()

If we want to add a float at a specific position in the list, we can use the insert() method. This method allows us to add a value at any index.

Python `

a = [1.2, 3.4, 5.6]

Insert the float value 2.3 at index 1 in the list

#using insert() a.insert(1, 2.3) print(a)

`

Output

[1.2, 2.3, 3.4, 5.6]

Using list concatenation

Another way to add floats to a list is by using the + operator to concatenate two lists. This method creates a new list by combining two lists together.

Python `

a = [1.2, 3.4, 5.6] b = [7.8, 9.0]

Concatenate list a and b

#using the + operator and assign it back to a a = a + b print(a)

`

Output

[1.2, 3.4, 5.6, 7.8, 9.0]
