How do I convert between tuples and lists in Python?

First, we will see how to convert Tuple into a List in Python.

Convert Tuple with Integer Elements into a List

To convert Tuple to a List, use the list() method and set the Tuple to be converted as a parameter.

Example

Let’s see the example

# Creating a Tuple
mytuple = (20, 40, 60, 80, 100)

# Displaying the Tuple
print("Tuple = ",mytuple)

# Length of the Tuple
print("Tuple Length= ",len(mytuple))

# Tuple to list
mylist = list(mytuple)

# print list
print("List = ",mylist)
print("Type = ",type(mylist))

Output

Tuple =  (20, 40, 60, 80, 100)
Tuple Length=  5
List =  [20, 40, 60, 80, 100]
Type =  <class 'list'>

Convert Tuple with String Elements into a List

To convert Tuple to a List, use the list() method and set the Tuple with string elements to be converted as a parameter.

Example

Let’s see the example

# Creating a Tuple
mytuple = ("Jacob", "Harry", "Mark", "Anthony")

# Displaying the Tuple
print("Tuple = ",mytuple)

# Length of the Tuple
print("Tuple Length= ",len(mytuple))

# Tuple to list
mylist = list(mytuple)

# print list
print("List = ",mylist)
print("Type = ",type(mylist))

Output

Tuple =  ('Jacob', 'Harry', 'Mark', 'Anthony')
Tuple Length=  4
List =  ['Jacob', 'Harry', 'Mark', 'Anthony']
Type =  <class 'list'>

Convert List to Tuple

To convert List to Tuple, use the tuple() −

Example

# Creating a List
mylist = ["Jacob", "Harry", "Mark", "Anthony"]

# Displaying the List
print("List = ",mylist)

# Convert List to Tuple
res = tuple(mylist)
print("Tuple = ",res)

Output

List =  ['Jacob', 'Harry', 'Mark', 'Anthony']
Tuple =  ('Jacob', 'Harry', 'Mark', 'Anthony')
