Python Useful Tuple Vs List Differences

Here're the quick differences between Tuple and List. This list is useful for your projects and interviews. 

Tuple Vs. Lists in Python 

List

1. Comma-separated elements inside a square bracket [] make a list.
2. The elements are indexed. It starts from '0'
3. These you need to enclose in a single quote and separate by a comma.
4. A list can contain another list, which is called a NESTED list.
5. Use type() function to get the type of data it is.
6. The list is mutable (you can change the data). The objects (elements) can be of different data types.
7. Here're examples on the List.

Tuple

1. The elements comma-separated and enclosed in parenthesis () 
2. The elements are indexed. It starts from '0'
3. A tuple can have heterogeneous data (integer, float, string, list, etc.)
4. A tuple is immutable. So, you can't change the elements.
5. Use type() function to get the type of data it is. 
6. Here're examples of Tuple.

List Example

#Illustration of creating a list 

new_list=[1, 2, 3, 4] 

print(new_list) 

# Homogeneous data elements 

new_list1=[1, "John", 55.5] 

print(new_list1) 

# Heterogeneous data elements 

new_list2=[111, [1, "Clara", 75.5]] 

# Nested list 

print(new_list2)

Output

[1, 2, 3, 4]
[1, ‘John’, 55.5]
[111, [1, ‘Clara’, 75.5]]

Tuple Example

#Illustration of unpacking a tuple 

 new_tuple2=(111, [1, "Clara", 75.5], (2, "Simon", 80.5)) 

# Nested tuple 

print(new_tuple2) x, y, z=new_tuple2 

print(x) 

print(y) 

print(z) 

Output

111
[1, ‘Clara’, 75.5]
(2, ‘Simon’, 80.5)
