Python is one object-oriented programming language that is widely used. It can create software, websites, games, and mobile applications. “How to create List of Lists in Python” is a fairly common problem every programmer will encounter. So, what are our options? Everything will be explained to you.

What is List of Lists in Python?

Lists are used to hold several items in a single variable in any programming language. In Python, you may make a list by separating each element with a comma and enclosing all the components in square brackets. Integer, float, text, and other types of data can be stored there.
Python has the option of building a list inside another list. Simply described, it is a nested list containing one or more lists as elements inside.
To understand things more clearly, let’s look at the following example:

list_of_lists = [['a', 25, 69, 'Apple'],
[5, 'doll', 854, 41.2],
[8, 6, 'car', True]]

print(list_of_lists)

Output:

[['a', 25, 69, 'Apple'], [5, 'doll', 854, 41.2], [8, 6, 'car', True]]

Here, [[‘a’, 25, 69, ‘Apple’], [5, ‘doll’, 854, 41.2] and [8, 6, ‘car’, True]] are individual lists that are supplied as elements to create a new list. This is an example of ”a list of lists in Python”.

Methods to create List of Lists in Python

Method 1: Use the list comprehension

In Python, users can make a list of rankings through using the feature list comprehension. This is extremely simple to use. Now let learn more about this using the following example:

lst1 = [1, 2, 3,4] 
mylst = [lst1 for i in range(3)] 
print(mylst)

Output:

[[1, 2, 3, 4], [1, 2, 3, 4], [1, 2, 3, 4]]

We could now guarantee users that the issue is simple to fix.

Method 2: Use the list initializer

In Python, we can prepare a Set of Lists while using the list initializer. This is extremely simple to use. Let us learn more about this solution by using the following example:

lst1 = [19,11,9] 
lst2 = [97,54,45] 
lst3 = [lst1, lst2] 
print(lst3)

Output:

[[19, 11, 9], [97, 54, 45]]

Method 3: Use the append()

In Python, individuals can create a list of checklists via using append(). This is extremely simple to use. Let us learn more about it using the following example:

lst1 = [11,12,13] 
lst2 = [14,15,16] 
lst = [] 
lst.append(lst1) 
lst.append(lst2) 
print(lst)

Output:

[[11, 12, 13], [14, 15, 16]]

Method 4: Use for-loop

Excepting some methods mentioned above, using for-loop is also a great solution for you to creat List of Lists in Python. Look at the example below to understand more about this solution:

list = []

# Create List of list
for i in range(2):
list.append([])
for j in range(3):
list[i].append(j)

print(lst)

Output:

[[a,b,c],[a,b,c]]

Conclusion

Python lends itself well to high-level systems. Nonetheless, performance would be marginally inferior to that of the native language. You quickly gain safety, range of motion, and maintenance, however. Individual solutions provided in these tools are some of the most fundamental for anyone faced with the problem “How to create List of Lists in Python“. If you still need assistance or have basic Python questions, a growing community of people are usually willing to assist you. In addition, we anticipate a more creative day filled with new ideas and code.
