How do I combine two lists in tuple?
using zip() method to merge the two list elements and then typecasting into tuple. Approach #4 : Using enumerate(), alternative to zip(). This method uses two for loops to enumerate through lists and merge the two lists. Approach #5: Using map() and lambda .
Is it possible to concatenate tuples with list?
This can have application in situations we need to combine values to form a whole. Let’s discuss certain ways in which this can be performed. We can solve this particular problem using the list comprehension technique in which we can iterate for each tuple list and join it with other tuple attribute to join.
How do you merge two tuples in Python?

How do you convert a list of tuples to a list?
If you’re in a hurry, here’s the short answer: use the list comprehension statement [list(x) for x in tuples] to convert each element in your tuples list to a list. This works also for list of tuples with varying number of elements.
Is a tuple a list of lists?
Tuples are identical to lists in all respects, except for the following properties: Tuples are defined by enclosing the elements in parentheses ( () ) instead of square brackets (  ). Tuples are immutable.
Are tuples and lists the same?
The main difference between lists and tuples is the fact that lists are mutable whereas tuples are immutable. A mutable data type means that a python object of this type can be modified. An immutable object can’t.
What are two differences between lists and tuples?
We can conclude that although both lists and tuples are data structures in Python, there are remarkable differences between the two, with the main difference being that lists are mutable while tuples are immutable. A list has a variable size while a tuple has a fixed size.
Are tuples faster than lists?
Tuple is stored in a single block of memory. Creating a tuple is faster than creating a list. Creating a list is slower because two memory blocks need to be accessed. An element in a tuple cannot be removed or replaced.
What are lists and tuples What is the key difference between the two?
One of the most important differences between list and tuple is that list is mutable, whereas a tuple is immutable. This means that lists can be changed, and tuples cannot be changed.
Why use a tuple over a list?
Tuples are more memory efficient than the lists. When it comes to the time efficiency, again tuples have a slight advantage over the lists especially when lookup to a value is considered. If you have data which is not meant to be changed in the first place, you should choose tuple data type over lists.
Why are lists better than arrays?
Arrays can store data very compactly and are more efficient for storing large amounts of data. Arrays are great for numerical operations; lists cannot directly handle math operations. For example, you can divide each element of an array by the same number with just one line of code.
Why is it difficult to store linked list in an array?
Linked lists have following drawbacks: So we cannot do a binary search with linked lists. 2) Extra memory space for a pointer is required with each element of the list. 3) Arrays have better cache locality that can make a pretty big difference in performance.
Can you have an ArrayList of arrays?
You can create an ArrayList of arrays just like with any other objects using ArrayList constructor. This will create an ArrayList of String arrays. Note: While declaring the ArrayList of arrays, we cannot specify the length of the String array objects it is going to have.
Which two Cannot be stored in an ArrayList?
ArrayList. The ArrayList class implements a growable array of objects. ArrayLists cannot hold primitive data types such as int, double, char, and long (they can hold String since String is an object, and wrapper class objects (Double, Integer).
Can you create an ArrayList of ArrayLists?
Since ArrayList supports generics, you can create an ArrayList of any type. It can be of simple types like Integer , String , Double or complex types like an ArrayList of ArrayLists, or an ArrayList of HashMaps or an ArrayList of any user defined objects.
Can ArrayList hold different types?
