Can tuple have more than two values?

It is helpful to know some built-in functions with tuples and you will see some important ones in this section. Finally, you'll see that it is also possible to assign multiple values at once to tuples.

How do you make multiple tuples in Python?

But, if the element is itself a mutable data type like a list, its nested items can be changed. We can also assign a tuple to different values (reassignment). We can use + operator to combine two tuples. This is called concatenation.

Can you return 2 values in Python?

Python functions can return multiple values. These values can be stored in variables directly. A function is not restricted to return a variable, it can return zero, one, two or more values.

How do you get multiple values from a list in Python?

Arrays are data structures which hold multiple values. Python does not have arrays but it has lists.
...
Adding Elements in Python Lists

1. append() We can append values to the end of the list. ...
2. insert() You can insert values in a list with the insert() method. ...
3. extend()

Why use a tuple instead of a list?

Tuples are faster than lists.

Some tuples can be used as dictionary keys (specifically, tuples that contain immutable values like strings, numbers, and other tuples). Lists can never be used as dictionary keys, because lists are not immutable.

Why tuple is faster than list?

Tuples are immutable so, It doesn't require extra space to store new objects. Lists are allocated in two blocks: the fixed one with all the Python object information and a variable sized block for the data. It is the reason creating a tuple is faster than List.

Is string immutable in Python?

In python, the string data types are immutable. Which means a string value cannot be updated. We can verify this by trying to update a part of the string which will led us to an error. We can further verify this by checking the memory location address of the position of the letters of the string.

What is difference between tuple and list in python?

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.

How do you add value to a tuple?

You can not add, change, remove items (elements) in tuples. tuple represent data that you don't need to update, so you should use list rather than tuple if you need to update it. However, if you really need to update tuple , you can convert it to list , update it, and then turn it back into tuple .

Can function return multiple values?

Even though a function can return only one value but that value can be of pointer type. ... If we want the function to return multiple values of same data types, we could return the pointer to array of that data types. We can also make the function return multiple values by using the arguments of the function.

How do you return more than one value?

Returning multiple values Using pointers: Pass the argument with their address and make changes in their value using pointer. So that the values get changed into the original argument. Returning multiple values using structures : As the structure is a user-defined datatype.

How do I return multiple values in flask?

1. Flask views can't return a tuple. You probably want to pass those as arguments to a template. – Morgan Thrapp Sep 29 '16 at 14:12.
2. Flask view functions can return multiple values but not in the way you want to use them here. See #4 in the documentation here. – A Poor Dec 17 '20 at 21:22.
