Create tuples using Python's tuple() function

Use Python’s tuple() function to create tuples

In Python, a tuple is an immutable sequence type. It is similar to a list, but cannot be modified in any way. You can create tuples by using the tuple() function. This article explains how to use this function to create tuples, along with some code examples.

1. Create an empty tuple
   Through the tuple() function, you can create an empty tuple. The sample code is as follows:

my_tuple = tuple()
print(my_tuple)

The output result is an empty tuple: ()

2. Create a tuple containing elements
   Use the tuple() function, you It is possible to create tuples containing some elements.

my_tuple = tuple([1, 2, 3, 4, 5])
print(my_tuple)

The output result is: (1, 2, 3, 4, 5)

You can also add multiple elements to the tuple at one time:

my_tuple = tuple(["apple", "banana", "orange"])
print(my_tuple)

The output result is: ('apple', 'banana', 'orange')

3. Tuple unpacking
   Tuple unpacking is to assign the elements in the tuple to multiple variables the process of. This operation can be easily accomplished using tuples created with the tuple() function.

my_tuple = tuple([1, 2, 3, 4, 5])
a, b, c, d, e = my_tuple
print(a, b, c, d, e)

The output result is: 1 2 3 4 5

In this way, we assign each element in the tuple to the variables a, b, c, d, e.

4. Tuple as function return value
   Using the tuple() function, you can combine some values ​​into a tuple and use them as the return value of the function.

def get_values():
    name = "John"
    age = 25
    country = "USA"
    return tuple([name, age, country])

result = get_values()
print(result)

The output result is: ('John', 25, 'USA')

In the above example, we combine name, age, country into a tuple, and use it as the return value of the function.

Summary:
This article introduces how to use Python’s tuple() function to create tuples. With this function, you can create empty tuples, tuples with elements, unpack tuples, and return tuples as function returns. Tuple is an immutable sequence type suitable for representing some unmodifiable data collection. Using the tuple() function, you can easily create and manipulate tuples.
