Iterate Through a Tuple in Python

Unpacking in Python refers to assigning values of a list or a tuple to variables using a single line of code. In this article, we will learn how to unpack a tuple in a for loop using Python.

Unpack a Tuple in a for Loop in Python

We can use Python’s unpacking syntax to unpack a tuple in a for loop. The syntax for the unpacking is as follows.

x1, x2, ..., xn = <tuple of length n>

The number of variables on the left side or before the equals sign should equal the length of the tuple or the list. For example, if a tuple has 5 elements, then the code to unpack it would be as follows.

a = tuple([1, 2, 3, 4, 5])
x1, x2, x3, x4, x5 = a



We can use the same syntax to unpack values within a for loop. Refer to the following Python code for the same.

a = tuple([
    ("hello", 5), 
    ("world", 25), 
    ("computer", 125), 
    ("science", 625), 
    ("python", 3125)

for x, y in a:
    print(f"{x}: {y}")


hello: 5
world: 25
computer: 125
science: 625
python: 3125

Each value tuple inside the parent tuple is unpacked in variables x and y.
