How to Extract Digits from an Integer?

Extracting Digits from an Integer

How can you break down an integer into a list of its individual digits? For instance, transforming 12345 into [1, 2, 3, 4, 5].

Solution

To achieve this conversion, follow these steps:

1. Convert Integer to String: Convert the input integer to a string, which allows you to iterate through its characters.
2. Extract Digits: Inside a list comprehension, iterate over each character in the string.
3. Convert Digits to Integers: Each character represents a digit. Convert it back to an integer using the int() function.

Here's a Python implementation:

<code class="python">[int(i) for i in str(12345)]</code>

Example

Using the provided input of 12345, the code will execute as follows:

1. Convert 12345 to '12345'.
2. Iterate through characters: '1', '2', '3', '4', '5'.
3. Convert each character to an integer: [1, 2, 3, 4, 5].

Result: [1, 2, 3, 4, 5]
