1. What is expandtabs() in Python?
The expandtabs() method in Python is a built-in string function that replaces every tab character (\t) in a string with spaces.
It is particularly useful for aligning text output, formatting tabular data, or handling tab-separated files where visual consistency matters.
Unlike a simple replace operation, expandtabs() gives you fine-grained control over how many spaces each tab should represent using the optional tabsize parameter.
In simple terms: it converts invisible \t characters into visible spaces — making text more readable and neatly aligned.
2. Purpose of Using expandtabs() Method

- In short, expandtabs() is ideal when clarity and alignment of text are important.
