Practice by topic / Python & code / Python
Python is the most popular language for automating work: cleaning data, renaming files, crunching numbers. Each exercise runs your real code in the browser and checks it. These 5 exercises build up step by step, starting with tidy a name, get the email domain, check a prefix.

<code>raw</code> holds a messy customer name. Create <code>clean</code>: spaces trimmed from both ends and each word capitalised (<code>Tan Wei Ling</code>).
Chain two methods: clean = raw.strip().title()
Exactly — .strip() then .title() is the Python version of TRIM + PROPER in Excel.
Create <code>domain</code>: everything after the <code>@</code> in <code>email</code>.
domain = email.split("@")[1]
Right — split('@') breaks the text at the @, and [1] takes the part after it.
Create <code>is_invoice</code>: <code>True</code> if <code>code</code> starts with <code>INV-</code>, otherwise <code>False</code>.
is_invoice = code.startswith("INV-")
Good — .startswith() returns True or False directly, no if statement needed.
<code>phone</code> uses dashes. Create <code>fixed</code> with every dash replaced by a space.
