String Processing

Before reading files, let's practice string processing.

Common String Methods

Method	Description
.strip()	Remove whitespace
.split(",")	Split by delimiter
.lower()	Lowercase
.replace(a, b)	Replace a with b

Example: Parse CSV line

line = "John,25,Engineer"
parts = line.split(",")
name = parts[0]  # "John"
age = int(parts[1])  # 25

Your Task

Given the string data = "Product:Laptop,Price:999,Stock:50", extract and print just the price (as a number).
