Incoming text may contain surrounding whitespace or mixed case. strip() trims the ends; lower() normalizes case. split() returns a list of parts, and join() combines strings with your chosen separator.

Raw text

Trim and normalize

Split into parts

Join the result

Python

raw = "  Python,HTML,CSS  "
clean = raw.strip().lower()
parts = clean.split(",")
print(parts)
print(" | ".join(parts))
print("python" in clean)
print(clean.replace("html", "javascript"))

What's the output?

print("  sea code  ".strip().upper())
