Safe Dictionary Access with .get()

Snippet

The .get() method is a safer way to retrieve values from a dictionary because it returns 'None' (or a default value) if the key does not exist.

snippet.py
python
user = {"name": "Bob"}
 
# Returns None instead of raising a KeyError
email = user.get("email")
print(f"Email: {email}")

Breakdown

user = {"name": "Bob"}

Creates a dictionary with one key-value pair.

user.get("email")

Attempts to find 'email'. Since it's missing, it returns None without crashing.
