Python Literals

A literal is a value you write as-is in the source. 10 is an int literal. 3.14 is float. "Asha" is a string. True and False are booleans. None means no value. You are not computing them — you are writing the value itself.

Collections have literals too: [1, 2] list, (1, 2) tuple, {1, 2} set, {"name": "Asha"} dict. 2+3j is a complex literal. Interviewers want one example each: int, str, bool, None. That is enough.

Python Literals — output — 10, Asha, True, None. Four real literals.

Exam tip

One example each: int, str, bool, None.

Example

# Literals
print(10)
print("Asha")
print(True)
print(None)

Python Literals — output: 10, Asha, True, None. Four real literals.

Short notes

DefFixed value written in code.
Rule10, "hi", True, None.
RememberList/dict literals too.
