Literals in Python | String Literals | Numeric Literals| Boolean Literals| Literal None| CBSE Python
In this Python tutorial for beginners, we will learn literals in Python. This Python tutorial video covers: What is a literal in python?, Types of Literals in Python:
1. String literals
2. Numeric literals
3. Boolean literals
4. Special literal None
5. Literal collections
String literals: single line string, multi-line strings, raw string.
String literals using single quotes, double quotes, and triple quotes.
String literals using escape characters.
How can we use a quote inside a string?
Numeric literals: In Python, there are three types of numeric literals:
1. integers (or int),
2. floating point numbers (or float),
3. imaginary numbers.
Python supports 4 types of integer literals:
1. Decimal Integer literals
2. Binary integer literals
3. Octal integer literals
4. Hexadecimal integer literals
Floating-point literals: Floating-point literals or real literals contain a decimal point or an exponent or both.
The floating-point literals may also be expressed in exponential notation.
Imaginary literal: An imaginary number is a real number multiplied by the square root of -1.
A complex number is a combination of a real and an imaginary number.
Boolean Literal: A Boolean literal in Python has two values, i.e., either True or False.
Special Literal None: In Python, “None” is a special literal that represents the absence of a value.
Literals collections: Python supports four types of literal collections, such as tuples, lists, dicts, and set literals.
