# Literal Constant, Escape Sequences

## Literal Constant

1. Number →  Integers, Floating, Complex numbers
2. Strings  →   Single character, Group of character

• ## Numbers

Integers → 3,5,7,100,350......

Floating point (Fractional) → 1.4, 5.6, 3.14, 2.3....

Complex numbers → a+ib, 5+3i......

Long integer → 'J' or 'L'
(12345678945L)

* There are three measure Problem in numbers system (You can get)

1. Arithmetic overflow Problem → If multiply two (*) long floating points numbers will be output infinity.
2. Arithmetic underflow Problem → (Division) → if the denominator is large than numerator than will be output zero (0).
3. Loss of Precession Problem →

•  Division EX:- 10/3= 3.33333333333...........Strings :- The strings can be represented any three quote
• Single quote → ( )
• Double quote → " "
• Triple quote → "'    "'

* Single quote and double quote are same (so we can represented)

Ex:- 'Python' (or) "Python"

* We have the use triple quote in a multiple strings

* If any strings represented if more than one line than that multi line strings can be used triple quote.

Ex:- "' Welcome To
Python Programming"'

## Escape Sequences:-

Printing Special Symbols on the screen you have to use these Escape Sequences (we will use back slash )

\'                      →           Single quote
\\                      →           Slash
\''                      →           Double quote
\n                      →          New Line
\t                       →          Tab Space
\o                               Octa value
\x                      →          Hexa value
