Numeric Data Types
▪Numeric data types represent numeric data such as integers, floating point
or complexnumbers
▪Objects that store numerical type of data come under this category
Numeric
int float complex

3. Python Programming Specialization
Python Programming –Data Structures
Data Type: int

4. Python Programming Specialization
Python Programming –Data Structures
Numeric Data Type: int
▪Integersare represented by intclass
▪Integers are the whole numbers without any fractional part
▪Can be positive or negative numbers
▪In Python, Integers can be of any length
▪It’s length is restricted to the system memory

5. Python Programming Specialization
Python Programming –Data Structures
Numeric Data Type: int
▪Examples:
>>> a = 10
>>> b = 100
>>> c = 11111
>>> d = 3333
>>> e = 234257843112578886

Integers with other bases

7. Python Programming Specialization

<class int>: Binary data
▪Binary: Integers with base 2
▪Binary digits followed by 0bor 0Bare treated as binary in
python
>>> a = 0b101 #binary
>>> b = 0B100 #binary
Note: a is 5 and b is 4

8. Python Programming Specialization
Python Programming –Data Structures
<class int>: Octal data
▪Octal: Integers with base 8
▪Integers (0-7)followed by 0oor 0Oare treated as octal in
python
>>> c = 0o231 #octal
>>> d = 0O347 #octal
Note: C is 153 and d is 231

9. Python Programming Specialization
Python Programming –Data Structures
<class int>: Hexa-decimal
▪Hexa-decimal: Integers with base 16
▪Integers (0-9, A, B, C, D, E, F) followed by 0xor 0Xare treated as
octal in python
>>> e = 0x23 #hexa
>>> f = 0X3A # hexa
Note: e is 35 and f is 58

10. Python Programming Specialization
Python Programming –Data Structures
Data Type: float

11. Python Programming Specialization
Python Programming –Data Structures
Numeric Data Type: float
▪Real numbers are treated as float class
▪Contains both integer and fractional part
▪Can be positive or negative numbers
▪Python floating precision numbers are accurate upto15 decimal places
▪Eitherfloating point representation orscientific representation is valid in
python

12. Python Programming Specialization
Python Programming –Data Structures
Numeric Data Type: float
▪Examples:
>>> a = 2.3
>>> b = 100.0
>>> c = 0.5e+7
>>> d = 0.00e-4
>>> x = 0.30000000000000004

13. Python Programming Specialization

Complex Numbers

14. Python Programming Specialization
Python Programming –Data Structures
Numeric DataType: complex
Numerals with real and imaginary parts are treated as complex class
General Form: (real part) + (imaginary part)j
Ex: -5 + 3j
