Python_G-003 : Variable Type

Variable Type	Description	Example
int	integer	-3, 0, 34, ...
float	real	-23.43, 4.56 ...
str	string	"hello"
bool	True or False	True or 1 , False or 0
list	sequence	[1, 2, 3, 'four', 5.3]
tuple	sequence	(1, 2, 3, 'four', 5.3)
dict	sequence	{'key': 'value'}   ex)  {'name': 'Alice', 'age': 30, 'profession': 'Engineer'}
set	sequence	{1, 2, 3, 'four', 5.3}

 

 

List vs (1D) array

Type	Built-in Python data type	Provided by the NumPy library
Flexibility	Can contain elements of different types	Typically contains elements of a single data type
Operations	General-purpose operations (appending, slicing)	Optimized for numerical operations (element-wise operations, mathematical functions)
Performance	Generally slower for numerical operations	Generally faster and more efficient for numerical operations
Syntax	my_list = [1, 2, 3, 4, 5]	import numpy as np my_array = np.array(  [1, 2, 3, 4, 5]  )
