Python learns the -5.python of variables and data types and the segmentation and connection of strings

In Python, the variable type is fixed and cannot be modified once it is declared (in Python it should not be declared, but should be used)

That's right:

1 var = 12print(Var)3 var = 24print(VAR)

Output variable var values, 1 and 2 in turn.

Error:

1 var = 12print(Var)3" I am a variable "4  Print(VAR)

Compile errors, error on the third line.

Data types in Python:

Boolean	Isclosed=true
Integer	Age=18
Float	height=1.70
String	message= "Hello World" or message= ' Hello World '
List	list=[1,2,3,4,5]
Tuple	Tuple= (1,2,3,4,5)
Dict	dict={' Tom ': ' Lily ': 20}
Set	Set=set ([1,2,3,4,5])

Note: A tuple is a simplified list that cannot be modified once it is initialized. Set is a collection, and elements cannot be duplicated.

A string in Python.

Declaring a string in Python can be in single or double quotes:

1 ' Hello ' 2 " Hello " 3 Print (VAR==VAR2)

The output is true.

Segmentation of Strings:

1 ' I am tom\n, and you? ' 2 words = var.split ()3print(words)

The output will be

['I'am'Tom', and'you? ' ']

Python By default splits strings by spaces and line breaks

The connection of the string:

1 words = ['I','am','Tom'  ]2". Join (words)3print(str)

The output:

I am Tom
