STRING AND STRING ARRAY IN PYTHON

String

• In computer programming, a string is a sequence of characters. 
• The variable is initialized with the string Python Programming.
• The string is collection of alphanumeric letters and special characters.
• A string is a collection  of alphabets ('a' to 'z' and 'A' to 'Z'),numbers (0 to9),spaces and spe6 characters.
• string value is enclosed by single or double or triple quotes The flexibility of using different quotes is to use the other quotes as part of the string value.
• The main restriction is same quote should be used at beginning and end of the string to denote the string value.

String Usage:

Strings are used for storing text/characters.

 Example: 

    "Hello World" is a string of characters.

 Types Of String:

• Char
• Varbinary
• Blob 
• Text
• Set
• Enum

Creating Strings:

• A string in python can be created using single or double or even triple quotes
• String in single quotes cannot hold any other single quotes character in it, because the compiler will not recognise where to start and end the string.
• To overcome this problem you have to use double quotes. 
• String which contains double quotes should be define within triple quotes Defining strings within triple quotes also allows creation of multiline strings.

Program:

  

  # Prompt the user to enter a string

  input_str = input("Enter your name: ")

 

  # Print the string to the console

  print("Your name is :", input_str)

Output:

  

  Enter your name: Siva

  Your name is :Siva

String And String Array

• String is a data type in python ,which is used to handle array of characters.
• String is a sequence of Unicode characters that may Be combination of letters,  numbers, or special symbols enclosed within single ,double or even triple quotes. strings are immutable ,it means,once you define a string,it cannot be changed during execution.
• String Array can be defined as the capacity of a variable to contain more than one string value at the same time, which can be called and accessed at any time in the program during the execution process. 
• A String Array is an Array of a fixed number of String values.
•  A String is a sequence of characters. Generally, which means the value of the string can not be changed.
•  The String Array works similarly to other data types of Array. In Array, only a fixed set of elements can be stored. 
• The key difference between Array and String is that an Array is a data structure.

Program:

  

  # Create an array of strings

  string_array = ["apple", "banana", "cherry", "elderberry"]

  # Print each string in the array to the console

  for string in string_array:

      print(string)

Output:

  

  apple

  banana

  cherry

  elderberry
