Strings are a type of data used in Python to represent text-based data. Strings can be manipulated and used in a variety of ways in Python.
To create a string in Python, enclose the text in quotation marks. For example:
my_string = “Hello World!”
To access individual characters in a string, use the index operator []. For example:
my_string[0] # returns ‘H’
To concatenate strings together, use the + operator. For example:
my_string = “Hello” + ” ” + “World!” # returns “Hello World!”
To repeat a string multiple times, use the * operator. For example:
my_string = “Hello” * 3 # returns “HelloHelloHello”
To find the length of a string, use the len() function. For example:
len(my_string) # returns 11
To search for a substring within a string, use the in operator. For example:
“World” in my_string # returns True
