Explain the string concatenation and string replication operator with an example.

Python allows operators like + and * to behave differently depending on the type of data they are used with. For strings, these operators are used for:

(A) String Concatenation (+ Operator):

• The + operator joins (concatenates) two strings.
• It creates a new string that is the combination of the two.

Syntax:

string1 + string2
Example:

name = "Alice"
greeting = "Hello, " + name
print(greeting)

Output: Hello, Alice

Note: You cannot concatenate a string with a number directly. You must first convert the number to a string using str().

age = 20
print("Age: " + str(age))  # Correct

(B) String Replication (* Operator):

• The * operator repeats a string multiple times.
• It requires one operand to be a string and the other to be an integer.

Syntax: string * number

Example:

pattern = "Ha"
laugh = pattern * 3
print(laugh)

Output: HaHaHa
