The def keyword in Python is used to define the function. Here, the hello_world function is defined to return the string “Hello. World!!”. Then, the print function calls ‘hello_world’, and the return string is printed as output.

Hello World Program in Python Using a Lambda Function

Output

The lambda function in Python is anonymous and can take any number of arguments but have only one expression. Here, the lambda function takes no arguments but returns “Hello, World!!”. Then, the print function calls the function and prints its return value.

Hello World Program in Python Using a Class

Output

The above program is quite an advanced level program. Here, we have used the concept of class in Python, which you will learn later.
Here, the ‘First_Program’ class is defined with a print message method that prints the ‘Hello, World!!’.
