Python Intro Part 2

This line of code uses the input() function to prompt the user to enter their name and stores the result of the input in the name variable.

• Programming Concept:  Input is the process of getting information from the user or other data sources. By interacting with the user through the input() function, the program is able to perform specific actions based on the information provided by the user. This makes the program more flexible and dynamic.

In this line of code, the input() function is used to prompt the user to enter their year of birth. The value returned is in string format, so we use the int() function to convert it to an integer so that we can perform arithmetic operations.

• Programming Concept:  Type conversion is the process of converting one data type (such as string, integer, floating point number, etc.) to another data type. Make sure the input data type is suitable for subsequent calculations and operations. Here, converting the string to an integer is necessary because we need to perform subtraction to calculate the age. Failure to convert may result in errors or incorrect results.

This line of code calculates the user's age using a simple subtraction operation. It subtracts the user's birth year (stored in the year variable) from the current year (2024) and stores the result in the age variable.

• Programming Concept:  Arithmetic operations are basic math operations performed on numbers, including addition (+), subtraction (-), multiplication (*), and division (/). Here, we use subtraction to calculate the user's age. The program uses simple math to get the result.

The final line uses the print() function to output a message that includes the user's name and age.

• Programming Concept:  Output is the process of displaying data or information from a program to the user. The print() function provides a way to communicate with the user so that the program can provide feedback.
