Step 1: Create two variables, name, and age, and use the input() function to get user input.

name = input("What is your name? ")
age = input("What is your age? ")

Step 2: Use the int() function to cast the variable age from a String data type to an integer data type.

age = int(age)

Step 3: Print a greeting containing the user’s name and age. Use the format method to insert the variables.

print("Hello {}, your age is {}".format(name, age))

Step 4: Create an if-else statement to check if the user is old enough to purchase an alcoholic beverage and print an appropriate message.

if age >= 21:
    print("You can buy an alcoholic beverage")
else:
    print("You cannot buy an alcoholic beverage")

Full Code

name = input("What is your name? ")
age = input("What is your age? ")

age = int(age)

print("Hello {}, your age is {}".format(name, age))

if age >= 21:
    print("You can buy an alcoholic beverage")
else:
    print("You cannot buy an alcoholic beverage")
