#1. Expressions Inside Braces
name = "Alice"
age = 30
print(f"{name} is {age + 1} years old next year.")


#2. Calling Functions
def greet(name):
    return f"Hello, {name}!"
print(f"{greet('Bob')}")


#3. Format Specifiers
price = 49.99
print(f"The price is {price:.2f} dollars.")


#4. Dictionary Values
person = {'name': 'Alice', 'age': 30}
print(f"{person['name']} is {person['age']} years old.")


#5. Date Formatting
from datetime import datetime
now = datetime.now()
print(f"The current time is {now:%Y-%m-%d %H:%M}.")


#6. Multiline F-strings
name = "Alice"
profession = "developer"
bio = (f"Name: {name}\n"
       f"Profession: {profession}")
print(bio)
