The tradition is “Hello, World!” — the simplest program that verifies your environment works.

print("Hello, World!")

Output:

Hello, World!

name = input("What's your name? ")
age = int(input("How old are you? "))
print(f"\nHello, {name}!")
print(f"In 10 years, you'll be {age + 10} years old.")

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

# sep — separator
print("a", "b", "c", sep="-")    # a-b-c

# end — what to print at end
print("Hello", end="")            # No newline

# file — output to file
with open("output.txt", "w") as f:
    print("To file", file=f)

Your first program establishes that your development environment is correctly set up, and introduces the most basic input/output operations.

Q1: What does print("a", "b", "c", sep="-") output?

A: a-b-c. The sep parameter controls how multiple arguments are separated.

Q2: How do you print without a newline?

A: print("text", end="") — set the end parameter to an empty string.

1. Print your name, age, and city using a single print statement.
2. Create a program that asks for your favorite color and prints a message.
3. Use print() with different sep and end combinations.
