   print() shows output = Displays text or values on the screen [OK]

Hint: Remember: print() shows output on screen [OK]

Common Mistakes:

• Thinking print() saves data
• Confusing print() with input()
• Assuming print() creates variables

2. Which of the following is the correct syntax to print "Hello, World!" in Python?

easy

A. printf("Hello, World!")

B. print(Hello, World!)

C. echo "Hello, World!"

D. print("Hello, World!")
