Questions

1. What will print("Hello" + " " + "World") display?

   1. Hello World
   2. "Hello" "World"
   3. HelloWorld
   4. Error
   Show answer

   Answer: Hello World

   The + operator concatenates strings in Python. 'Hello' + ' ' + 'World' produces 'Hello World'.

2. Which of the following is a valid Python variable name?

   1. 2myVar
   2. my-var
   3. my_var
   4. my var
   Show answer

   Answer: my_var

   my_var is valid — it uses only letters and underscores. 2myVar starts with a number, my-var uses a hyphen, and my var has a space, all of which are invalid.

3. What data type is the value 3.14 in Python?

   1. integer
   2. string
   3. boolean
   4. float
   Show answer

   Answer: float

   3.14 is a floating-point number (float) because it has a decimal point. Integers have no decimal portion.

4. What does the following code output? for i in range(3): print(i)

   1. 1 2 3
   2. 0 1 2
   3. 0 1 2 3
   4. 1 2
   Show answer

   Answer: 0 1 2

   range(3) generates 0, 1, 2. Python's range starts at 0 by default and stops before the given number.

5. In Python, True and False must be capitalized.

   Show answer

   Answer: True

   Python is case-sensitive. 'true' and 'false' are not recognized as booleans — only 'True' and 'False' with capital first letters are.

6. Which symbol is used to write a comment in Python?

   1. //
   2. /*
   3. #
   4. --
   Show answer

   Answer: #

   The # symbol starts a comment in Python. // is used in JavaScript/C++, /* */ is for block comments in other languages, and -- is SQL.

7. What will the following code do? x = 5 if x > 3: print("big")

   1. Print nothing
   2. Print 'big'
   3. Print '5'
   4. Cause an error
   Show answer

   Answer: Print 'big'

   Since x equals 5 and 5 > 3 is True, the indented block runs and prints 'big'.

8. The keyword used to define a function in Python is ______.

   Show answer

   Answer: def

   The def keyword (short for define) is used to declare a function in Python, followed by the function name and parentheses.
