Sample RBSE SS Computer Science Practice Questions

Try these sample questions to review concepts for the RBSE SS Computer Science exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In Python, which statement correctly describes a list?
A.It is an unordered collection of unique keys mapped to values
B.It is an ordered, mutable sequence that may contain duplicate elements
C.It is an immutable sequence of characters only
D.It is a fixed-size array that cannot grow after creation
Explanation: Lists are ordered and mutable sequences; elements may repeat and can be of mixed types. Dictionaries map keys to values; strings are immutable character sequences; Python lists grow dynamically.
2What is the output of: print(type((5,)) == type((5))) ?
A.True
B.False
C.TypeError
D.None
Explanation: (5,) is a one-element tuple; (5) is just the integer 5 in parentheses. Their types are tuple and int, so equality of types is False.
3Consider: s = {1, 2, 2, 3} print(len(s)) What is printed?
A.4
B.3
C.2
D.Error
Explanation: Sets store unique elements only, so {1, 2, 2, 3} becomes {1, 2, 3} with length 3.
4Which Python operator performs floor division and returns an integer-like result for ints?
A./
B.%
C.//
D.**
Explanation: The // operator is floor division (e.g., 7 // 2 == 3). / is true division, % is remainder, ** is exponentiation.
5Consider: for i in range(1, 5, 2): print(i, end=' ') What is printed?
A.1 2 3 4
B.1 3
C.1 3 5
D.2 4
Explanation: range(1, 5, 2) yields 1, then 3 (start 1, stop exclusive 5, step 2). Output: '1 3 '.
6What does the expression list('AB') evaluate to?
A.['AB']
B.['A', 'B']
C.('A', 'B')
D.Error
Explanation: list() on a string iterates characters, producing ['A', 'B'].
7Consider: def f(a, b=2): return a * b print(f(3)) What is printed?
A.6
B.3
C.TypeError
D.None
Explanation: b defaults to 2 when omitted, so f(3) returns 3 * 2 = 6.
8In Python, which keyword is used to create an anonymous function?
A.def
B.lambda
C.anon
D.func
Explanation: lambda creates a small anonymous function expression, e.g., lambda x: x+1.
9Consider: t = (10, 20, 30) print(t[1:]) What is printed?
A.(10, 20, 30)
B.(20, 30)
C.[20, 30]
D.20
Explanation: Slicing a tuple from index 1 to the end yields the tuple (20, 30).
10Which built-in function returns the number of items in a list, string, or dictionary?
A.count()
B.size()
C.len()
D.length()
Explanation: len(obj) returns the number of items (or characters for strings). count is a method on some sequences; size/length are not the standard builtins.
