Operators with the same precedence are evaluated in which manner?
- A.
Left to Right
- B.
Right to Left
Correct Answer
A. Left to RightExplanation
Operators with the same precedence are evaluated from left to right. This means that when there are multiple operators with the same level of precedence in an expression, the evaluation starts from the leftmost operator and continues towards the right. The operands are evaluated in the order they appear in the expression, and the result is obtained by performing the operations in the order they are encountered.Rate this question:

Print(“hello\example\test.txt”)
- B.
Print(“hello\\example\\test.txt”)
- C.
Print(“hello\”example\”test.txt”)
- D.
Print(“hello”\example”\test.txt”)
Correct Answer
B. Print(“hello\\example\\test.txt”)Explanation
The correct answer is print(“hello\\example\\test.txt”). This is because the backslash (\) is an escape character in Python, which is used to indicate special characters. In order to print a backslash itself, we need to use a double backslash (\\). So, the correct statement is the one that uses double backslashes to print the desired string.Rate this question:

- A.
\t\tWorld\n
- B.
\tWorld\n
- C.
\t\tWORLD\n
- D.
World
Correct Answer
D. WorldExplanation
The strip() method in Python removes leading and trailing whitespace characters from a string. In this case, the string s is "\t\tWorld" which has two leading tab characters. So, s.strip() will remove these tab characters and return the string "World".Rate this question:

What is the output of “hello”+1+2+3 ?
- A.
Hello123
- B.
Hello
- C.
Error
- D.
Hello6
Correct Answer
C. ErrorExplanation
The output of "hello"+1+2+3 would be "hello123" because when a string is concatenated with a number, the number is converted to a string and appended to the original string. Therefore, "hello" is concatenated with "1" to form "hello1", then "hello1" is concatenated with "2" to form "hello12", and finally "hello12" is concatenated with "3" to form "hello123". Hence, the correct answer is "hello123".Rate this question:

Python is case sensitive when dealing with identifiers?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Python is case sensitive when dealing with identifiers, meaning that it distinguishes between uppercase and lowercase letters in variable names, function names, and other identifiers. This means that variables named "myVariable" and "myvariable" would be considered as two separate identifiers in Python. Therefore, the answer "True" is correct.Rate this question:

The value of the expressions 4/(3*(2-1)) and 4/3*(2-1) is the same. State whether true or false.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The expressions 4/(3*(2-1)) and 4/3*(2-1) both involve the same mathematical operations: division, multiplication, and subtraction. According to the order of operations (PEMDAS/BODMAS), parentheses should be evaluated first, followed by multiplication and division from left to right. In both expressions, the parentheses are evaluated first, resulting in 4/(3*1) and 4/3*1, which simplifies to 4/3 and 4/3, respectively. Therefore, the value of both expressions is the same, making the answer "True".Rate this question:

The result of the expression given A % B // A, if A= 16 and B = 15 is ________
Correct Answer
Zero, zero, 0Explanation
The expression A % B // A can be broken down into two parts: A % B and the result of that divided by A. In this case, A = 16 and B = 15. When we calculate 16 % 15, the remainder is 1. Dividing 1 by 16 gives us 0.0625, but since we are using integer division, the decimal part is truncated and we are left with 0 as the final result. Therefore, the result of the expression is "Zero, zero, 0".Rate this question:
- 29.
The value of x is _______ if : x = int(43.55+2/2)
Correct Answer
44Explanation
The value of x is 44 because the expression inside the int() function is evaluated first. The expression 43.55 + 2/2 is equal to 44. The int() function then converts this decimal number to an integer, resulting in the value of x being 44.Rate this question:

What is the value of the following expression? : 2+4.00, 2**4.0
- A.
(6.0, 16.0)
- B.
(6.00, 16.00)
- C.
(6, 16)
- D.
(6.00, 16.0)
Correct Answer
A. (6.0, 16.0)Explanation
The expression 2+4.00 evaluates to 6.0 because adding an integer (2) to a float (4.00) results in a float. The expression 2**4.0 evaluates to 16.0 because the double asterisk (**) represents exponentiation, so 2 raised to the power of 4.0 equals 16.0. Therefore, the correct answer is (6.0, 16.0).Rate this question:
