Understanding Multiple Choice Quiz About Python

• Question 1: What is the result of the following expression?

  chr ('97')
  chr (97)

  • a Lỗi
  • 'a' a
  • Lỗi a
  • Lỗi Lỗi
  Explanation: The chr () function returns the letter corresponding to the value provided as a parameter. This function only accepts integer type values. In the first function, we passed a string. Therefore the first function returns an error.
• Question 2: What is the result of the following function?

  complex (1+2j)

  • Lỗi
  • first
  • 2j
  • 1 + 2j
  Explanation: complex () function returns results in complex numbers.
• Question 3: Where are the results of complex () function in the answers below?
  • 0j
  • 0 + 0j
  • 0
  • Lỗi
  Explanation: The complex () function returns 0j if both parameters are omitted, meaning that if the function is in complex () or complex (0), the output will be 0j.
• Question 4: Divmod function (a, b) where 'a' and 'b' are integers interpreted as:
  • (a% b, a//b)
  • (a//b, a% b)
  • (a//b, a * b)
  • (a/b, a% b)
  Explanation: The divmod (a, b) function is interpreted as a//b, a% b if both 'a' and 'b' are integers.
• Question 5: What is the output of the representation function below?

  divmod (10.5,5)
  divmod (2.4,1.2)

  • (2.00, 0.50) (2.00, 0.00)
  • (2, 0.5) (2, 0)
  • (2.0, 0.5) (2.0, 0.0)
  • (2, 0.5) (2)
  Explanation: The divmod () function in Python returns a tuple including quotient and balance when parameter 1 is divided by parameter 2.
• Question 6: Is the following statement true or false?The expression complex ('2-3j') is valid and complex ('2 - 3j') is the wrong syntax of the complex () function.
  • It's correct
  • False
  Explanation: When converting from a string, the string must not contain any spaces around the + or - operator. Therefore, complex function ('2 - 3j') will lead to an error.
• Question 7: What is the result of the function shown below?

  list (enumerate ([2, 3]))

  • Lỗi
  • [(1, 2), (2, 3)]
  • [(0, 2), (1, 3)]
  • [(2, 3)]
  Explanation: The enumerate () function accepts iterable as a parameter, in case the function requires returning an array list with its index starting from 0. Therefore, the output will be: [(0, 2), (1,3)].
• Question 8: What is the result of the function shown below?

  x=3
  eval ('x^2')

  • Lỗi
  • first
  • 9
  • 6
  Explanation: The eval function is used to evaluate the expression it uses as a parameter. In the above case, the eval () function is used to perform the XOR operation between 3 and 2. Therefore the output is 1.
• Question 9: What is the output of the following function?

  float ('1e-003')
  float ('2e+003')

  • 3.00 300
  • 0.001 2000.0
  • 0.001 200
  • Lỗi 2003
  Explanation: The output of the first function will be 0.001 and the second function will be 2000.0. The first function creates a number of floating points up to 3 decimal places and the second function adds three zeroes after the given number.
• Question 10: Which of the following functions does not accept iterable as a parameter?
  • enumerate ()
  • all ()
  • chr ()
  • max ()
  The functions enumerate (), all () and max () accept iterable as a parameter while the chr () function will get an error when receiving iterable as a parameter. Also note that the chr () function only accepts integer values.
