Which of the following control flow statements should the data engineer use to begin this conditionally executed code block?

A data engineer only wants to execute the final block of a Python program if the Python variable day_of_week is equal to 1 and the Python variable review_period is True.

Which of the following control flow statements should the data engineer use to begin this conditionally executed code block?
A . if day_of_week = 1 and review_period:
B . if day_of_week = 1 and review_period = "True":
C . if day_of_week == 1 and review_period == "True":
D . if day_of_week == 1 and review_period:
E . if day_of_week = 1 & review_period: = "True":

Answer: D

Explanation:

In Python, the == operator is used to compare the values of two variables, while the = operator is used to assign a value to a variable. Therefore, option A and E are incorrect, as they use the = operator for comparison.

Option B and C are also incorrect, as they compare the review_period variable to a string value "True", which is different from the boolean value True.

Option D is the correct answer, as it uses the == operator to compare the day_of_week variable to the integer value 1, and the and operator to check if both conditions are true. If both conditions are true, then the final block of the Python program will be executed.
