Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given compound statement are:
4 < 3 and 5 < 10
4 <3 or 5 < 10
not (5 > 13)
4 < 3 and 5 < 10 this statement is false because "and" logical operator required that both operand (4<3) and (5<10) are true. Statement (4<3) is a false statement so this statement is false. "and" operator becomes true when all its inputs are true otherwise it becomes false.
4 < 3 or 5 < 10 this statement is true because "or" logical operator to be true if one of its input is true and false when all inputs are false. so in this compound statement, the first statement is false and the second statement is true. so this compound statement is true.
not(5>13) this compound statement is true because it has "not" operator and "not" operator makes a false statement to true and vice versa. so (5>13) is a false statement, and when you append "not" operator before it, then this compound statement will become true statement, so this is a true statement.
Answer:
true because it changes depending upon what you were doing so true
Answer:
1. get the absolute path to the file
2. load the file as a table (dataframe in python)
3. to insert a row;
- create a dataframe of the same field type
- concatenate the new dataframe horizontally with the same dataframe
4. to delete a row, select and drop the row where the 'Number' field matches a value.
5. to update the values in row, use the number field as a key to replace the existing values.
6. print of save to a variable the rows where the number field matches a given value.
Explanation:
Follow the report template to create a report for the algorithm.
The algorithm gets the absolute path to the file and loads the file as a tabular file from there the data can be queried without accessing the main file. The insert algorithm creates a new dataframe and appends it to the main dataframe.
The delete, update and retrieve all use the same subalgorithm, getting the rows with the number field as the key value.
