Question

1. correct the third line of code so it will execute correctly in python: x=10 y=6 a=2(x+y) 2(x+y)=a a=(x+y)2 a=(2)(x+y) a=2*(x+y) 16. what processing usually needs to be done on a line after it has been read in? the line needs to be converted to uppercase. the carriage return and/or line feed needs to be stripped of the end of the line. the line needs to be converted from a string of integers to a string of letters. 17. what will this code print? a = true if a: print(\a\) else: print(\b\) print(\c\) a b c a c a nothing

Explanation:

Question 15:

In Python, to multiply a value by an expression in parentheses, an asterisk () for multiplication is required. So a=2(x + y) is the correct syntax.

Question 16:

When reading lines, especially from files, the carriage - return and/or line - feed characters (`
,
) at the end of the line are often unwanted and need to be removed using the strip()` method.

Question 17:

The variable A is set to True. In the if - else statement, since A is True, the code block under if A: will execute, printing "A". Then the line print("C") outside the if - else block will execute, printing "C".

Answer:

1. D. a=2*(x+y)
2. B. The carriage return and/or line feed needs to be stripped of the end of the line.
3. B. A C
