One Effective Method Often Used Programmers Comprehend Effect Code Tracing Tracing Hand E Q43827081
One effective method often used by programmers to comprehend theeffect of code is “tracing”. Tracing is hand-executing the code inthe same sequence and manner that the computer would execute theprogram. Often, the changes made to variables in the code arerecorded in a “trace table”. Each row in the trace table recordsthe values of the variables after a corresponding statement in theleft hand column of the trace table has been hand-executed.
For example, for the code
holden = 2
ford = 13
mitsubishi = 5
a completed trace table would be:
holden
ford
mitsubishi
holden = 2
2
–
–
ford = 13
2
13
–
mitsubishi = 5
2
13
5
Your task is to trace execution of the following Python code andkeep track of variables alarm, level and threshold:
alarm
level
threshold
level = 10
–
10
–
threshold = 10
–
10
10
alarm = 3
3
10
10
if level >= threshold:
-1012345678910100TrueFalse
-1012345678910100TrueFalse
-1012345678910100TrueFalse
if level< 100:
-1012345678910100TrueFalse
-1012345678910100TrueFalse
-1012345678910100TrueFalse
alarm= 1
-1012345678910100TrueFalse
-1012345678910100TrueFalse
-1012345678910100TrueFalse
alarm = 2
