One effective method often used by programmers to comprehend the effect of code is "tracing". Tracing is hand-executing the code in the same sequence and manner that the computer would execute the program. Often, the changes made to variables in the code are recorded in a "trace table". Each row in the trace table records the values of the variables after a corresponding statement in the left hand column of the trace table has been hand-executed. For example, for the code holden 2 ford13 mitsubishi = 5 a completed trace table would be: holden ford mitsubishi holden = 2 ford 13 mitsubishi = 5 13 2 13 Your task is to trace execution of the following Python code and keep track of variables index and minimum: results= [7, 3, 7] pass-grade = 4 minimum = 7 index = 0 if results[index] >= pass-grade and \ results [index] minimum : minimum results [index] index = index + 1 if results (index] pass grade and results[index) minimum minimum = results [index index = index + if results(index] > pass-grade and \ results [index)
