Chapter 4: Problem 15

What will the following code display? total = 0 for count in range(1, 6): total = total + count print(total)

Short Answer

Expert verified
Answer: The final output of the given code is 15.

Step by step solution

01

Identify the variables used in the code

In the code, two variables are used: 'total' and 'count'. The 'total' variable is initialized to 0, while the 'count' variable is used in the for loop and it will change its value in each iteration.
02

Understanding the for loop with range function

In the code, a for loop is used, with the range function (range(1, 6)). The range function generates a sequence of numbers from the given start value (1) to the end value (6) with a step of 1, excluding the end value itself (it will generate numbers 1, 2, 3, 4, 5). The for loop will iterate through the numbers generated by the range function, and in each iteration, it will assign the next number in the sequence to the variable 'count'.
03

Analyzing the operation inside the for loop

Inside the for loop, there is an assignment statement "total = total + count". In each iteration, it adds the current value of 'count' to the value of 'total' and then assigns the result to 'total'. This operation continues until the for loop has iterated through all the numbers generated by the range function.
04

Understanding the print statement

After the for loop, there's a print statement (print(total)), which prints the final value stored in the variable 'total'.
05

Predicting the output

The code will execute as follows: 1. Initialize the 'total' variable to 0. 2. Iterate the for loop with 'count' having the values 1, 2, 3, 4, and 5. 3. In each iteration: a. Add the current value of 'count' to the value of 'total'. b. Assign the result to 'total'. 4. After all iterations, the 'total' variable will store the sum of all integers from 1 to 5 (1 + 2 + 3 + 4 + 5 = 15). 5. Print the final value of 'total'. The output displayed will be: 15
