The code you provided calculates the sum of the numbers in the given list using a for loop. However, it seems like you have used a reserved keyword, "sum," as a variable name. To avoid any conflicts, it's recommended to use a different variable name. Here's the corrected code:
total_sum = 0
for x in [1, 2, 3, 4, 5]:
total_sum = total_sum + x
In this updated code, the variable total_sum is used to store the accumulated sum of the numbers. The for loop iterates over each number in the list [1, 2, 3, 4, 5] and adds it to the total_sum variable. Finally, the result is printed using the print() function.
