Python Program to Find Sum, Maximum and Minimum of a List
mediumListsPython
Reading a whole line of numbers into a list is a pattern you will use in almost every list program.
The question
Read a line of integers separated by spaces into a list. Print the sum, then the maximum, then the minimum — each on its own line.
The code
program.py
nums = list(map(int, input().split()))
print("Sum =", sum(nums))
print("Maximum =", max(nums))
print("Minimum =", min(nums))Input
13 51 16 78 53 53 24
Output
Sum = 288 Maximum = 78 Minimum = 13
How it works
- 1input().split() breaks "4 7 2" into ["4", "7", "2"].
- 2map(int, …) converts each piece to a number; list(…) turns the result into a list.
- 3sum(), max() and min() are built-in functions that work on any list of numbers.
Common mistakes
- Skipping map(int, …) — max(["9", "10"]) compares text and says 9 is bigger.
- Naming your list sum or max, which hides the built-in function.
