I/O and Documentation

Download Python.


Write a program to add two numbers and print the result. Numbers will be space separated on a single line (see the sample input and output below). You may copy-paste the below example if you understand it.

nums = input().split()
total = int(nums[0]) + int(nums[1])

Or, for those who are more experienced, a one-line solution is:

print(sum(map(int, input().split())))


  • Go to the submit tab and upload the addition program above by copy-pasting and selecting Python in the language dropdown.
  • Do not use input prompts e.g. input("Numbers: ") because the string "Numbers: " will be evaluated as incorrect output. See the walk-through below to understand why.
  • Walk-through example and explanation.
  • Understanding submission feedback.

Note: There are two submission options for Python programs. You may select Python 3.8 or Python 3.6 (PyPy 7.3). PyPy is a just-in-time compiler which is often faster than the standard C Python interpreter. The compromise is the older version of Python. Newer NZIC problems should be solvable with C Python (unless specified) but other problems on this site might not be. If your Python solution is timing out it might be worth trying PyPy.
