Summing numbers from a file

Task

The file cisla.txt has one whole number on each line. The program should print their sum. Fill in ___.

After you submit, 3 hidden tests will also check your solution: a single number, negative numbers, an empty file.

You need to know

Python starts the first time you run code.

sucet = 0
with open("cisla.txt") as f:
    for riadok in f:
        sucet += ___(riadok)
print(sucet)

Ctrl+Enter runs the program. Tab indents. Press Esc, then Tab, to leave the editor.

Input (stdin)

Each line = one call to input().

Try it yourself first. Each hint reveals a little more - and lowers the reward a little.

Signed out, hints are free - but no XP is awarded either.

Solution

The solution unlocks after the last hint.
