Grade statistics in functions

Task

Split the program into three functions:

nacitaj_znamky(text) gets a string of grades separated by spaces (for example "1 3 2 1") and returns them as a list of whole numbers,
priemer(znamky) returns the average grade rounded with round to 2 decimal places,
pocet_jednotiek(znamky) returns how many ones the list contains.

Under if __name__ == "__main__": the program reads a line of grades and prints:

Priemer: 1.75

Jednotky: 2

(for the input 1 3 2 1).

Examples

Input
```
1 3 2 1
```
Expected output
```
Priemer: 1.75
Jednotky: 2
```

Call

print(nacitaj_znamky("1 3 2 1"))

Expected output

[1, 3, 2, 1]

After you submit, 5 hidden tests will also check your solution: the average, an average with a half, no ones, all ones, one grade.

You need to know

Python starts the first time you run code.

def nacitaj_znamky(text):
    pass
def priemer(znamky):
    pass
def pocet_jednotiek(znamky):
    pass
# Kód pod touto podmienkou sa spustí, keď program spustíš ty. Testy ho preskočia
# a tvoje funkcie zavolajú priamo.
if __name__ == "__main__":
    znamky = nacitaj_znamky(input())
    print("Priemer:", priemer(znamky))
    print("Jednotky:", pocet_jednotiek(znamky))

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

Input (stdin)

Each line = one call to input().

Hints

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.
