Question

This is a Python function. It’s convert to a list of words from a string. But I don’t understand the algorithmic the part of code:

for c in ch:
        if c==" ":
            lista.append(ct) # add to list of temporary string
            ct=""            # the ch temporary string reinicialization

I don’t understand, how the ct can append to the list, because the ct=””? How casn it get value?

Thanks for the help!

Here the full code of function:

def szoLista(ch):
    "a ch karakterláncot átalakítja szavakból álló listává"
    lista, ct=[],""     # ct átmeneti string
    for c in ch:
        if c==" ":
            lista.append(ct) # a listához adjuk a ch átmenei stringet
            ct=""            # a ch átmeneti string reinicializálása
        else:
            ct=ct+c
    if ct !="":
        lista.append(ct)    # az utolsó szó hozzáadása
    return lista

Answer 1

else:
    ct=ct+c

These are the lines you are overlooking.
ct is set empty when a space if found, but after it was already added to the list.
If the current character is not a space, the character is appended to ct.
So when you encounter the next space, you have the last word in ct and can add it to the list.
