Question

I would like to make a alphabetical list for an application similar to an excel worksheet.

A user would input number of cells and I would like to generate list. For

Answer 1

I've ended up doing my own. I think it can create any number of letters.

def AA(n, s):
    r = n % 26
    r = r if r > 0 else 26
    n = (n - r) / 26
    s = chr(64 + r) + s

    if n > 26: 
        s = AA(n, s)
    elif n > 0:
        s = chr(64 + n) + s

    return s

n = quantity | r = remaining (26 letters A-Z) | s = string

To print the list :

def uprint(nc):
    for x in range(1, nc + 1):
        print AA(x,'').lower()

Used VBA before convert to python :

Function AA(n, s)

    r = n Mod 26
    r = IIf(r > 0, r, 26)
    n = (n - r) / 26
    s = Chr(64 + r) & s

    If n > 26 Then
        s = AA(n, s)
    ElseIf n > 0 Then
        s = Chr(64 + n) & s
    End If

    AA = s

End Function
