Get Excel-Style Column Names from Column Number

Question

This is the code for providing the COLUMN name when the row and col ID is provided but when I give values like row = 1 and col = 104, it should return CZ<

Answer 1

I think it is something like this :

def get_col(col):
    """Get excel-style column names"""
    (div, mod) = divmod(col, 26)
    if div == 0:
        return str(unichr(mod+64))
    elif mod == 0:
        return str(unichr(div+64-1)+'Z')
    else:
        return str(unichr(div+64)+unichr(mod+64))

Some tests :

>>> def get_col(col):
...     (div, mod) = divmod(col, 26)
...     if div == 0:
...         return str(unichr(mod+64))
...     elif mod == 0:
...         return str(unichr(div+64-1)+'Z')
...     else:
...         return str(unichr(div+64)+unichr(mod+64))
... 
>>> get_col(105)
'DA'
>>> get_col(104)
'CZ'
>>> get_col(1)
'A'
>>> get_col(55)
'BC'
