def f(x):
    if isinstance(x, list):
        result = []
        for y in x:
            for part in y.split(','):
                if '-' in part:
                    a, b = part.split('-')
                    a, b = int(a), int(b)
                    result.extend(range(a, b + 1))
                else:
                    a = int(part)
                    result.append(a)
        else: 
        result = x
    
    return result


cols = ['code1','code2']
df[cols] = df[cols].applymap(f)
print (df)
