I am trying to insert cols_code into the first row of excel starting from index 3 to 35.
For instance, if I do this: 

for k, x in enumerate(string.ascii_uppercase[2:35]): 

      ws[x + str(fr - 2)] = cols[k]

 It is inserting up to # 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' and I want beyond Z.

If I do this:

cols_code = ['CODE', 'P001', 'P001', 'P006', 'P006', 'P010', 'P010', 'P025', 'P025', 'P030', 'P030', 'P037' , 'P037', 'P050', 'P050', 'P060', 'P060', 'P106', 'P106', 'P045', 'P045', 'P080', 'P080', 'P085', ' P085', 'P095', 'P095', 'P101', 'P101', 'P108', 'P108', 'P120', 'P120'] 

for col in range ( 3 , 36 ): 
    print ( 'col' , col) 
    for i in cols_code: 
        print ( 'iiii' ,i) 
        ws[i + str (fr - 2 )] = cols_code[col]

It is giving me this error:
