What means: TypeError: 'Row' object does not support indexing ???

rows1 = arcpy.SearchCursor(fc, ["SHAPE@"])
extents = []
for row1 in rows1:
    
    ext = row1[0].extent
    extents.append(row1[0].extent)
    print(extents)

setValue is replaced by updateRow, I can't find reference to setValue in the new data access cursors...I rarely use them but the error says that you are trying to use a setValue method on a list object, suggesting that row is a list ... you need to define the rows to use in this line

with arcpy.da.UpdateCursor(input_shp,['FID','SHAPE@'])

which you haven't, and then reference the column by an offset number ie row[0] would be the FID field and row[1] the SHAPE@ field as in the example I sent you.
Maybe someone who uses 'cursors' will weigh in...I have pretty well switched over to numpy arrays should I have the rare need to work with attributes.

cur.updateRow(row) doesn't work as well ?

Thought I wold get some information through def print attributes?

Your line numbers are off...any way

curs.updateRow(row) should be

cur.updateRow(row) there is no curs in the script you have shown

print_attributes(row) this function is define elsewhere?

you seem to be missing old cursors with new cursors, ie using setValue...you should be using updateRow as in the example here ie access the field by offset number for the row you are working with

Thats what I have so far with the help of dan and xander:

The goal is to create an oldschool image catalog as dbf, because we use a software which can't read the new ones.

Thank you

Examine this

import arcpy
input_shp = 'c:/folder/you_file_here.shp'
arr = arcpy.Array()
with arcpy.da.SearchCursor(input_shp,['FID','SHAPE@']) as cur:
  extents = [] 
  for row in cur:
    ext = row[1].extent
    p0 = ext.lowerLeft; p1 = ext.upperRight
    print('Extent of shape... {}: '.format(row[0]))
    print(' X min/max  {}, {}'.format(ext.XMin,ext.XMax))
    print(' Y min/max  {}, {}'.format(ext.YMin,ext.YMax))
    arr.add(p0)
    arr.add(p1)
mp = arcpy.Multipoint(arr)
print('Extent of all {}'.format(mp.extent))
