Python List index out of range error while iterating through 2 lists in python

k11

New Coder
I have 2 Lists in my code.
data list is having len = 11
new_list is having len = 23

I have to search if a string from data list and check if it exists in new_list.
I can see that my target_data gets filled with data,but when i go to print it, I get an error..

My data list contents as below:

new_list contents
| block_ram_top | (top) | 23 | 23 | 0 | 0 | 138 | 0 | 2 | 0 | 4 |
| (block_ram_top) | (top) | 7 | 7 | 0 | 0 | 9 | 0 | 0 | 0 | 0 |
| blk_mem_inst_0 | blk_mem_gen_0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 |
| (blk_mem_inst_0) | blk_mem_gen_0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

The variable that i extract from the new_list in my code:
inst_blk_mem_gen']
gnbram.gnativebmg.native_blk_mem_gen']
valid.cstr']
ramloop[0].ram.r']
prim_noinit.ram']
blk_mem_inst_1']
U0']
block_ram_top']
blk_mem_inst_0']
complex_multiplier_inst']

Expected target_data list:
This should have all the data list items having the variable that i extract from the new_list items:

My code:
Python:
print len(new_list)
print len(data)
      
for i in range(len(new_list)):
    parts = (new_list[i].split('|'))
    #print parts
    if (int(parts[8]) >= 1 or int(parts[9])  >= 1 or int(parts[11])  >= 1 ):
        variable = parts[1]
        variable = variable.strip()
        variable = variable + "']"
        #print variable
        for d in data:
            if variable in d:
                target_data.append(d) 
                print "ok"
            else:
                NODATA = 1
    else:
        NODATA = 1
print target_data

Error:
