Nested loop based number of filtered rows

[pradeepkumarbe]

My Csv File looks like below
Territory NoOfCustomer
D00060 10
D00061 20
D00065 70
D00067 90

I have to create a Unique Id based on Number of NoOfCustomer like If NoOfCustomer <=50
then I have to create 10 different Unique ID for Territory D00060 and 10 different Unique ID for Territory D00061.

Here I read my csv file in pandas like

csv_file = 'cust_valid.csv '
df=pd.read_csv( csv_file,delimi ter="|")

Filtered having customers <= 50

low_dense = df['NoOfCustomer'] <=50

And then iterted low_dense like
This part will only iterate the filterd zip_codes

for index,row in Highly_low.iter rows():
for loop in row:
print('S')

Here I wanna a write to another CSV file with columns like

Territory NoOfCustomers UniqueId
D00060 10 0001ASDDF900f
D00060 10 qwdfeed0909jkl
D00060 10 lhjkhj90090kllk m
D00060 10 jhjkhjk0909090
