how can I generate a password in hashlib

[go127a]

Hi
i have a csv file, it contain name and password. I am going to readout and write the password in a csv file.

import csv
import itertools
from collections import OrderedDict
import hashlib

with open ('code.csv', 'r') as input_file_name:
    reader=csv.reader(input_file_name)
    key=[]
    val1=[]
    for row in reader:
        name = row[0]
        val=[str(num) for num in row[1:]]
        key.append(name)
        val1.append(val)
        value = list(itertools.chain.from_iterable(val1)) #making a simple list from list of list in value
        value=[str(i) for i in value]
    print(key)
    dictionary = dict(zip(key, value))
print(dictionary)

my problem is, how can I generate password from the value in dictionary.
in the other words reach the password, I know the pass can be varied between 1000 to 9999.

sample input csv file:

peter,99b057c8e3461b97f8d6c461338cf664bc84706b9cc2812daaebf210ea1b9974
adam,85432a9890aa5071733459b423ab2aff9f085f56ddfdb26c8fae0c2a04dce84c

and the correct output:

peter,5104
adam,9770
