Python 3.4 : Iterate through DataFrame column to match strings

I want to return edgar/data/915802/0001398344-15-001900.txt if 1398344 matches from a DataFrame column. (There will be multiple matching values)

I am currently trying the following code to return each line which matches the 10-digit starred number from the dataframe column stockStat.CIK.

import pandas as pd



stockStat = pd.DataFrame.from_csv(path ='/home/aranjohn/StockRec/stockData/csvData')

print(stockStat)

q1 = open('/home/aranjohn/StockRec/StockIndex/edgar.full-index.2015.QTR1.master.idx', 'r')

q2 = str.splitlines(q1.read())

strStockStat = str(stockStat.CIK)

for eachCik in strStockStat:
    for eachLine in q2:
        if eachCik in eachLine:
            print(eachCik, eachLine)

I understand the logical error here in which I end up returning every CIK number and every line. How would I only return eachLine that contains eachCik?
