I'm learning python so I have two files with a lot of lines:

file 1

71528
1452
14587

file 2

country_hoj_17458   9  CA   5    CA 78.4
country_hoj_1452   10  CA   15   CA 96.5
country_hoj_14787  19  CA   51   CA 12.4
country_hoj_15742  19  CA   51   CA 12.4
country_hoj_171528  19  CA   51   CA 12.4

I want print the lines where the pattern (number) file 1 matchs with the file 2 in the first column. I want an outfile like this

 country_hoj_1452   10  CA   15   CA 96.5country_hoj_14787  19  CA   51   CA 12.4

my script is like that:

filename = numbers.txt
filename2 = data.txt
with open(filename) as f:with open (filename2) as m:for line in f:if line in m:print (m)

What I need to fix in it? Anybody can help me and support me? Thanks a lot

filename = 'numbers.txt'
filename2 = 'data.txt'with open(filename) as numberLines:with open (filename2) as dataLines:nL = numberLines.read().splitlines()dL = dataLines.read().splitlines()dataReadLines = [j for i in nL for j in dL if i in j]#dataReadLines = [i for i in nL]print (str(dataReadLines))

Another answer where each key is paired with their respective data find. I've changed your inputs and you can easily understand using the below code.

from collections import defaultdictfilename = 'numbers.txt'
filename2 = 'data.txt'with open(filename) as numberLines:with open (filename2) as dataLines:nL = numberLines.read().splitlines()dL = dataLines.read().splitlines()defDList = defaultdict(list)dataReadLines = [defDList[i].append(j) for i in nL for j in dL if i in j]#dataReadLines = [i for i in nL]print (defDList)
