Hi all,

I am new to python, just was looking for logic to understand to write code in the below scenario.

I am having a file (filea) with multiple columns, and another file(fileb) with again multiple columns, but say i want to use column2 of fileb as a search expression to search for similar value in column3 of filea. and print it with value of rows of filea.

filea:
a 1 ab
b 2 bc
d 3 de
e 4 ef
.
.
.

fileb
z ab 24
y bc 85
x ef 123
w de 33 

Regards../ omps
