So far I am able to read my parameter file but not able to store values into variables can anyone help me with this

What have you written to try and "store values into a variables"? What would you want the result of executing your program to be? — Scott Hunter, Mar 30 '19 at 22:48
@Scott Hunter my program should should store the values of DBHOSTNAME,DBSID,BEUSERNAME,BEUSERPASSWORD&HOSTPATHBE — Fahad, Mar 30 '19 at 22:51

If your file is consistent, this will store your info in a dictionary:

with open('envparam.config') as f:
    data = {}
    for line in f:
        key, value = line.strip().split('=')
        data[key] = value

You can then access it like this:

>>> data['DBSID']
SID

yes this code works now i want to save these values in a varible for exmple if i print DBSID it should shows the value of DBSID – Fahad Mar 30 '19 at 23:13
They are already stored in the dictionary. Try `print(data['DBSID'])` – Merig Mar 30 '19 at 23:16

You have to print outside the loop, when all the entries have been processed – Merig Mar 31 '19 at 09:34

To create a list with a line as each element, use the .split() method with "\n"(the newline character)

file = open('envparam.config').split('\n')
