I want to read from Properties file and put that value in a string based on a key from file

I am new learning python and I have to deal with the properties file in that file the value will be present in key value pair and some how I think managed to readFile but not able to store or print the value based on a key.

I have tried with the jproperties libraries installed through pip.I have read the values in the object but unable to fetch the records from it. Have gone through https://pypi.org/project/jproperties/#parsing-a-property-file website for reference

from jproperties import Properties

class PropertiesReader:
    p = Properties()
    with open("foobar.properties", "rt") as f:
        p.load(f, "utf-8")

    s = p.__getitem__("name","value")
    z = p.__getattribute__("email","mail")
    print(s)
    print(z)

and the properties file

foobar.properties
    name = Harsh
    email = abc.xyz

and the output is 

Traceback (most recent call last):
  File "/home/harshk/PycharmProjects/demoPythonPOC/scratch.py", line 4, in <module>
    class PropertiesReader:
  File "/home/harshk/PycharmProjects/demoPythonPOC/scratch.py", line 7, in PropertiesReader
    p.load(f, "utf-8")
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 804, in load
    self._parse()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 731, in _parse
    while self._parse_logical_line():
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 686, in _parse_logical_line
    self._skip_whitespace()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 438, in _skip_whitespace
    c = self._peek()
  File "/usr/local/lib/python3.7/site-packages/jproperties.py", line 378, in _peek
    c = self._source_file.read(1)
  File "/usr/local/lib/python3.7/codecs.py", line 500, in read
    data = self.bytebuffer + newdata
TypeError: can't concat str to bytes

Process finished with exit code 1

I want to print like 

Harsh
abc.xyz

Test below code : https://repl.it/repls/EmptyRowdyCategories

from jproperties import Properties

p = Properties()
with open("foobar.properties", "rb") as f:
    p.load(f, "utf-8")


print(p["name"].data)
print(p["email"].data)

You're opening the file as if it's a text file:

with open("foobar.properties", "rt") as f:
    p.load(f, "utf-8")

But the jproperties docs shows that you need to open the file in binary mode:

with open("foobar.properties", "rb") as f:
    p.load(f, "utf-8")
