I might be using wrong python terminology.

I have an array of 3 integer elements: month, date and year.
However, I am not able to print each individual element when concatenating strings.

import ssl
import OpenSSL
import time
import sys

def get_SSL_Expiry_Date(host, port):
 cert = ssl.get_server_certificate((host, 443))
 x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
 raw_date = x509.get_notAfter()
 decoded_date = raw_date.decode("utf-8")
 dexpires = time.strptime(decoded_date, "%Y%m%d%H%M%Sz")
 bes = dexpires.tm_mon,dexpires.tm_mday,dexpires.tm_year
 print (bes)
 #print(bes[0]+"/"+bes[1]+"/"+bes[2])

domain = sys.argv[1]
port = 443
get_SSL_Expiry_Date(domain, port)

If I uncomment line 14, I get an error:

TypeError: unsupported operand type(s) for +: 'int' and 'str'

I am trying to get the date in this format (all strings): Month/Date/Year.

What am I doing wrong?

Simply use:

print(time.strftime("%m/%d/%y",dexpires))

See also https://docs.python.org/3/library/time.html

In general python modules usually contain all kinds of reformatting functions you don't have to reinvent them.

Example:

>>> dexpires=time.strptime('20180823131455z','%Y%m%d%H%M%Sz')
>>> dexpires
time.struct_time(tm_year=2018, tm_mon=8, tm_mday=23, tm_hour=13, tm_min=14, tm_sec=55, tm_wday=3, tm_yday=235, tm_isdst=-1)
>>> time.strftime('%m/%d/%y',dexpires)
'08/23/18'
>>>

You can use Python's format() method to handle it (much cleaner also):

print("0/1/2".format(bes[0],bes[1],bes[2]))

_{...or further simplified (thanks Anton)}

print("0/1/2".format(*bes))

↳ Python String Formatting

First you have to convert int values to string than only you are able to concave them.
You can use str() inbuilt method

print(str(bes[0])+"/"+ str(bes[1])+"/"+ str(bes[2])) #convert int to str first.
