So i want to create a variable number of environment variables, where servnuber is the number of environment variables i want and which is provided as an environment variable itself.

servnumber=os.environ['SERV_NUMBER']
vartest='host'
envtest='MY_HOST'
for x in range(1, servnumber):
    vartest+str(x)=os.environ[envtest+str(x)]

My desired result would be, if servnumber is 3, to create

host1=os.environ['MY_HOST1']
host2=os.environ['MY_HOST2']
host3=os.environ['MY_HOST3']

But I'm getting:

File "variableservers.py", line 49
    vartest+str(x)=os.environ[envtest+str(x)]
    ^ 
SyntaxError: can't assign to operator

Does this answer your question? [How do I create variable variables?](https://stackoverflow.com/questions/1373164/how-do-i-create-variable-variables) TL;DR don't do that... Use a list instead... – Tomerikoo Dec 03 '20 at 13:06
You mean saving the variables in a list instead of host1, host2, etc? – Mike Dec 03 '20 at 13:09
Well I can't write a comment as simply YES – Tomerikoo Dec 03 '20 at 13:10
I should change all the code but it might work, let me give a try – Mike Dec 03 '20 at 13:11
