os.environ does not contain HOST variable

it helps some times This means that you've got a variable called HOST defined in your shell, but have not exported it.
Try this:
export HOST

Python 2.6 : How to pass variable to mysql query if it must be placed above application(environ?

seems to work fine Ok, this is sort of an answer to your earlier (deleted) question so a bit of "cheating", but you're asking the same thing I already answered there;
Your code was something like this pseudo code;
connection = mysql_connect()

def application(environ, start_response):
    <do some work>
def application(environ, start_response):   
    connection = mysql_connect()
    <do some work>

Is there a way in Python to check whether an entry to os.environ is a variable or a shell function?

I hope this helps . This feature is bash-specific, so a test for an exported shell function needs to do what Bash does. Experimentation and source code show that Bash recognizes an environment variable as a shell function at startup by the presence of a () { prefix in its value — if the prefix is missing, or even slightly altered, the variable is treated as an ordinary data variable.
Therefore, the equivalent Python check would look like this:
def is_env_shell_func(name):
    return os.environ[name].startswith('() {')

Why the contents of environ in the /proc file system differs from what extern environ pointed to?

Does that help The /proc/$pid/environ data shows the state of the env vars when the process started. If the environment vars were subsequently modified (e.g., via putenv()) that will be reflected in the return value of getenv() but not /proc/$pid/environ. You can see this in action by compiling and running the following program in one terminal and looking at its proc/.../environ in another terminal.
#include <stdio.h>
#include <stdlib.h>

int main() {
    char *home = getenv("HOME");
    printf("pid %d  HOME=%s\n", getpid(), home);

Any of those help , The problem is that the following line
sfdc_password = boto3.client('kms').decrypt(CiphertextBlob=b64decode(os.environ["L_PASSWORD"]))['Plaintext']
try :
    sf = Salesforce(username=sfdc_username,
    print('salesforce login good')
