Topics beyond the basics of Python.
Conditional statements in Python
Handled with 'if' keyword.
variable = value if the conditional is met otherwise set to this value
If you have two environments, development and production:
dev = "dev"
prod = "prod"
script_arg = "dev"
if script_arg == prod:
db_env = prod
else:
db_env = dev
db_env = prod if script_arg == prod else dev
Example with True/False:
script_arg = True
db_env = prod if script_arg == True else dev
Example with testing the existence of something:
script_arg = None
db_env = prod if script_arg else dev
Useful for config files and also different switches and options for a script.
Should be used for relatively simple expressions so the line is still readable.
