How can I check an environment variable within a robot?

I have a line:

${http_proxy}=  Remove String  %{HTTP_PROXY}  http://

In my test.txt for robot framework

I would like this suggestion to do well if the HTTP_PROXY environment variable exists. So far, if HTTP_PROXY doesn't exist, it fails like this:

"Environment variable 'HTTP_PROXY' does not exist"

yes and another solution: $ {http_proxy} = Get environment variable HTTP_PROXY $ {EMPTY}



where $ {EMPTY} is a custom variable for the default value

One solution is to use Evaluate to get the value of an environment variable using a method get

in a dictionary os.environ

that allows you to specify a default value:

| | ${HTTP_PROXY}= | Evaluate os.environ.get("HTTP_PROXY", "")


The above will set ${HTTP_PROXY}

to an empty string if the environment variable doesn't exist.
