Robot Framework Parameterizing using yaml file - selenium-webdriver

Question

Hi can anybody help me parameterize the string word so it will fetch from my yaml. I tried to run however I'm getting an error it shows failed: Using YAML variable files requires PyYAML module to be installed. Typically you can install it by running pip install pyyaml. but I already install pyyaml on my local machine. your response is highly appreciated. Thank you so much
Expected Result: ${String} parameter should get the value from my robot.yaml (Ralph) value

In robot.yaml define PYTHONPATH like this:
PYTHONPATH:
- .
- string: "RALPH"
Make sure you have installed PyYAML, then include robot.yaml and collections library in the robot file:
Variables path_to_file/robot.yaml
Library Collections
After this you can extract string value inside the test like this:
${value} = pop from dictionary ${PYTHONPATH[1]} string
log to console ${value}
This will print:
RALPH
Second item in PYTHONPATH list is a dictionary, so you first need to access ${PYTHONPATH[1]} and then pop the needed key (in your case string) in order to return its value.
