Robot Framework Parameterizing using yaml file

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.
