Python Readiness Series: Python Skills Self-Assessment

This assessment will help determine what additional practice you could benefit from as you continue your Python learning path. This is an anonymous, self-reported assessment and it is in your best interest to answer honestly and without looking up answers. If you aren't sure of an answer, you may select //I don't know//. This assessment is not a measure of intelligence or skill, but rather is a method for identifying gaps in your pre-existing knowledge and to offer recommendations for practice. At the end of this assessment, you will be provided with recommended practice lessons. ''Important:'' You will not be able to save your progress and return to this assessment later. Please allot yourself at least 30 minutes to complete this self-assessment.
