When and Why to Use
Use these to save and retrieve values for use in survey logic or reporting.
• store_value() lets you assign a value (like a derived age or score) to a named variable
• get_value() retrieves that value later in the survey for use in branching, filtering, or display
Common use cases include:
• Calculating age from birth year
• Storing a derived score
store_value(name, value, **topics)
Parameter | Type | Required | Description |
name | str | yes | Name to assign to the stored value |
value | str or int | yes | Value to store, often calculated from a previous answer |
**topics | dict | no | Used for grouping and metadata in reporting |
get_value(name)
Parameter | Type | Required | Description |
name | str | yes | Name of the value to retrieve |
Returns: The stored value (any type)
Example Code
from datetime import datetime from survey import Survey s = Survey(**globals()) birth_year = s.numeric_question("What year were you born in?", min_max=(1920, 2020)) s.store_value("age", datetime.now().year - birth_year) s.terminate_if( s.get_value("age") < 18, "Sorry, this survey is for adults 18 and older." )Notes
• store_value can be used multiple times to keep track of intermediate calculations
• Values can be used in logic, shown in text, or passed to external APIs
• You can apply topics for each stored value to categorize them in your reporting schema
