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, tags)

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
tags	s.tag()	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 tags for each stored value to categorize them in your reporting schema
