sqlite3 - Retrieve value from a fetchone() call in python 3 -

-

i new python , can not find answer question anywhere. unless don't understand answers given. have database cursor , execute command:

cmd = 'select value measurement measurement_location ?' crs.execute(cmd, [location_id]) print(crs.fetchone())

which prints:

{'value': 73.97486139568466}

i need use float 73.97.... in calculations compute average. problem can't figure out how pull float fetchone() return.

fetchone returning dictionary each row mapping field name in result (only value in example) value row. use can do

cmd = 'select value measurement measurement_location ?' crs.execute(cmd, [location_id]) row = crs.fetchone() print(row['value'])  print(row['value'] * 100)

or whatever other things want result
