scipy - One variable solver module in Python -


i'm writing code solve root in non-linear, 1 variable equation. root has in range of 0 1. code have far works floats have less 5 decimal places, wondering if knows of more precise solver module or function. (i've tried scipy.optimize.brentq, can't figure out how use it.)

from sympy import symbol, solve def find_intersection(a, ev):     x = symbol('x')     y = symbol('y')     y = (-(0.18*x + 5.87 - a)/(0.02*x-0.42))     temp_x = solve(1.35-x+1.4*y-0.33*x*y-(0.758-0.28*x)*(y)*(1-y)-(0.101+0.109*y)*(x)*(1-x)-ev, x)     value in temp_x:         if value>=0 , value<=1:             perm_x=value     return perm_x

sequelize.js - Sequelize: sort by enum cases -

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
