如何将随机生成的python数学方程式发送到Chrome

Question

The code I am using:

import operator
import math
import random
from random import randint
from selenium import webdriver

vari1 = (random.randint(-99999999,999999))
vari2 = (random.randint(-99999999,999999))


ops = {'+':operator.add,
       '-':operator.sub,
       '*':operator.mul,
       '/':operator.truediv}

op = random.choice(list(ops.keys()))
answer = ops.get(op)(vari1,vari2)
print('{} {} {}?\n'.format(vari1, op, vari2))


browser = webdriver.Chrome()
browser.get("https://www.google.com/")
search = browser.find_element_by_name('q')
search.send_keys(answer)

What this does: Chooses 2 numbers between -99999999 and 999999 along with a random operator. It then proceeds to print it the complete equation in the cmd window. After it does that it opens up Chrome and goes to Google. It then types the answer of the equation (which was printed in the cmd window)

What I want: I want the equation to be inputted into the Chrome window. I don't want the answer but the equation

Answer 1

Pre-format your equation and send it with a newline at the end:

equation = '{} {} {} = \n'.format(vari1, op, vari2) 
search.send_keys(equation)

Works for me, I get this:
