我尝试了以下方法，但没有解决。

import numpy as np
weather = np.linspace(-5, 5, 3)
df_final = pd.DataFrame([], index=weather)
for ctr1 in weather:
    X1 = round(ctr1,1)
    for ctr2 in weather:
        X2 = round(ctr2,1)

        Y1 = regressor[0] * X1**3 + \
        regressor[1] * X1**2 + \
        regressor[2] * X1 + \
        regressor[3] 

        Y2 = regressor[0] * X2**3 + \
        regressor[1] * X2**2 + \
        regressor[2] * X2 + \
        regressor[3]

       slope = (Y2-Y1)/(X2-X1)

       df_final.loc[X1, X2] = np.NaN if X1 == X2 else slope

Answer 1

有几种方法可以选择该选项：

1)
element(by.cssContainingText('select[formcontrolname="brandName"] > option', 'APPLE')).click();

2)  
element(by.css('select[formcontrolname="brandName"] > option[ng-reflect-value="APPLE"]')).click();

3)
element(by.xpath('//select[@formcontrolname="brandName"]/option[text()="APPLE"]')).click();
