Question

我是python的新手，我第一次使用熊猫。我在http://pastebin.com/VxeUT5zW看到了一个帖子并试图实现这一点。我正在使用python 3.4并安装了所有必需的软件包。但我得到一些错误。我试图自己纠正它，检查互联网和所有..但我无法纠正它。请帮我纠正。

for single_price_value in data['price']:
    y_parameter.append(float(single_price_value))
return x_parameter, y_parameter

return predictions

# noinspection PyArgumentList
plt.plot(x_parameters, regr.predict(x_parameters), color='red', linewidth=4)
# Supress axis value
plt.xticks(())
plt.yticks(())
plt.show()


X, Y = get_data('C:\Python34\data\input_data.csv')
predicted_value = 700
result = linear_model_main(X, Y, predicted_value)
print('Constant Value: {0}'.format(result['intercept']))
print('Coefficient: {0}'.format(result['coefficient']))
print('Predicted Value: {0}'.format(result['predicted_value']))
show_linear_line(X, Y)

我得到的错误是：
