小白请教问题，python3.6+selenium+chrome淘宝测试，报错<class 'Exception'>代码如下

browser = webdriver.Chrome()
wait = WebDriverWait(browser, 10)
def search():
    try:
        browser.get('https://www.')
        input = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "#q")))
        submit = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "#J_TSearchForm > div.search-button > button")))
        input.sendkeys('美食')
        submit.click()
    except Exception:
        print(Exception)


def main():
    search()


if __name__ == '__main__':
    main()

能打开浏览器但不能进行其他操作，报错为<class 'Exception'>，请教一下什么原因
