chosen_no = int(input('Please enter the Course Number '))

/当我打印上面的语句时，我得到了输入框，上面写着输入课程编号。

/在我输入后，它不会重定向，我不知道任何代码帮助都会被感谢。

Answer 1

您可以使用下面的代码获取基于索引的“href”。

lt = [{'number':1,'title':'Accounting and Finance :','href':'/courses/course-v1:IIMB+EEP_AC104x+EEP_AC104x/course/'},
        {'number': 2, 'title': 'Strategic Management :',
         'href': '/courses/course-v1:IIMBx+ST101x+082019EEP/course/'},
        {'number': 3, 'title': 'IIMBx Awards :',
         'href': '/courses/course-v1:IIMBx+Awards101+2019_T3/course/ '}
        ]
chosen_no = int(input('Please enter the Course Number '))

print ([x for i,x in enumerate(lt) if lt[i]['number']==chosen_no][0]['href'])

结果：

Please enter the Course Number 1
/courses/course-v1:IIMB+EEP_AC104x+EEP_AC104x/course/

Answer 2

chosen_no = int(input('Please enter the Course Number you want to Extract: '))
selectedCourse = 0
i = 0
for course in  coursesDict:
    if course['number'] == chosen_no:
        selectedCourse = course

    i = i+1

print(selectedCourse)
driver.get('https://your_site_url' + selectedCourse['href'])
