You need to write a regular expression in python as the judgment condition for the if Condition Statement. The keywords are "/course/"/specializations/"and"/learn, the structure is as follows:

If a line of link match/course /:

'''

Match a line of elif connections/specializations /:

'''

Match a line of else connections/learn /:

'''

I am a beginner in python. I have read a regular expression and I am not very familiar with it. Please write a regular expression that can be used as a matching condition for judgment. Then I can recommend some regular expression learning materials! Thx!

Just check if there is any in?

def check_url(word, url):    return word in urlfor u in urls:    if check_url('/course/', u):        do something    elif check_url('/specializations/', u):        do something    elif check_url('/learn/', u):        do something

import reraw = '''https://www.coursera.org/course/inforiskhttps://www.coursera.org/specializations/cloudcomputinghttps://www.coursera.org/learn/python-data'''check_func = lambda url, key: re.search('^https://www.coursera.org/%s/.+' % key, url)for url in raw.split('\n'):    if check_func(url, 'course'):        print 'I m course'    elif check_func(url, 'specializations'):        print 'I m specializations'    elif check_func(url, 'learn'):        print 'I m learn'

Regular expressions are used here..+, Where.Any character,+Represents more than one character,.+Is to match more than one arbitrary character.
In PythonreThe module is a regular expression-related module.re.searchIf the string is matched successfully, an object is returned. Otherwise, None is returned.
The re module also has other functions, suchre.findall,re.match,re.replaceAnd so on

You cannot directly use in. For example, if the url is https://www.coursera.org/course/specializations, both specializationsand coursecan be matched.
Hope to help you.
