00:00https://realpython.com/lessons/python-string-contains-substring-summary/#t=0.64
And that’s a wrap.https://realpython.com/lessons/python-string-contains-substring-summary/#t=0.64
You’re at the end of How to Check if a Python String Contains a Substring.https://realpython.com/lessons/python-string-contains-substring-summary/#t=1.58
And you’ve learned quite a lot in this course.https://realpython.com/lessons/python-string-contains-substring-summary/#t=5.52
00:08https://realpython.com/lessons/python-string-contains-substring-summary/#t=8.94
Now you do have the skills to figure out whether there is actually the wordhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=8.94
"secret" in this long text,https://realpython.com/lessons/python-string-contains-substring-summary/#t=12.44
and you can download the slides for this course in the supporting materials andhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=14.42
then actually copy/paste this text.https://realpython.com/lessons/python-string-contains-substring-summary/#t=18.28
00:20https://realpython.com/lessons/python-string-contains-substring-summary/#t=20.17
So this is a little task that I want to send you off with.https://realpython.com/lessons/python-string-contains-substring-summary/#t=20.17
Take this long text and then apply the different ways that you learned to identifyhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=23.35
a substring in a text and figure out whether the word "secret" appears in here.https://realpython.com/lessons/python-string-contains-substring-summary/#t=28.04
00:34https://realpython.com/lessons/python-string-contains-substring-summary/#t=34.38
And these are the topics that you covered in this course. First,https://realpython.com/lessons/python-string-contains-substring-summary/#t=34.38
you learned how to confirm the presence of a substringhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=37.57
and that the best way to do this in Python is using the in operator.https://realpython.com/lessons/python-string-contains-substring-summary/#t=39.61
00:43https://realpython.com/lessons/python-string-contains-substring-summary/#t=43.6
Then you learned how you can generalize that check by removing the casehttps://realpython.com/lessons/python-string-contains-substring-summary/#t=43.6
sensitivity, and you did that by lowercasing,https://realpython.com/lessons/python-string-contains-substring-summary/#t=46.89
the string that you’re searching in. Next,https://realpython.com/lessons/python-string-contains-substring-summary/#t=49.57
you’ve worked with a couple of string methods that you can use to learn morehttps://realpython.com/lessons/python-string-contains-substring-summary/#t=52.13
about the substring,https://realpython.com/lessons/python-string-contains-substring-summary/#t=55.33
such as using .count() to figure out how often does it appear in the texthttps://realpython.com/lessons/python-string-contains-substring-summary/#t=56.28
or using .index() to figure out the location of the substring.https://realpython.com/lessons/python-string-contains-substring-summary/#t=60.94
01:06https://realpython.com/lessons/python-string-contains-substring-summary/#t=66.79
And that led us over to a situation where maybe you want to work more with thehttps://realpython.com/lessons/python-string-contains-substring-summary/#t=66.79
substring or you want to apply some conditions to the search.https://realpython.com/lessons/python-string-contains-substring-summary/#t=71.13
And both of that works well when you’re using regular expressions with the rehttps://realpython.com/lessons/python-string-contains-substring-summary/#t=74.31
module. And you’ve seen a couple of examples of how to do that. And finally,https://realpython.com/lessons/python-string-contains-substring-summary/#t=79.09
you also learned how you can confirm the presence of a substring inside of ahttps://realpython.com/lessons/python-string-contains-substring-summary/#t=83.69
pandas DataFrame column and look at the pandas way of doing that by usinghttps://realpython.com/lessons/python-string-contains-substring-summary/#t=88.25
.str.contains(). That’s all for this course.https://realpython.com/lessons/python-string-contains-substring-summary/#t=93.29
01:37https://realpython.com/lessons/python-string-contains-substring-summary/#t=97.8
There’s a couple of resources that I already shared,https://realpython.com/lessons/python-string-contains-substring-summary/#t=97.8
and here’s some other articles and courses where you can continue your learning.https://realpython.com/lessons/python-string-contains-substring-summary/#t=100.0
So the first one is called Strings and Character Data in Python.https://realpython.com/lessons/python-string-contains-substring-summary/#t=104.29
01:47https://realpython.com/lessons/python-string-contains-substring-summary/#t=107.31
That exists as a tutorial as well as a course,https://realpython.com/lessons/python-string-contains-substring-summary/#t=107.31
if you want to learn more about strings in general.https://realpython.com/lessons/python-string-contains-substring-summary/#t=110.21
Then we have all the resources on regular expressions and building regexes inhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=112.47
Python. There’s a tutorial and a video course as well.https://realpython.com/lessons/python-string-contains-substring-summary/#t=116.32
01:59https://realpython.com/lessons/python-string-contains-substring-summary/#t=119.58
And then there’s also a bunch of resources about pandas.https://realpython.com/lessons/python-string-contains-substring-summary/#t=119.58
And here I wanted to highlight the article on the pandas DataFrame that alsohttps://realpython.com/lessons/python-string-contains-substring-summary/#t=122.64
exists both as a tutorial and the course.https://realpython.com/lessons/python-string-contains-substring-summary/#t=126.96
02:09https://realpython.com/lessons/python-string-contains-substring-summary/#t=129.91
So these are three directions that you can continue your learning onwards fromhttps://realpython.com/lessons/python-string-contains-substring-summary/#t=129.91
here. And I hope you had fun and thanks for watching.https://realpython.com/lessons/python-string-contains-substring-summary/#t=134.34
