Python program to find String in a List - GeeksforGeeks

String found! The for loop iterates through the list and checks each element against the target string. While slower than the in operator, it gives us a greater control over the process. List comprehensions allow us to create a new list containing matching elements.

Help!: Check if a Python list item contains a string inside another string but with conditions
Here's two possibilities. If the way you get it done isn't important, you could use a regex because writing string parsing code is always sorta annoying. The regex [aeiou]*[f][aeiou]* would work I think. It matches any number of vowels, then a single "f", and then any number of vowels again. There's also another option. You have two conditions. It seems you want a single "f", which can be checked via word.count("f") == 1 and that every letter (excluding the "f") be a vowel. Essentially, every letter should pass letter == "f" or letter in "aeiou". To check every letter, you can utilize the built-in Python functionall(...). Checking that both these conditions hold, you should get the desired result. More on reddit.com

r/learnpython on Reddit: How to check if any element in a list contains a substring
October 28, 2019 -
Say I have a list of strings like: ["Hey dude", "Hey bro", "Sup dude", "Hey bud"]
How do I check if *any* of those strings in the list contain the word "Sup"?Alternatively, in my case, I could also check if *all* of the strings contain "Hey" , which I also don't know how to do.
(Sorry, I'm new to Python)
Edit: Thank you so much for all the help, guys <3

If you don't need to know exactly which element(s) contain the substring, then you could use the any built-in function in combination with a list comprehension l = ["Hey dude", "Hey bro", "Sup dude", "Hey bud"] substring = "Sup" if any([substring in element for element in l]): print(f"One or more elements of {l} contain the substring {substring}") else: print(f"No elements of {l} contain the substring {substring}") Here's an explanation about the any function. Alternatively, switch out any for all if you want to check if all the elements of the list contain the substring. all documentation

Sure. Here's how I might approach it. There may be shorter / clearer ways also. # define a var containing the universe of phrases list_of_phrases = ["Hey dude", "Hey bro", "Sup dude", "Hey bud"] # define var to be populated by phrases that match criteria later interesting_phrases = [] # process the list of phrases for phrase in list_of_phrases: if "dude" in phrase: # we're interested in phrases with the word "dude" in them interesting_phrases += [phrase] # this one is interesting, so add it to the list # check out the results print(interesting_phrases)

def myfun(str,list):
for a in list:
if not a in str:
return False
return True
return true must be outside the for loop, not just after the if statement, otherwise it will return true just after the first letter has been checked. this solves your code's problem :)

July 11, 2025 - Testing if string contains an element from list is checking whether any of the individual items in a list appear within a given string. any() is the most efficient way to check if any element from the list is present in the list.

To check for the presence of 'abc' in any string in the list:
xs = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
if any("abc" in s for s in xs):
...
To get all the items containing 'abc':
matching = [s for s in xs if "abc" in s]

Just throwing this out there: if you happen to need to match against more than one string, for example abc and def, you can combine two comprehensions as follows:
matchers = ['abc','def']
matching = [s for s in my_list if any(xs in s for xs in matchers)]
Output:
['abc-123', 'def-456', 'abc-456']

r/learnpython on Reddit: Help!: Check if a Python list item contains a string inside another string but with conditions
January 13, 2021 -
I have two days learning python but I really need to do that code. I also posted this question in StackOverflow but it got downvoted the first second.
I want to make a function to print all the words that contain a specific consonant (only one) and any amount of vowels, but I don't know how to introduce the conditions here.
I made a list with 4 elements via the input method (I know I use a different way), and a method that prints all the words that include the letter "f", but as I said, it needs to be more specific (only one consonant, "f" in this case, and any amount of vowels):
list = []
for x in range (4):
words = str(input("Type a word "))
list.append(words)
#This method kinda works, but it needs to be more specific.
matching = [s for s in list if "f" in s]
print(matching) In my code, if I have words with the letter "f", I'll get a list with all the words containing any amount of "f" letters and any other consonant, but I just want one consonant "f" and vowels, not the other consonants.
My desired result is like
list = [fox, alfa, fa, real, fou]
#['fa', 'fou']

How to Check if a Python String Contains a Substring – Real Python
September 10, 2025 - In this example, you use .split() to separate the text at whitespaces into strings, which Python packs into a list. Then you iterate over this list and use in on each of these strings to see whether it contains the substring "secret".

Use a generator together with any, which short-circuits on the first True:
if any(ext in url_string for ext in extensionsToCheck):
print(url_string)
EDIT: I see this answer has been accepted by OP. Though my solution may be "good enough" solution to his particular problem, and is a good general way to check if any strings in a list are found in another string, keep in mind that this is all that this solution does. It does not care WHERE the string is found e.g. in the ending of the string. If this is important, as is often the case with urls, you should look to the answer of @Wladimir Palant, or you risk getting false positives.

It'll work since we first convert all items to string first using str(). Unlike JavaScript, Python won't do the conversion for you. In this Byte, we've explored three different methods to check if a string contains any element from a list in Python.

How to Check if a Value is Included in a Python String or List
So this in operator is incredibly helpful because it checks not only for membership in strings so it not only tells you if one string is found inside of another string but it also can work with collections of data such as lists. So imagine that you perform a database query and you get back all these usernames and you want to check to see is one other person's username is it contained in that list of data? You can run your code just like this, you do not have to go and create your own loop and check the entire list and see if it matches up. You can just ask python is this included and the proper way to say it is, is it a member of this collection and it works very nicely.
