Python Find String in List: Methods and Examples | DigitalOcean
1 month ago - A common point of confusion is that in on a list checks for an exact match, when you may just want to know whether any element contains a target substring. The following patterns solve this and let you choose the result you need: the matching elements, a True/False answer, or just the first match. Use a list comprehension with the in operator (which does check for substrings inside individual strings) to collect every element that contains the target text:

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']
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)

February 2, 2024 - In the above code, list comprehension is used to search for strings having a in the list py_list. Note that writing the same code using other functions or loops would have taken more time, as more code is required for their implementation, but list comprehension solves that problem.

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']

July 23, 2025 - a = ['Learn', 'Python', 'With', 'GFG'] found = False for item in a: if item == 'Python': found = True break if found: print("String found!") else: print("String not found!") ... 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.

Copied!my_list = ['BOBBY', 'HADZ', 'COM'] substring = 'z' result = any(substring.lower() in word.lower() for word in my_list) print(result) # 👉️ True if any(substring.lower() in word.lower() for word in my_list): # 👇️ this runs print('The substring is contained in at least one of the list items') else: print('The substring is NOT contained in any of the list items') The str.lower method returns a copy of the string with all the cased characters converted to lowercase. The method doesn't change the original string, it returns a new string. Strings are immutable in Python.

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.
