Check if an element exists in a list in Python by leveraging various efficient methods, each suited to different scenarios and requirements. This article will guide you through the multitude of ways to determine the presence of an element within a list, ranging from the straightforward in operator...
Note: Thecmp()method is supported in Python 2. # Python program to check if two lists of# tuples are identical or not# Initializing and printing list of tuplestupList1=[(10,4), (2,5)] tupList2=[(10,4), (2,5)]print("The elements of tuple list 1 : "+str(tupList1))print(...
iflen(my_list)==0:print("List is empty") Although the first approach is considered to be morePythonic, some people prefer the explicit second approach. Note that the officialPEP 8 Python Style Guiderecommends the first way: "For sequences, (strings, lists, tuples), use the fact that em...
It returnsTrueif “sub” string is part of “str”, otherwise it returnsFalse. Let’s look at some examples of usinginoperator in Python. str1='I love Python Programming'str2='Python'str3='Java'print(f'"{str1}" contains "{str2}" ={str2instr1}')print(f'"{str1}" contains "{s...
Python Code: # Define a function 'checkSubset' that checks if all elements of 'input_list2' are contained in 'input_list1'defcheckSubset(input_list1,input_list2):returnall(map(input_list1.__contains__,input_list2))# Create two lists 'list1' and 'list2'list1=[[1,3],[5,7],[...
The output confirms that indices0,1, and2are in range, while indices3and4are not in the range of the list. Check if Index Exists in Python List Usingtry-exceptBlock Using atry-exceptblock is a robust approach to handle potentialIndexErrorexceptions when checking if an index exists in a ...
Here, we have a list and a tuple and we need to check if there exists any one element which is common in both list and tuple in Python.
Check if a list has duplicate elements using the counter() method Conclusion Check if a list has duplicate Elements using Sets We know that sets in Python contain only unique elements. We can use this property of sets to check if a list has duplicate elements or not. ...
The any() function checks if any of these Boolean values is True. If so, it returns True otherwise it returns False. Open Compiler def is_substring_present_any(substring, string_list): return any(substring in string for string in string_list) res = is_substring_present_any("Tutorialsp...
If no common characters are found, the functions return True. Open Compiler def are_disjoint(strings): return all(not set(strings[i]).intersection(*map(set, strings[:i] + strings[i+1:])) for i in range(len(strings))) my_strings = ["hello", "world", "python"] if are_disjoint...
