This is why the most reliable way to check if an object is iterable is to pass the object to theiter()built-in function. Theiter()function raises aTypeErrorif the passed-in value doesn't support the__iter__()method or the sequence protocol (the__getitem__()method). ...
Check if Variable is a List withtype() The built-intype()function can be used to return the data type of an object. Let's create a Dictionary, Tuple and List and use thetype()function to check if a variable is alistor not:

In this article, you will learn different ways to check if an object is iterable in Python. 1. Using theiter()function Theiter()function takes an object as an argument and returns an iterator object if the object is iterable. Under the hood, theiter()function checks if the object has__...

An important part when dealing with an iterable object, in this case a list, is checking if there's anything to iterate through. If not handled properly, this can lead to a lot of unwanted errors. Python provides various ways to check if our list is empty or not, some implicit and ...
The __contains__ () in Python is an object method that checks whether a string object contains the specified string or not. Depending on the search result, it returns a Boolean value, True or False. Example: # Python program to check if a string contains the substring# Using __contains...
Learn how to check if a Python list contains a specific element with easy examples. Master list manipulation and element searching efficiently.
Python any(value is item or value == item for item in collection) The generator expression wrapped in the call to any() builds a list of the Boolean values that result from checking if the target value has the same identity or is equal to the current item in collection. The call to...
