The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects ...
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...
Method 2: NumPy array empty check-in Python using shape() function Theshape()method in the NumPy Python library returns a tuple in Python representing the dimensions of the array. An empty array will have a shape of(0,). We can use this method to check if a NumPy array is empty in ...

Q: Can these methods be used to check if other collections, like tuples or dictionaries, are empty? A: Yes, these methods can be used to check if any collection in Python, not just lists, is empty. An empty tuple, dictionary, set, etc., are all considered False in a boolean context...
Empty tuples and ranges produce a True result. In the last example, calling range() with 0 as an argument returns an empty range object, so all() gives you True as a result.You can also pass tuples containing expressions, Boolean expressions, or Python objects of any type to all(). ...
