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 ...

Write a Python program to use the filter() function to remove empty tuples from a list. Write a Python program to implement a function that checks each tuple in a list and discards any that evaluate as empty.Python Code Editor:Previous: Write a Python program to replace last value of tup...
Note that the official PEP 8 Python Style Guide recommends the first way:"For sequences, (strings, lists, tuples), use the fact that empty sequences are false" # Correct: if not seq: if seq: # Wrong: if len(seq): if not len(seq): ...
This is the main difference between Python lists and tuples Iterability - which means we can iterate through it (go through all elements in the list in-order) The main attribute that will be focusing on is Iterability. An important part when dealing with an iterable object, in this case ...
