Using the assignment operator with tuple unpacking is like a shortcut in Python. It helps you quickly swap values between variables or elements in a list, making your code shorter and easier to understand. Instead of using a temporary variable, you can directly switch values in just one line...
# Python program to swap element of a list # Getting list from user myList = [] length = int(input("Enter number of elements: ")) for i in range(0, length): val = int(input()) myList.append(val) print("Enter values to be swapped ") value1 = int(input("value 1: ")) ...
Again, the number of elements in the tuple on the left of the assignment must equal the number on the right. Otherwise, you get an error. Tuple assignment allows for a curious bit of idiomatic Python. Sometimes, when programming, you have two variables whose values you need to swap. In ...
