In the same way, inPython programming, variables are like those labels. Here, we can say that the memory space is like an empty shelf. There you can store different types of values (items) like numbers, decimals, letters, and sentences. However, to store that data, we need to use var...

Variables in Python Data Types in Python Operators Input and Output in Python Comments in Python 3. Python Strings Anything written in single or double quotes is treated as a string in Python. Strings are also immutable, which means that they cannot be changed once they are created. In Python...
If the packed objects are assigned to a tuple of names, then the individual objects are unpacked as shown in the diagram below, where you use a tuple of s* variables: Tuple Unpacking Here’s how this unpacking works in Python code: Python >>> s1, s2, s3, s4 = t >>> s1 'foo...
