Different Types of Comments
Data types in Python
Introduction to Python comments
Sometimes, you want to document the code that you write. For example, you may want to note why a piece of code works. To do it, you use the comments.
Typically, you use comments to explain formulas, algorithms, and complex business logic.
When executing a program, the Python interpreter ignores the comments and only interprets the code.
Python provides three kinds of comments including block comment, inline comment, and documentation string.
single-line comment
A single-line comment begins with a hash (#) symbol and is useful in mentioning that the whole line should be considered as a comment until the end of the line.
Multi-line comment
Multi-line comment is useful when we need to comment on many lines. You can also use a single-line comment, but using a multi-line instead of single-line comment is easy to comment on multiple lines.
In Python Triple double quote (""") and single quote (''') are used for Multi-line commenting. It is used at the beginning and end of the block to comment on the entire block. Hence it is also called block comments.
Data types are an essential concept in the python programming language. In Python, every value has its own python data type. The classification of data items or to put the data value into some sort of data category is called Data Types. It helps to understand what kind of operations can be performed on a value.
Built-in Data Types in Python
Binary Types: memoryview, bytearray, bytes
Boolean Type: bool
Set Types: frozenset, set
Mapping Type: dict
Sequence Types: range, tuple, list
Numeric Types: complex, float, int
Text Type: str
