Study Notes

Integral data types include int, float, bool, and complex.
NoneType category includes the None data type, representing the absence of a value.
An immutable sequence of characters is represented by the str data type.
list and tuple belong to the collection data types in Python.
Data types in Python facilitate memory allocation by determining how much memory to allocate for different types of data.

Mutable and Immutable Types

The set data type is used for representing a mutable collection of unique elements.

Number Systems

The Binary Number System is base 2.
The Octal Number System contains 8 unique digits (0-7).
Binary Values in Python are stored in the form of integers prefixed with 0b or 0B.
Humans predominantly use the Decimal Number System (base 10) for everyday operations.
The Hexadecimal Number System has 16 digits (0-9 and A-F).
The number system understandable by operating systems and processors is the Binary Number System.

Python Code and Binary Values

Executing a = 0B1101011111 assigns the binary value to variable a, converting it to decimal.
For a = 0b1111 and b = 0B101, the operation a + b results in a decimal value of 16.
Assigning a = 0b10102 raises a SyntaxError due to the invalid binary digit '2'.
The prefix 0o or 0O indicates that the number is in the Octal Number System.

Octal Number System Details

The Octal Number System has 8 unique digits (0-7).
When binary data is stored, Python's execution environment handles it efficiently, allowing operation on data without manual conversions.

Purpose of Specific Data Types

The int data type in Python represents whole numbers and is used for performing arithmetic operations.
When a is assigned 10, executing print(id(a)) provides the unique memory address of the variable.
After c = a + b where a = 100 and b = 200, running print(c, type(c)) outputs 300 and <class 'int'>.
For a = 0o145; print(a, type(a)), the output will be the decimal conversion of octal 145 and its respective type.
Assigning a value of 0o8 raises a SyntaxError as '8' is not a valid octal digit.
Attempting to store 0O109 results in a SyntaxError due to '9' being invalid in octal.
In the expression a = 0O77, executing print(a, type(a)) will output 63 and its type.
Storing a value of 0o72 is valid, and it will convert to decimal correctly.
If a = 0O1001 is attempted, the value will be interpreted as octal, converted, and printed as a decimal number.
