Python Built-in Functions The Python built-in functions are defined as the functions whose functionality is pre-defined in Python. The python interpreter has several functions that are always present for use.
abs() The python abs() function is used to return the absolute value of a number. It takes only one argument, a number whose absolute value is to be returned. The argument can be an integer and floating-point number. If the argument is a complex number, then, abs() returns its magnitude....
Python Functions
Functions Functions are blocks of code that does something more complex in order to avoid repeating the same logic, or most of the same logic in our code. As the program grows, function makes the program more organized.
There are mainly two types of functions.
User-define functions - The user-defined functions are those define by the user to perform the specific task. Built-in functions - The built-in functions are those functions that are pre-defined in Python....
Python Operators
Operators Arithmetic Operators Comparison Operators Assignment Operators Logical Operators Bitwise Operators Membership Operators Identity Operators Arithmetic Operators Comparison Operators Assignment Operators Bitwise Operators Example:
if a = 7 b = 6 then, binary (a) = 0111 binary (b) = 0110 hence, a & b = 0011 a | b = 0111 a ^ b = 0100 ~ a = 1000 Logical Operators Membership Operators Identity Operators Operators Precedence
Python Data Types
Data Types Variables can hold values, and every value has a data-type. Python is a dynamically typed language; hence we do not need to define the type of the variable while declaring it. The interpreter implicitly binds the value with its type.
1. Numbers
2. Sequence Type
3. Dictionary
4. Set
5. Boolean
Checking type of data type Python enables us to check the type of the variable used in the program....
Python Variables
Variables Variables are storage locations that are used to store information that can later be referenced and manipulated. You can consider a variable as a sort of a container where you store an information that can later be accessed with the variable name.
1. Assigning Values to Variables In Python, variables are created when they are first assigned values. Values are assigned using the assignment operator (=).
name = "Packing box" # A string height = 10 # An integer assignment width = 20....
Python Fundamentals
Python interpreter To run Python programs, you will need the Python interpreter and possibly a graphical editor. A Python interpreter executes Python code (sometimes called programs).
Comments Using the hash-mark sign (#) # This is a comment. # This is a comment. # This is a comment. Using the three double quotes """ This is a multiline command This is a multiline command This is a multiline command """ Run Python We can start a Python program with the terminal or command line....
