• Different Kinds of Python Data Types

  • Numeric data types: int, float, complex.
  • String data types: str.
  • Sequence types: list, tuple, range.
  • Binary types: bytes, bytearray, memoryview.
  • Mapping data type: dict.
  • Boolean type: bool.
  • Set data types: set, frozenset.
• Python is commonly used for developing websites and software, task automation, data analysis, and data visualization
• A Python variable is a reserved memory location to store values
• • For Loop. A for loop in Python is used to iterate over a sequence (list, tuple, set, dictionary, and string). ...
  • While Loop. The while loop is used to execute a set of statements as long as a condition is true. ...
  • Nested Loop.
• To write a Python script, use an ordinary plain text file and add Python instructions.
• Input() Function. This built-in function reads user input from the keyboard and returns it as a string value.
• The print() function prints output on the screen. It can be called with one or more arguments separated by commas.
• .py - the extension that indicates it's a python program
• In Python, we define a function using the def keyword followed by the name of the function and its parameters inside parentheses.
• Python has four basic data types: numbers, strings, lists, and tuples.
• Functions allow us to group together related code into reusable blocks. They make our programs easier to read and understand.
• Lists are enclosed within square brackets []
• Strings are enclosed within single quotes ('') or double quotes ("")
• A variable is a container to hold values. In Python, variables are created when they are assigned a value.
• A binary number system is one of the four types of number system. In computer applications, where binary numbers are represented by only two symbols or digits, i.e. 0 (zero) and 1(one).
• Boolean expressions are the expressions that evaluate a condition and result in a Boolean value i.e true or false. Ex: (a>b && a> c) is a Boolean expression. It evaluates the condition by comparing if 'a' is greater than 'b' and also if 'a' is greater than 'c'.
• This little device has a lot of features, like 25 red lights that can flash messages. There are two unprogrammable buttons that can be used to control games. The BBC micro:bit can even detect motion and tell you which direction you're heading in.
