Basic Foundation Concepts - Project 3
In this program the basic python such as comments , varibles, Data Types, Booleans and operations are explained with examples.
The int() function converts the specified value into an integer number.
int(value, base) -syntex
Creating Variables : Variables are containers for storing data values.Unlike other programming languages, Python has no command for declaring a variable.A variable is created the moment you first assign a value to it.
String Literals
String literals in python are surrounded by either single quotation marks, or double quotation marks.
‘hello’ is the same as “hello”.
You can display a string literal with the print() function:
example :
print(‘in 2020, you will be’, 2020 -int3)
counter = 100
miles = 1000.0
name = “john”
Built-in Data Types In programming, data type is an important concept.Variables can store data of different types, and different types can do different things.Python has the following data types built-in by default, in these categories:
Text Type: | str |
Numeric Types: | int, float, complex |
Sequence Types: | list, tuple, range |
Mapping Type: | dict |
Set Types: | set, frozenset |
Boolean Type: | bool |
Binary Types: | bytes, bytearray, memoryview |
Python Arithmetic Operators:
Operator | Name | Example |
+ | Addition | x + y |
– | Subtraction | x – y |
* | Multiplication | x * y |
/ | Division | x / y |
% | Modulus | x % y |
** | Exponentiation | x ** y |
// | Floor division | x // y |
