This will include all the information About Python - Basics; This includes the basic syntax, variables, data types, conditionals, typecasting, exceptions, functions, lists, tuples, sets and dictionaries.

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Vocabulary

String
a list of characters such as numbers, letters, symbols
Variable
holds a value and can be changed
Input

displays inform­­ation on the screen
value
the number or string can be store in valuable
Syntax Error
make impossible to the phase
loop
the condition used in python
operator

displays inform­­ation on the screen
input()
receives inform­­ation from the user
int()
converts a value to an integer
float()
converts a value to a decimal number
str()
converts a value to a string

TypeCa­sting

int()
x = int(1)
1
float()
y = float(2.8)
2.8
str()
z = str("3v­")
3v

variables

Hello World
print(­"­Hello world!­")
Hello World with a Variable
 
msg = "­Hello World!­"
print (msg)
Concat­enation (combining strings)
 
name = 'albert'
lname = 'einstein'
Full = name + ' ' + lname
print(­Full)
Variables are used to store values. A string is a series of
charac­ters, surrounded by single or double quotes.
