Python Syntax:
==============
Identifier
==========
a = 10
a = 20
a = 30

print(a)

print(a+a+a)

a = 10
b = 20
c = 30

print(a+b+c)

==> Identifier is a name which it can use to identify elements in a program.
==> elements in a program: variable, function, method, class, object, module etc.
==> Identifier can be used to identify the python program elements uniquely.

Identifier Rules/Naming Conventions:
====================================
1) Identifier should always define with:
	alphabets, digits and underscore sign only.
Note: If an identifier with all digits ==> is invalid
2) Identifier should always start/begin with either alphabet or underscore only.

a = 123
a_123 = 231
a123 = 231
_123a_b = 120

print(a)
print(a_123)
print(a123)
print(100 == 100)
print(123 == 100)
print(_123a_b)

3) No keyword as an identifier.
4) Python identifier is case sensitive.

# def = 123
Def = 123.234
DEF = 123

# print(def)
print(Def)
print(DEF)


Types of Errors:
================
Error ==> can interrupt the program
	it can give immediate termination from the execution without result.
==> three types of errors:
	1) Syntax Errors/Programmer mistakes
	2) Run time errors/Exception

# script
# login success or fail

username = input("Enter Username:")
password = int(input("Enter password:"))

if username == 'Admin2024' and password == 2024:
    print("Login Success")
else:
    print("Login fail")

	3) Logical Errors
	==================

def depositAmount(amount,accountNumber):
    balance = 1234.00
    if accountNumber == "AC57360201000":
        balance = balance * amount # 11234.00
    print("My Balance = ",balance)
    
depositAmount(10000,"AC57360201000")
================================================

Variable
========
==> is a name/identifier
which can use to store values
==> variable is simply specified as "named memory".
==> can also specify as "container"
==> Python is dynamically typed language.

High level Programming languages:
=================================
==> categorized into three types:
	1) Statically typed
	===================
		==> based on the type of the variable
			the value assignment can be get rounded-off.
		Ex: C Language

	2) Strongly typed:
	==================
		==> based on the type of variable,
			the value assignment should be.
		Ex: Java

	3) Dynamically typed
	=====================
		==> For this type,
			no need to define the type of the data/variable at definition time.
		==> The python can automatically detect/read the type of the value for the variable, because python is dynamically typed.

a = 123
b = True
c = "Text"

print(type(a))
print(type(b))
print(type(c))
