"""
Some specific exceptions (Lengthy but time-saving )- 

ArithmeticError - Raised when an error occurs in numeric calculations

AssertionError	- Raised when an assert statement fails

AttributeError	- Raised when attribute reference or assignment fails

Exception - Base class for all exceptions

EOFError -	Raised when the input() method hits an "end of file" condition (EOF)

FloatingPointError -	Raised when a floating point calculation fails

GeneratorExit -	Raised when a generator is closed (with the close() method)

ImportError -	Raised when an imported module does not exist

IndentationError -	Raised when indendation is not correct

IndexError -	Raised when an index of a sequence does not exist

KeyError -	Raised when a key does not exist in a dictionary

KeyboardInterrupt -	Raised when the user presses Ctrl+c, Ctrl+z or Delete

LookupError -	Raised when errors raised cant be found

MemoryError -	Raised when a program runs out of memory

NameError -	Raised when a variable does not exist

NotImplementedError -	Raised when an abstract method requires an inherited class to override the method

OSError -	Raised when a system related operation causes an error

OverflowError -	Raised when the result of a numeric calculation is too large

ReferenceError -	Raised when a weak reference object does not exist

RuntimeError -	Raised when an error occurs that do not belong to any specific expections

StopIteration -	Raised when the next() method of an iterator has no further values

SyntaxError -	Raised when a syntax error occurs

TabError -	Raised when indentation consists of tabs or spaces

SystemError -	Raised when a system error occurs

SystemExit -	Raised when the sys.exit() function is called

TypeError -	Raised when two different types are combined

UnboundLocalError -	Raised when a local variable is referenced before assignment

UnicodeError -	Raised when a unicode problem occurs

UnicodeEncodeError -	Raised when a unicode encoding problem occurs

UnicodeDecodeError -	Raised when a unicode decoding problem occurs

UnicodeTranslateError -	Raised when a unicode translation problem occurs

ValueError -	Raised when there is a wrong value in a specified data type

try and except in python

# Try & Except :-

# Try     => Test The Code For Errors
# Except  => Handle The Errors

# The Try & Except ==> Complete Each Other
# You Can't Type One Without The Other

# Example, We Need From The User To Write His Age
# Age Mean Integer
# But What If He Type String
# Of Course We Show To Him Wrong Message

try : # I Will Try The Code

  # If The User Type His Age, Mean Integer
  age = int( input( "Write Your Age Please: " ) ) 
  
  # This Message Will Show To Him
  print( f"Your Age Is {age}" ) 

except : # If I Found Error, I Will Show To Him Wrong Message

  # But If He Type Something Else, This Message Will Show To Him
  print( "Wrong Value, Please Try Again" )

try and except in python

# Try and Except in python are for taking care of errors
# which may occur at runtime.
# For example:

# If flask is not installed, you will get an ImportError saying flask
# is not installed.
# The try keyword is to try running that block of code which may cause an error.
try:
    from flask import Flask
except ImportError:
    print('Flask is not installed! Use pip install flask to install it.')
