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}" )

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

We can use try and except to continue running code even if we
come across an error.

In python, you can use try, except and finally to catch errors to keep
running your code even when you run into an error.

finally:

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.')
