ERRORS
======

errors are a nightmare to every programmer.
Most of the time, the problem is a typo, followed closely by
a misunderstanding of indentation and standards.


Standards
---------
Standard is how organized your code is. With python,
unlike most languages, you define blocks of code like
functions by indentation. Most python editors will automatically
indent for you where it is necessary. With this, if you are ever
coding along and find python automatically indenting you where
you don't think it should, this should raise a flag for you to
figure out.


NameError
---------
There are some more in-depth common-issues that you'll
find from time to time.For now I will just
keep these ones basic.
The first error we'll discuss is the ``NameError:`` is not defined


As obvious as this might appear to you, this gets people amazingly. 
Just learn to recognize the``is not defined``
chances are you typoed the definition of the variable or when you
are referring to it. 

.. code-block:: python
        variable = 55
        print(varaible)
        
the ``print`` is correct but we have typoed a name ``variable``


Indentation error
-----------------
Another error that always get people is the indentation issues.
You will see ``expected an indented block`` as a
popup when you never enter an indented block for
something that requires it, like a function.


.. code-block:: python
        def task1():
        def task2():
            print('more tasks')

The two function are not separated as you can see.The should be an 
indentation of four spaces between the two functions ``def task1():``
and ``def task2():``



With that code you will get the ``unexpected indent`` error and you
can correct it using the following code.
.. code-block:: python
        def task1():
            print('task')
        def task2():
            print('more tasks')
            
The following code also gives you an error as well.Indentation can be
at times be very boring to correct.

.. code-block:: python
        def task():
            print ('stuff')
            
        print('more stuff')

            print('stuff')



EOL while scanning string literal
---------------------------------
This usually happens when you do not close off the backets and quotes.

.. code-block:: python
        def task():
            print('some people find themselves committing this too


            print('ouch...')
                  
                                    
The  best way to solve errors is to know the name of the error,
this makes it very easy to solve the error.The errors i have meontioned 
above are one of the most common errors, that you will face in your 
programming journey.Everytime you run your code expect to get an error.
