Python Syntax Rules Eliminate Errors Before you start debugging

In Python, if you know syntax rules, you can eliminate errors. The basic mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Python is case sensitive. So using the wrong identifier gives an error.

Indentation is unique to Python. You cannot find this kind of rule in any other programming languages

Python Syntax Cheat Sheet

These are the main areas you need to focus while writing a Python program. You need to learn rules. Else you need to waste a lot of time fixing the issues or errors.

1. Indentation or Syntax Errors
2. Exceptions
3. Handling Exceptions

1. Indentation

If you do not follow proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that.

• In if loop, the if, elif, and else should have same indentation. Not only, the statement inside of them should have same indentation.
• Understand these examples a good material on indentation for you.  

2. Exceptions 

Python raises exception, when it encounters an errors. These are called system errors.

• Python has many built-in exceptions. One best example is ZeroDivisionError
• More exceptions all list at one place.

3. Handling Exceptions

To handle exception you need two blocks which are Try and Except. Try Block is the block where you can give your code. Except is the Block where your exception message comes here.

Python Syntax Example:

try:
    d=int(20)
    f=str
    g=d+f
except TypeError:
    print ('This is TypeError Exception')
else:
    print ('No exception happened')

In the above example, except shows error when you get an exception.
