Python Syntax Errors Cheat Sheet
In Python, if you know syntax rules, you can eliminate errors. The mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Further Python is case sensitive. So using the wrong identifier gives an error.
Indentation is unique to Python. You cannot find strict indentation in any other programming language. You need to focus on the three areas while writing a Python program. To avoid errors you need to learn indentation rules.
Python raises an exception, when it encounters an error. These are called system errors.
Python Syntax Rules List
- Indentation or Syntax Errors
- Exceptions
- Handling Exceptions
1: Indentation
If you do not follow the 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 the same indentation. Not only, but the statement inside of them should also have the same indentation.
Best Examples
Understand these examples a good material on indentation for you.
2: Exceptions
Python raises an exception, when it encounters an error. These are called system errors.
Python has many built-in exceptions. One best example is ZeroDivisionError
More exceptions all list in 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:
Python Syntax Example:
try:
d = int(20)
f = str
g = d + f
except TypeError:
print('This is TypeError Exception')
else :
print('No exception happened')
d = int(20)
f = str
g = d + f
except TypeError:
print('This is TypeError Exception')
else :
print('No exception happened')
