Trying to randomly find a job will get you nowhere. PREPARE, PLAN, and RESEARCH, and you will find a job that is meant for you.


If you have attended a get-together of friends or a social gathering off-late, chances are that you would have come across at least half a dozen people, talking about their jobs; how they are unhappy with it and looking for a change, or how difficult it seems to get one in the first place.
Job Search 

Searching for a job has become one of the most time-occupying tasks in recent times. Almost as difficult as getting one, a job search means researching, identifying, and applying for jobs and going through the functions of interviews, discus…

Python Syntax Errors Cheat Sheet

By
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.

Python Syntax Rules List


Python syntax cheat sheet

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.

  • 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:

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

How to Use Python Try and Except Logic Correctly

By
Image
Error catching is common in any programming language. In Python, you can code Try, and Except Logic to catch the error.




The programmer can tell Python what to do if specific errors occur by writing some code that deals with the problem. If the programmer did not do this, then the default is for Python to print an error message that describes the error and then stop executing the program. 

Error messages can be seen as a failure on the part of the programmer to handle errors correctly.

Syntax to Write Try and Except in Python.

try:       c = a/b except:       c = 1000000
How 'Try' works here. The above syntax says that the Try ends with ':'. That means, in Python, that is the block of Try.

The programmer's logic comes in the Try block.

The Except: is another block. That means in this block programmer can specify some value. And that value populates when any error happens.

So far so good.

Try and Except Popular Examples.Example: 1
try:       c = a/b exceptZeroDivisionError: c = 100…

UNIX operating system has some special keys. These you can use to interrupt the program processing or to resume it. The file management and keys totally different in UNIX kinds of operating systems. 



An example of a UNIX special key and its use.
Special Keys in UNIX much useful to take action  when something happens.

1. Why You Need Program Interruption in UNIX.

A scenario where you made some mistake in the input command and you need to stop the further process. Then you can use the CTRL+C command. It is equal to the DELETE command.

2. List of UNIX Special Keys.

RETURN key 
The RETURN key signifies the end of a line of input. On any terminal, RETURN has a key of its own, or return may be typed by holding down the control key and typing a 'm'.
CTRL-m Key
Hint: Ctrl-m command is equal to RETURN key in Unix systems


DELETE Key
The DELETE key stops a program/command immediately, without waiting for it to finish. DELETE can be achieved equivalently with ctrl-c.
Hint: Ctrl-c Command you can use …
