Raised when there is an error in Python syntax. Raised when a generated error does not fall into any category. Raised when the user hits the interrupt key. Raised when indentation is not specified properly. Raised when the imported module is not found. Raised when an index is not found in a sequence. Raised when the result of an arithmetic operation is very large to be represented. Raised when division or modulo by zero takes place for all numerical values. Raised in case of failure of the Assert statement. Raised when floating point calculation fails. Some of the built-in exceptions are: Exception There are a number of defined built-in exceptions in Python which are used in specific situations. Python raises an exception when your code has the correct syntax but encounters a run-time issue that it cannot handle. ExceptionsĮxceptions occur during run-time. In simple words, a syntax error occurs when the proper structure or syntax of the programming language is not followed.Īn example of a syntax error: > print( 1 / 0 )) Syntax Errors, also known as parsing errors, occur when the parser identifies an incorrect statement. Errors occurring at run-time or Exceptions.It allows the program to answer the questions - of what, why, and how something goes wrong and then terminates the program in a delicate manner. On the other hand, exceptions act as communication tools. Why is Exception Handling Important?Īlthough exceptions might be irritating when they occur, they play an essential role in high-level languages by acting as a friend to the user.Īn error at the time of execution might lead to two things: your program will die or display a blue screen of death. It can be performed both at the software level as part of the program and also at the hardware level using built-in CPU mechanisms. A Python exception is basically a construct that signals any important event, such as a run-time error.Įxception Handling is the process of responding to executions during computations, which often interrupts the usual flow of executing programs in advanced Python projects. Python raises exceptions when it encounters errors during execution.
