Most bugs arise from mistakes and errors made by people in either a program&#8217;s source code or its design. Usually, errors are classified as: syntax error, run-time error, and logical error.<\/p>\n<p><strong>Syntax error<\/strong><\/p>\n<p>Syntax error refers to an error in the syntax of tokens and\/or sequence of tokens that are intended to be written in a particular programming language. For compiled languages, syntax errors occur strictly at compile-time. A program will not compile until all syntax errors are corrected. For interpreted languages, however, not all syntax errors can be reliably detected until run-time.<\/p>\n<pre>&gt;&gt;&gt; prin ' Hi '\r\nSyntaxError: invalid syntax \r\n&gt;&gt;&gt; print \" Hi '\r\nSyntaxError: EOL while scanning string literal<\/pre>\n<p><strong>Run-time error<\/strong><\/p>\n<p>A run-time error is an error that can be detected during the execution of a program. The code appears to be correct (it has no syntax errors), but it will not execute. For example, if a programmer has written a correct code to open a file using the open ( ) function, and if the file is corrupted, the application cannot carry out the execution of the open ( ) function, and it stops running.<\/p>\n<p><strong>Logical error<\/strong><\/p>\n<p>A logical error (or semantic error) is a bug in a program that causes it to operate incorrectly, but not terminate abnormally. A logical error produces an unintended or undesired output or other behavior, although it may not immediately be recognized. The logic error occurs both in compiled and interpreted languages.<\/p>\n<p>Unlike a program with a syntax error, a program with a logical error is a valid program in the language, though it does not behave as intended. The only clue to the existence of logic errors in the production of wrong solutions. For example, if a program calculates the average of variables a and b, instead of writing the expression c= (a+b) \/ 2, one can write c=a+b \/ 2, which is a logical error.<\/p>\n<pre>&gt;&gt;&gt; print a+b \/ 2 \r\n6 . 5\r\n&gt;&gt;&gt; print ( a+b ) \/ 2\r\n5 . 0<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>In this Page, We are Providing Basics of Python \u2013 Error.
