Syntax errors are errors in your code such as a missing semi-colon. Run time errors are errors that appear during run time such as an infinite loop. Logic errors appear when your code does not do what you want it to do because of the logic such as the comparisons are wrong.
List of Error Messages. Click on the name of the message for an explanation of what may have caused it, and a suggestion or two on how to fix the problem. 1  SyntaxError: invalid syntax. 2  IndentationError: expected an indented block. 3  IndentationError: unexpected indent. 4  NameError: global name '---' is not defined.Python knows the purposes of certain names (such as names of built-in functions like. ). Other names are defined within the program (such as variables). If Python encounters a name that it doesn't recognize, you'll probably get this error.he syntax of a language is the set of rules that define what parts of the language can appear in which places. If you insert tab A into slot B, so to speak, you'll create a statement that has invalid syntax. Because there are lots of slots in Python that don't accept most tabs, generating a syntax error is not hard.
