Where to watch semantic error

Semantic errors occur when words are used incorrectly in their context or with the wrong meaning. This type of error can happen in both written and spoken language. Examples of this kind of error include mispronouncing a word, using double negatives, or mixing up homophones (words that sound the same but have different meanings). These errors can be very frustrating to deal with because they can often cause misunderstandings and confusion.

While syntax errors and runtime errors can be obvious, semantic errors can go undetected for a long time. Identifying these errors can be difficult because there is no error message that tells you what the problem is. The best way to locate these types of errors is by testing the program with a set of input values and comparing the output produced by the program to what you expect it to produce.

Syntax errors are problems that the Python interpreter finds when the program is being compiled. This type of error is usually found at the compile time and can result in an error message such as “Syntax Error: invalid syntax”. For example, missing a colon at the end of a def statement is considered a syntax error. This type of error can also occur when an expression is evaluated incorrectly, yielding a different value than expected. The following sections describe how to debug these types of errors. They are grouped by error type and each section includes tips that apply to one or more types of errors.
