The dream of every software programmer is to write a program that runs smoothly. However, this is not usually the case at first. The execution of a code stops in case of an error. Unexpected situations or conditions might cause errors. Python considers these situations as exceptions and raises...
Assertions are simply boolean expressions that check if the conditions return true or not. If it is true, the program does nothing and moves to the next line of code. However, if it's false, the program stops and throws an error. ...
So if your code relies on assert to check something that's actually important for your code to function, make sure your code isn't ever run with the optimize flag enabled, or those assertions won't be run!Here's an example of code that relies on an assertion to check something ...
Assertions are boolean expressions that must be true for the code to be correct. Assertion failures result in code correction. Exceptions are indications about non-typical situations that can occur at runtime. Exceptions may not result in fixing the code. For instance, if the Internet connection ...
