This solution also helps us to avoid race conditions. Thewithstatement will hold files open even if they are deleted by a concurrent process, preventing the program from crashing. In most cases, it's considered more Pythonic to avoid exception handling. But when it comes to files, exception ...
When there is more than just two if conditions in if elif else statements, then it is referred to as if elif else ladder, as it resembles the structure of a ladder in terms of if statements. If one of the if conditions turn out to be true, then the rest of the ladder is just byp...
