Erros comuns
forgetting to close file leading to resource leak; using write on read-only mode; not handling exceptions.

Nuance
The file is not closed automatically; relying on garbage collection may delay closure; better to use with statement for safety; writing large strings may consume memory.
Efeito pragmático

Dica de memória
Open, write, done — but remember to close.
Nota
Remember to close the file or use a with statement to avoid resource leaks; relying on garbage collection may delay closure.
