A script processes a log file and needs to count the number of times each error code appears. The script reads each line, extracts the error code, and stores it. Which data structure is best for accumulating the counts?

A list of error codes, then use `list.count()` for each unique code.

A set of error codes, then use `len()` to get the count.

A tuple of error codes, then use `tuple.count()` for each unique code.

A dictionary mapping each error code to its count, incrementing the count for each occurrence.

A script reads a numeric value from a configuration file and uses it in a calculation. The value may be an integer or a float. The script must handle both cases without crashing. Which code snippet is most appropriate?

```python value = eval(open('config.txt').read().strip()) ```

```python value = int(open('config.txt').read().strip()) ```

```python value = float(open('config.txt').read().strip()) ```

```python value = open('config.txt').read().strip() ```
