How to Use StringIO in Python 3

Importing the StringIO module in Python 3.2.1 may result in the error "ImportError: No module named 'StringIO'". This is because the module has been deprecated in Python 3.

To use the equivalent functionality in Python 3, utilize the io.StringIO or io.BytesIO classes instead:

<code class="python">import io

x = "1 3\n 4.5 8"
numpy.genfromtxt(io.StringIO(x))</code>

This approach resolves the TypeError that may arise when directly using Python 2's StringIO implementation in Python 3.

For compatibility with both Python 2 and 3, consider this code snippet:

<code class="python">try:
    from StringIO import StringIO ## for Python 2
except ImportError:
    from io import StringIO ## for Python 3</code>

However, it's important to note that attempting to convert a bytes object to a string implicitly in Python 3 can still lead to errors. For more information on this issue, refer to the provided Stack Overflow answer.
