How to Use StringIO in Python 3?

StringIO Module in Python 3

In Python 3, the StringIO module is deprecated and replaced with the io.StringIO module from the io package. Python 3 error messages suggest this transition, indicating that StringIO is "gone" and "there is no such module."

To use StringIO in Python 3, replace StringIO with io.StringIO in your code. This updated import statement will direct you to the revised io module.

import io
x = "1 3\n 4.5 8"
data = io.StringIO(x)
numpy.genfromtxt(data)

Additionally, Python 3 offers io.BytesIO for handling binary data. To support both Python 2 and Python 3 code, you can employ a try-except block:

try:
    from StringIO import StringIO  # for Python 2
except ImportError:
    from io import StringIO  # for Python 3

This approach ensures compatibility by using the correct StringIO module based on the Python version.
