In this tutorial we are going to learn about, how to fix the ImportError: No module named six.

Before we start let us see what is six in Python.Six is a very popular Python library for number crunching and data analysis. It is a powerful library to perform mathematical operations like arithmetic, algebraic and statistical functions.

Here is an example, how the error occurs:

Then I get this:Traceback (most recent call last):  File "<pyshell#3>", line 1, in <module>    import matplotlib.pyplot as plt  File "C:Codinlibsite-packagesmatplotlibpyplot.py", line 29, in <module>    from matplotlib.figure import Figure, figaspect  File "C:Codinglibsite-packagesdateutilrrule.py", line 18, in <module>    from six import advance_iterator, integer_typesImportError: No module named six

The ImportError: No module named six error occurs one of the following reasons:

1. Using the six module without installing it.

2. Installed the module in different environment and trying to access it another environment.

3. Installed the module and the version is wrong.
