Now that Anaconda is installed, we can check the version of pandas that is installed either from within the Python interpreter or from the command line. The means to perform both of these is the same on each platform, and this will be demonstrated from an OS X terminal.
From within the Anaconda Python interpreter, you can check the version of pandas on the system by importing pandas and then examining the version with the following two Python statements:
>>>import pandas as pd >>>print (pd.__version__)
The preceding commands will then report the version of pandas. The following screenshot shows that v0.14.1 is the currently installed version:
This has reported that pandas version is 0.14.1, which is not the most recent, so we may want to update.
You can also check the pandas version using the conda package manager from the command line as follows (which also reports that version is 0.14.1):
Michaels-MacBook-Pro:~ michaelheydt$ conda list pandas # packages in environment at //anaconda: # pandas 0.14.1 np19py27_0 Michaels-MacBook-Pro:~ michaelheydt$
To update pandas to the most recent version, use the following conda command:
Michaels-MacBook-Pro:~ michaelheydt$ conda update pandas Fetching package metadata: .. Solving package specifications: . Package plan for installation in environment //anaconda: The following packages will be downloaded: package | build ---------------------------|----------------- conda-3.7.3 | py27_0 156 KB numpy-1.9.1 | py27_0 2.9 MB pandas-0.15.1 | np19py27_0 4.6 MB pytz-2014.9 | py27_0 175 KB requests-2.5.0 | py27_0 586 KB setuptools-7.0 | py27_0 436 KB ------------------------------------------------------------ Total: 8.8 MB The following packages will be UPDATED: conda: 3.7.0-py27_0 --> 3.7.3-py27_0 numpy: 1.9.0-py27_0 --> 1.9.1-py27_0 pandas: 0.14.1-np19py27_0 --> 0.15.1-np19py27_0 pytz: 2014.7-py27_0 --> 2014.9-py27_0 requests: 2.4.1-py27_0 --> 2.5.0-py27_0 setuptools: 5.8-py27_0 --> 7.0-py27_0 Proceed ([y]/n)?
We can see that pandas can be updated to v0.15.1, along with all required dependent packages. Press Enter to proceed. The conda package manager will retrieve and install the required packages:

You can check whether pandas v0.15.1 is installed with conda:
Michaels-MacBook-Pro:~ michaelheydt$ conda list pandas # packages in environment at //anaconda: # pandas 0.15.1 np19py27_0 Michaels-MacBook-Pro:~ michaelheydt$
The pandas library is now updated. This can also be verified from within the Python interpreter as shown in the following screenshot:
