Import Pandas Into Python

Question

I just installed Python 3.5.2. I am working in the shell/IDLE environment and attempting to import Pandas.

However when I write: import pandas

I get the following:

Traceback (most recent call last):
  File "C:/Users/bartogre/Desktop/Program1.py", line 1, in <module>
    import pandas
ImportError: No module named 'pandas'

How do I add any module to the library Python 3.5.2 is reading? I do not want to work in Anaconda.

I watched this video: https://www.youtube.com/watch?v=ddpYVA-7wq4

And below is my output from CMD:

C:\Users\bartogre>
C:\Users\bartogre>cd c:\users\bartogre\desktop\pyodbc-master
c:\Users\bartogre\Desktop\pyodbc-master>python setup.py

Solution

A bit of background: a system can have multiple Python installations. On Windows, each is a directory with python.exe and Lib/site-packages/. To use a package with a particular python.exe, you must install into the corresponding site-packages.

In your case, 'python' invokes 'C:\Program Files (x86)\Anaconda3\python.exe'. Do you have another python installation that you want to be working with?

In any case, the current standard way to install packages on Windows is with pip. The best way to run it in the console is

some/path> <some python> -m pip install package 

where <some python> is either python to invoke the default install or something else to get another install. Pip first goes to pypi.python.org to find the package. If the package contains C code, it may find an appropriate pre-built binary or try to compile locally, which requires the correct version of Visual C++ compiler.

If pip does not find a pre-built binary for your install, I would do the following. For about 200 packages, unofficial binaries are available at http://www.lfd.uci.edu/~gohlke/pythonlibs/. The site has been up for up, and a livesave for Windows users, for at least a decade and I and many others have used it. Cristoph gives instructions on how to download a file and then use pip to install it.

@ Terry - I am trying to install the modules to Python 3.5 located here: C:\Users\bartogre\AppData\Local\Programs\Python\Python35-32\ What is PIP? A web search takes me to pypi.python.org/pypi/pip If I read your answer correctly I would need to.... 1) Install PIP 2) Run the command C:\Users\bartogre\AppData\Local\Programs\Python\Python35-32\‌​> <python.exe> -m pip install pandas 3) Done?

pip = python installer program, or something like that. To solve the bootstrap problem -- how to install the installer, a version of pip is included with the PSF python.org installer. '-m pip' runs the installed pip package. So skip 1). Note that the installed pip can update itself. <python> -m pip -h will display general help message. pip install -h will display install-specific help. Try 2).

If 2) does not work because it cannot compile, use the alternative I outlined to get a compiled binary ready to install. pip installs 'wheels', denoted xyz.whl, I believe.
