Spyder does not autocomplete local variables

Question

I'm having a problem getting my local variables autocompleted. This is a very basic functionality which I'm sure it should support. When I'm starting to write a variable name which was already declared, and press TAB (this is the default shortcut), I get nothing. Is this a bug?

Answer 1

(Spyder dev here) Spyder does complete local variables but to have this functionality you need to install a library called rope. You can do it by running this command in a terminal

pip install rope

If you use Python 3 this command needs to be

pip install rope_py3k

Besides, code completion on the Editor works now with both Ctrl+Space and with Tab.

Edit: Updated answer for the Spyder version 2.3.0.

Answer 2

Another hint:

If you want to customize the shortcut (for example, your 'ctrl+space' is already occupied), try

Tools--Preferences--Keyboard shortcuts--code completion

you can change it to whatever you want

Answer 3

Idoda, I made a little guide to install Python for scientific computing on Ubuntu or Debian from their repositories. I tested correctly using Python 3 on Ubuntu 14.04 LTS.

It summarizes as follows. First, install the interpreter and the package manager:

sudo apt-get install python3 python3-pip 

Now install the Spyder's IDE:

sudo apt-get install spyder3

Thanks to Carlos Cordoba's advice, if you want to enjoy the autocomplete execute:

sudo pip3 install rope_py3k

Finally, open Spider and check if the autocomplete works rightly.

Answer 4

In my case, with the command conda install spyder, the installation process prompted me with the following...

The following NEW packages will be INSTALLED:

rope:   0.10.5-py36_0 conda-forge
spyder: 3.1.4-py36_0  conda-forge

Proceed ([y]/n)? y

I want to point out that my anaconda installation is for python 3. After this auto-completion was working. I'm utilizing OS X El Capitan.

Answer 5

Usually, ctrl+space is set to code completion in Tools -> Preferences -> Keyboard shortcuts -> code completion We have the option to change it to another shortcut.
