The Repeat command, executed with the dot or period key (.), is more useful than it first appears. Once learned, you will find yourself using it often.
Command:Description.Repeat the last change10.Repeat the last change 10 times
So then, for a very simple example, if you make a change to line 1 by...
Given a DataFrame with MultiIndex columns
# build an example DataFrame
midx = pd.MultiIndex(levels=[['zero', 'one'], ['x','y']], labels=[[1,1,0,],[1,0,1,]])
df = pd.DataFrame(np.random.randn(2,3), columns=midx)
In [2]: df
Out[2]:
one zero
y x ...
Start with a standard DataFrame
df = pd.DataFrame(np.random.randn(2,3), columns=['a','b','c'])
In [91]: df
Out[91]:
a b c
0 -0.911752 -1.405419 -0.978419
1 0.603888 -1.187064 -0.035883
Now to change to MultiIndex, create a MultiIndex object and assign it to df....
You can use the archivesBaseName to set the name of apk.

Sometimes you might have branches lying around that have already had their changes merged into master. This finds all branches that are not master that have no unique commits as compared to master. This is very useful for finding branches that were not deleted after the PR was merged into master.

You can take a look at the full code in this working Plunker.
In this example I use a shared service to handle the communication between the pages inside the tab (child pages) and the tab container (the component that holds the tabs). Even though you probably could do it with Events I like the shar...
