I like the pprint module in Python. I use it a lot for testing and debugging. I frequently use the width option to make sure the output fits nicely within my terminal window
If the dictionary items are all of one type, you could use the amazing data-handling library pandas:
>>> import pandas as pd
>>> x = {'foo':1, 'bar':2}
>>> pd.Series(x)
bar 2
foo 1
dtype: int64
or
>>> import pandas as pd
>>> x = {'foo':'bar', 'baz':'bam'}
>>> pd.Series(x)
baz bam
foo bar
dtype: object
