Qunti are composed of multiple zu (组, group) objects. ### qunti operations In an update operation, one qunti is used to update another. Any zus in the updating qunti that are not in the updated qunti are appended to the updated qunti. Any zus that are in the updating qunti and the updated qunti replace the corresponding zus in the updated qunti. The following example illustrates a qunti update operation in which an ```alpha``` zus is replaced and a ```delta``` zus is appended: ```Python # example qunti update: a = [['alpha', '10'], ['beta', '20'], ['gamma', '30'], ['gamma', '15']] b = [['delta', '40'], ['alpha', '50']] # update of a with b: a = [['beta', '20'], ['gamma', '30'], ['gamma', '15'], ['delta', '40'], ['alpha', '50']] ``` The following example illustrates qunti symmetric difference, intersection and update operations. In the update operation, two old ```gamma``` zus are replaced by a single new ```gamma``` zu: ```Python # example qunti symmetric difference, intersection and update: a = [['alpha', '10'], ['beta', '20'], ['gamma', '30'], ['gamma', '15']] b = [['delta', '40'], ['alpha', '50'], ['gamma', '25']] # symmetric difference of a and b: [['beta', '20'], ['delta', '40']] # intersection of a and b: [['alpha', '10'], ['gamma', '30'], ['gamma', '15'], ['alpha', '50'], ['gamma', '25']] # update of a with b: a = [['beta', '20'], ['delta', '40'], ['alpha', '50'], ['gamma', '25']] ``` ## data visualisation Datavision provides utilities for data visualisation. It can visualise matrices as colormaps:    It can visualise histograms:  It can visualise graphs and histograms in a terminal: ``` │ ┼+79.548 ○ │ │ ○ │ │ ○ │ │ ○ ◽ ◽ ◽ ○ │ ◽ ○ │ ○ ◽ ───○┼──────○───────○───────────────────────◽────────────────────────────────┼─── │ +0.046 ◽ +8.97638 │ │ ◽ │ │ ◽ ┼-48.228 │ ◽ │ ``` ``` │ ┼+75503.2 ∘∘|∘ ∘||||∘ ||||||∘ ∘||||||| ||||||||∘ ∘||||||||| ||||||||||∘ ∘||||||||||| |||||||||||∘ ∘|||||||||||| |||||||||||||∘ ||||||||||||||∘ ∘|||||||||||||||∘ ∘|||||||||||||||||∘ ∘|||||||||||||||||||∘ ∘∘∘||||||||||┼+1603.2|||∘∘∘ ──┼--------------------------------------------┼── -4.69099 │ +4.6147 ``` # prerequisites ## Python 2 or Python 3 ```Bash sudo apt-get -y install python sudo apt-get -y install python3 ``` ## matplotlib ```Bash sudo apt-get -y install python-matplotlib sudo apt-get -y install python3-matplotlib ``` ## shijian - <https://github.com/wdbm/shijian>
