Screen.max_rows : int If max_rows is exceeded, change to truncate watch. Based on 'large_repr', objects are both centrally truncated or printed as being a summary see. 'None' value signifies unlimited. Pandas python In the event python/IPython is running inside a terminal and `large_repr` equals 'truncate' this can be set to 0 and pandas will vehicle-detect the height from the terminal and print a truncated object which inserts the display screen height.
