Load options:!symThere are two types of symbolic loading options. The first class is the Noisy/quiet,noisy option to print the details of the symbol loading, and the Quiet option ignores the information. The second class is prompts/prompts off, that is, whether to allow prompt execution (prompts) dialogs.The load Options command is typically executed bef

Data merge
In pandas, you can merge data through merge.
Import NumPy as Npimport pandas as Pddata1 = PD. DataFrame ({' Level ': [' A ', ' B ', ' C ', ' d '], ' numeber ': [1,3,5,7]}) data2=pd. DataFrame ({' Level ': [' A ', ' B ', ' C ', ' e '], ' numeber ': [2,3,6,10]}) print (DATA1)
The result is:
