You mean run once after a set of data, this set of data at the next rerun when needed? It can only be saved to the local first, run read again next time,

If it is stored in the memory, can copy a list on a temporary variable
If you want to save in the disk, can be serialized to a file, such as:

 import pickled 

A=,4,5,6,7,8,9 [3] 

# in the file 
Pickle. Dump (a, open (r "c: \ xx. D," 'wb)) 

# from the file 
X=pickle. The load (open (r "c: \ xx. D," 'rb')) 
Print (x)
