Function nesting and function name Parameters

Store the sub-function name as a parameter. When you call this function again, the parameters of the Upper-layer function are still stored.

The operation for storing sub-functions is in upper-layer functions. When passed in, sub-functions can have no parameters, and parameters can be added when called.

The more chaotic, the more direct the demo

1 A = [] 2 def Adda (a1, a2): 3 def addb (A3): 4 print ('--') 5 return A1 + A2 + A3 6. append (addb) 7 print ('+ +') 8 Adda ('000000', '000000') 9 print (a) 10 for AA in: 11 AA ('a3 ') 12 print (AA ('a3 '))

Running result
