Importing modules as strings

In the form of a string, go to the module to look for the established function, and execute getattr (module name, function name, default value)

In the form of a string, the SetAttr (module name, function name/variable name, lambda expression/variable value) is set to the module.

Remove something delattr (module name, function name) from the module in the form of a string

To manipulate members of an object (a module) in the form of a string

 1  INP = input ( "  Please enter the module name:   " )  2  inp_func = input (  "  Enter the function you want to execute:   " )  3  dd = __ import__  (INP) #   import modules as strings 
 # from XXX.XX Import oo is equivalent to  __import__ (' xxx.xx.oo ', fromlist = True) 

4 # looking for a function in the module as a string if no returned none is found
5 r = Target_func ()
6 Print (r)
# in-Memory operations
Hasattr (module name, function name) # to determine if a function exists
SetAttr (module name, function name/variable name, lambda expression/variable value)
Delattr (module name, function name)

Results:

Please enter the module name: Commons
Please enter the function to execute: F1
F1
