Could you tell me the lambda behind why there are three unused here? What is the meaning? What's the use?

 # GUI Callback function 
Def checkCallback ignoredArgs (*) : 
# only enable one checkbutton 
If chVarUn. The get () : check3 configure (state='disabled') 
The else: check3. Configure (state='normal') 
If chVarEn. The get () : check2 configure (state='disabled') 
The else: check2. Configure (state='normal') 

# trace the state of the two checkbuttons 
ChVarUn. Trace (' w ', lambda unused0, unused1, unused2: checkCallback ()) 
ChVarEn. Trace (' w ', lambda unused0, unused1, unused2: checkCallback ()) 

CodePudding user response:

Should be the three passed as a parameter to checkCallback () and then get a return value, after all your checkCallback () parameter is uncertain

checkCallback () method is not used inside unused0, unused1 and unused2 these three parameters? Can you explain it in detail?
