## each one takes each variable and seperates it into 2 indexes, puts the greater into temp list, and merges with other list till temp is ordered
## for i in temp:
## print(i.name)
return temp
#returns list temp(ordered)
t = tennisPro()
s = t.sort("name")#sorts self.players depending on varialbe put in quotes
for i in t:#for i in sorted list
print(i)#prints answer
```

this is my code for a project i'm working on. however, when i run it, it says that t = tennisPro() is not defined. is there any way for me to fix this?

thanks in advance.
