Changing variable names with Python for loops [duplicate]

Question

I was just wondering if anyone knew of a way to change variable names based off of a for loop for something like this:

for i in range(3)      group+i=self.getGroup(selected, header+i) 

so that the names of the variables change to accomodate the data. Thanks!

You probably want a dict instead of separate variables. For example

d = {} for i in range(3):     d["group" + str(i)] = self.getGroup(selected, header+i) 

If you insist on actually modifying local variables, you could use the locals function:

for i in range(3):     locals()["group"+str(i)] = self.getGroup(selected, header+i) 

On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr function

for i in group(3):     setattr(self, "group"+str(i), self.getGroup(selected, header+i) 

And of course, I'm assuming with all of these examples that you don't just want a list:

groups = [self.getGroup(i,header+i) for i in range(3)]
