Question

I am wondering, if it is possible to create variables and name the using strings and other variables on Python. It would really help me on sth I’m making.

For example i want to create 10 variables:

var0
var1
var2
...

I have tried doing it with the “for” loop like this:

for i in range(10):
    'var'+str(i) = 0

but it gives me an error. Please help!

Any help would be much appreciated.

You don’t want to be using “variable variables”. You want to use a dictionary:

>>> vars = {i:0 for i in range(10)}
>>> vars
{0: 0, 1: 0, 2: 0, 3: 0, 4: 0, 5: 0, 6: 0, 7: 0, 8: 0, 9: 0}

Now you can access each element like this var[6] (and you’re not limited to integers as dictionary keys, either: var["yay!"] = "Great!").

Of course, for the special case of a range of 0 to 9, you can also simply use a list:

>>> vars = [0 for i in range(10)]
>>> vars
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
