Define variables by iteration

Hello,
I would like to know if it would be possible to define variables iteratively.
Let's imagine that I want to create the following variables:
v1 = 1
v2 = 2
v3 = 3
...
v100 = 100
Since I don't want to write the same thing 100 times, I would like to create a loop like this:
for i in range(1,101):
v+str(i) = i
Of course, that doesn't work. Does anyone have a solution?
Thank you

Hello,
It's possible to do that. However, I think it's a very bad idea, and so I'm hesitant to explain to you how to do it.
Why don't you use a single variable, which would be an array where you could store multiple values?
Another issue, would the program know how many variables are created?
If you need to test your variables, do you want to generate everything automatically?
For example:
if v60 == 310:
# bla bla bla ...
It still remains just as lengthy to do all these tests by hand.
With arrays, as yg_be mentioned, it is much simpler.
The point I wanted to emphasize is not that generating variables in series is more or less complicated (it's easily done with exec()).
It's rather the code that will use them. We quickly end up writing a program that generates another program (code generator).
Most of the time, this is not appropriate or justifiable.
It can be justified if we want to write super optimized and fairly large code.
an example:
v={} for i in range(1,11): v[i] = i*2 for w in range(1,11): print(w,v[w])
