Thank you Niles it works well for my needs

A lambda function might be the quickest workaround:

plot(lambda t: f(10000000,1,0.01,t),3,20)

And if you don't want to get the deprecation warning about range not taking float inputs, you could modify your function to:

def f(a,b,c,x):
    xtemp=a
    for i in range(b,ceil(x)):
        xtemp=xtemp-xtemp*c
    return xtemp

Hello, I have the following code:

def f(a,b,c,x):
    xtemp=a
    for i in range(b,x):
        xtemp=xtemp-xtemp*c
    return xtemp   
var('t')
plot(f(10000000,1,0.01,t),3,20)

and got the error

TypeError: range() integer end argument expected, got
sage.symbolic.expression.Expression.

I understand that range does nor support 'var' object, but how can I have a variable range in this kind of function?

I am not very confortable with the notebook interface to edit long files (no colorisation, etc...), but I would like to be able to use interact objects. Is there a way to:

1. Create a file in a text editor of my choice
2. run it in sage
3. have the ouput automatically opened in the browser

Thanks for your answers
