Emmanuel in economics, this is a situation one encounters often. For instance $U(w)$ is a fonction of wealth. We use to

Thanks Emmanuel, you can see that I try intensively to learn SageMath and Python (Smile)

For the second way to install Sagemath, I will answer in a few time because all this demand a lot of time (start and res

It works nicely. In the same way, if I run docker run -p8888:8888 sagemath/sagemath:latest sage-jupyter, it propose to

I will try to answer your question step by step since I have found a way to make Sagemath work. I have installed Docker

I learn step by step. In all cases thank you.

I have this function :

def F(v,a):
       if v > a :
            return 4*a - 3*(v-a)
       else : 
            return v - 2*(a-v)^2

I want to applied it to L2 define by

L0=list(range(4))
L1=list(range(4))
L2=flatten([[(v,a) for v in L0] for a in L1],max_level=1)

The only way I found to do this is the following

Vv=[(x,F(x[0],x[1])) for x in L2]
Vv

I wonder if there is a more efficient, elegant way to do this like with apply_map().

Emmanuel you are the expert not me. But in the documentation I have read and cited in the beginning of my question it is

Nice but you are obliged to change the name of the variable.

The question is ; does this approximation has any consequences in subsequent operations ?

Thanks Emmanuel. Should I say that a the second method is always more efficient that the first, that is working directly

The two following codes accomplish the same task

1)

L=list(range(0,100,10))
Ld0=[x^2 for x in L]
Lc=[]
a=0
for i in range(len(Ld0)):
        if (Ld0[i]%6 == 0) & (Ld0[i]<= 3200) :
            Lc.append(Ld0[i])
            a+=1

2)

L=list(range(0,100,10))
Ld0=[x^2 for x in L]
Ld2=[x for x in Ld0 if (x%6 == 0) & (x<= 3200)]

which can be shown by Lc==ld2.

If I can fin easily the cpu computation time in adding %time to the first, this is not the case for the second. How to see which way is the fastest ?
