The following works:

```
sage: P.coefficients(x, sparse=0)
[4/3125*a^5 - 1/125*a^3*b + 1/25*a^2*c - 1/5*a*d + e,
-3/125*a^4 + 3/25*a^2*b - 2/5*a*c + d,
4/25*a^3 - 3/5*a*b + c,
-2/5*a^2 + b,
0,
1]
```

The variable `x`

has to be specified, if some other variables are present, and we want the coefficients only with respect to `x`

.

Note that the coefficient on the pythonical place zero corresponds to the zero degree (i.e. free) coefficient of `P`

.
So the leading coefficient is on the pythonical fifth place. In order to get "the other list" *[1,0, b - 2/5a^2,...]*, just take the reverse list.

```
sage: C = P.coefficients(x, sparse=0)
sage: C . reverse()
sage: C[0:3]
[1, 0, -2/5*a^2 + b]
```
