Description: The dez statistic, the number of descents of a permutation after replacing fixed points by zeros.

This descent set is denoted by $\operatorname{ZDer}(\sigma)$ in [1].

Code:
def statistic(x):
    Z = sz(x)
    d = 0
    for i in range(len(Z)-1):
        if Z[i] > Z[i+1]:
            d += 1
    return d

#Returns the word (as a list) where fixed points of perm are changed to zero (see [2])
def sz(x):
    l = list(x)
    for i in x.fixed_points():
            l[i-1] = 0
