How to speed up the code?

Question

Python

b = list(map(int,input().split()))
d = []
j = 0
x = 0
for i in range(len(b)) :
    x = 0
    for j in range(len(d)):
        if b[i] >= d[j]:
            x += 1 
        elif x > 0:
            break
        else:
            j = 0
            break
    d = d[x:]
    d.append(b[i])
    d.sort()
    print(len(d))
