使用列表理解，而不是循環在python

Question

def interval(a,b,n): 
    dx = float(b-a)/(n+1) 
    cnt = 1 
    points = [a] 
    xj = a 
    while cnt <= n+1: 
     xj += dx 
     points.append(xj) 
     cnt+=1 
    return points 

Answer 1

更換你的函數如下給出： -

def interval(a,b,n): 
    dx = float(b-a)/(n+1) 
    points = [a] 
    xj = a 
    points.extend([xj + (i * dx) for i in xrange(1, n+2)]) 
    return points
