Transfer and write three lines into python: help

Hi all,

Please anyone help me in writing the following lines in python:

clear all; 
clc; 
x=[5,31,41,51,61]
y=[1,11,21,31,5;4,14,24,34,5;
   7,17,27,37,5;34,44,54,64,5;37,47,57,67,5]
for i length(x):-1:1
    if (sum(y==x(i),'all')<.1)
        x=x-(x>y(i))
    end 
end 

in python:

import numpy as np
x=np.array([5,31,41,51,61])
y=np.array([[1,11,21,31,5],[4,14,24,34,5],
            [7,17,27,37,5],[34,44,54,64,5],[37,47,57,67,5]])
for i in range(len(x)-1,2,-2):
    if (np.sum(y==x[i],'all')<.1):
        x=x-(x>y[i])

This is a Matlab forum, so this isn't the right place to ask for help with python.

I don't see why the code you wrote wouldn't do what you expect. The only thing I notice is that you have the number 2 as argument to the range function, while in Matlab your step size is 1. Are you sure that is correct?

1. The numpy.sum doesn't take 'all'
2. The for loop needs to be adjusted to 0-base

import numpy as np
x=np.array([5,31,41,51,61])
y=np.array([[1,11,21,31,5],[4,14,24,34,5],
            [7,17,27,37,5],[34,44,54,64,5],[37,47,57,67,5]])
for i in range(len(x)-1,0,-1):
    if (np.sum(y==x[i])<.1):
        x=x-(x>y[i])

print(x);
