I'm pretty new to Python and could use a hand in telling the computer what I want. I understand that 

```
A = np.array([[3,5,50],[30,2,6],[25,1,1]]

for i in A:
    print(i)

```

gives the output:

```
[3,5,50]
[30,2,6]
[25,1,1]

```

And, I understand that 

```
for i,j,k in A:
    print(i,j,k)

```

gives

```
3 5 50 
30 2 6 
25 1 1

```

But, how would you write a loop to get the following output without using a print statement three times?

```
3
5
50
30
20
6
25
1
1

```

(this is really general and I'm applying it to a large array and wanting to set specific values in the array equal to zero)
