title: Find Element In Two-Dimensional Python Array
body: <p>What I am trying to do is take a user input for as many rows as they wish, and make it into an array. After that i want to find where the highest number is in the array, an (x,y) coordinate of the number type of thing. I have created the initial array in different way but for example I have:</p>
  
  <pre><code>  import numpy as np
    m = []
    rows = eval(input("How many rows in the list:"))
    for row in range(rows):
        m.append([])
        value = eval(input("Enter a row:"))
        m[row].append(value)
    m = np.array(m)
    print(m)
    M = np.amax(m)
    print(M)
    index = np.where(M)
    print(index)  
  </code></pre>
  
  <p>The printing is just so i can see what it is doing. As a final i just want to see the last line in this example:</p>
  
  <pre><code>   Enter the number of rows in the list:3          
     Enter a row: 1,5,6        
     Enter a row: 2,6,7     
     Enter a row: 5,26,12     
     The location of the largest element is at (1, 2)
  </code></pre>
  
  <p>Extra info:    I don't care if it uses numpy of not. and i wouldn't be against using separate functions, when i think about it it might be a good idea; one to create an array and a separate to locate the largest number.</p>
  
  <p>Thanks in advance.</p>
  
  <p>PS. As the comment says, eval shouldn't usually be used because of security risks.  The only reason I am using it is because this is a quick assignment for school. </p>
