body: <p>I wish to remove all the curly brackets from my current output. My current output as shown below:</p>
  
  <pre><code> {'Chin PTE LTD': {'Carrot Cake': 22, 'Chocolate Cake': 12, 'Beer': 89}, 'COQ 
  SEAFOOD': {'GRILLED AUSTRALIA ANGU': 1, 'CRISPY CHICKEN WINGS': 1
  }}
  </code></pre>
  
  <p>My current code as shown below:</p>
  
  <pre><code>for merchant, product, quantity in big_list:
      d[merchant][product] += quantity
  
  print ({ k:dict(v) for k,v in d.items() })
  </code></pre>
  
  <p>My desired output:</p>
  
  <pre><code>'Chin PTE LTD': 'Carrot Cake': 22, 'Chocolate Cake': 12, 'Beer': 89, 'COQ

  <p>As I am still new to python, may I ask if i wish to remove the all the curly brackets in the dictionary of dictionaries. Would my desired output be achievable? If so, how should I go about doing it? Any suggestions / ideas would be appreciated. Thank you.</p>
