Python program to find the sum of all elements in a dictionary

Examples :

  Input:  {’a’: 100,’ b’: 200, ’c’: 300}  Output:  600  Input:  {’x’: 25,’ y’: 18, ’z’: 45}  Output:  88 

• Approach # 1 Using the built-in function

  # Python3 Program for finding sum
# all elements in the dictionary

   
  # Function for displaying sums

  def returnSum (myDict):

   

  sum = 0

    for i in myDict:

  sum = sum + myDict [i]

   

  return sum

   
  # Driver function

  dict = { ’ a’ : 100 , ’b’ : 200 , ’c’ : 300 }

  print ( "Sum:" , returnSum ( dict ))

  Output:

   Sum: 600 

• Approach # 2 Using a For Loop to iterate over values ​​using values ​​()

  Loop over each dictionary value using values ​​() function and keep adding its to the sum.

  # Python3 Program for sum finding # all elements in the dictionary     # Function for displaying the amount def returnSum ( dict ):   sum = 0   for i in dict . values ​​(): sum = sum + i   return sum   # Driver function dict = { ’ a’ : 100 , ’b’ : 200 , ’c’ : 300 } print ( "Sum: " , returnSum ( dict ))

  Exit:

   Sum: 600 

• Approach # 3 Using the

  # Python3 Program for search sum
# all elements in the dictionary

   
  # Function for displaying the sum

  def returnSum ( dict ):

   

  sum = 0

    for i in myDict:

  < code class = "undefined spaces">  sum = sum + dict [i]

   

  return sum

    
# Driver function

  dict = { ’a’ : 100 , ’b’ : 200 , ’c’ : 300 }

  print < code class = "plain"> ( "Sum:" , returnSum ( dict ))

  Exit :

   Sum: 600
