Given a dictionary in Python, write a Python program to find the sum of all Items in the dictionary.

Examples:

Input : {'a': 100, 'b':200, 'c':300}
Output : 600

Input : {'x': 25, 'y':18, 'z':45}
Output : 88

• Approach #1 : Using Inbuilt sum() Function

  Use sum function to find the sum of dictionary values.

  
  

  
  
  

  # Python3 Program to find sum of  # all items in a Dictionary    # Function to print sum 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 For loop to iterate through values using values() function

  Iterate through each value of the dictionary using values() function and keep adding it to the sum.

  
  
  
  
  
  

  
  
  

  # Python3 Program to find sum of  # all items in a Dictionary    # Function to print sum 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))

  Output:

  Sum : 600

• Approach #3 : Using For loop to iterate through items of Dictionary

  Iterate through each item of the dictionary and simply keep adding the values to the sum variable.

  
  

  
  
  

  # Python3 Program to find sum of  # all items in a Dictionary    # Function to print sum def returnSum(dict):             sum = 0      for i in myDict:            sum = sum + dict[i]              return sum    # Driver Function dict = {'a': 100, 'b':200, 'c':300} print("Sum :", returnSum(dict))

  Output:

  Sum : 600
