  • Approach #1 : Using Inbuilt sum() Function
    Use the sum function to find the sum of dictionary values.
     

Python3




# Python3 Program to find sum of
# all items in a Dictionary
 
# Function to print sum
def returnSum(myDict):
     
    list = []
    for i in myDict:
        list.append(myDict[i])
    final = sum(list)
     
    return final
 
# 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




# 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

Python3




# 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
