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

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
