• Difficulty Level : Medium
• Last Updated : 15 Nov, 2018

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`
