Part A$.$ Write a function wordDictFromFile$()$ that processes a file and aggregates word counts into a dictionary. The function takes a filename parameter:

filename, an input file containing multiple lines in the format

word:count word:count $...$

where word is a string and count is an integer. The function returns a dictionary of key: value pairs, where each key is a word from the file and its corresponding value is the total count for that word.

For example, if an existing input file, input.txt$,$ contains:

it:$3$ is:$2$ fun:$12$ what:$1$

python:$1$ is:$1$ fun:$3$

print$($wordDictFromFile$(\text{'}$input$.$txt$\text{'}))$ will display

$\{\text{'}$it$\text{'}$:$3,\text{'}$is$\text{'}$: $3,$ 'fun': $15,$ 'what': $1,$ 'python': $1\}$

Part B$.$ Given the existing file input.txt and a target count $=5.$ Write code that utilizes the

wordDictFromFile $()$ function to produce and print on the screen the list of distinct words with a total word count no more than target. The output for the given example would be $[\text{'}$it$\text{'},\text{'}$is$\text{'},$ 'what $\text{'},$ 'python'$]$
