I'm having trouble working through this code in Python - I'm new to Python but have used SQL languages and I don't know if I'm getting them confused or what. the problem is:

"Write a function in the cell below that iterates through the words in file_contents, removes punctuation, and counts the frequency of each word. Oh, and be sure to make it ignore word case, words that do not contain all alphabets and boring words like "and" or "the". Then use it in the generate_from_frequencies function to generate your very own word cloud!"

My code is attached...

And then when I try to get the word cloud to appear - I get the following error:

NameError: name 'file_contents' is not defined - this is related to the my_image line in the section right above this.
