Regarding Python's tfidf and word-cloud
I recently was working with word-cloud and I saw that the words in the image are bigger or smaller with respect to their importance in the document.
TFIDF is somewhat similar to it.
But I could not understand underlying working philosophy of WordCloud how does it work, how does it calculate the importance of a word.
If we have wordCloud why do we need TFIDF and vice-versa
Also if we have calculated result from TFIDF how to visualize it.
Please help me I feel this things would be very helpful to build the foundation
Thank you in advance

You are probably overthinking it. You don't point out the exact implementation of "word cloud" that you are looking at, but most do not bother to verify the "importance" of a word, only their relative frequencies in the entire source text. Which is why they need a list to weed out common words – if not, "the" and "an" and "of" would be the largest words for almost all texts.
