Now, it is all set, and we will use various functions to mine text.

 

open(): to open files

read(): to read files

sub(): to delete the letters that are not needed 

As you can see, the words that are not essential are filtered.

nouns(): to extract nouns only

DataFrame(): to convert to the dataframe

len(): to get the the length of words 

To save the result from len(), I created a count variable and saved them here.

To sort out the words and leave valid result only

groupby(): to group data

head(): to print out top n words by frequencies

barplot(): to create a bar graph

 

To create a word cloud, first set font.

To create masks, import PIL and numpy first.

With them, you can customize the shape and color of the cloud.
