In WordCloud on Python I would like to merge two languages

问题

In WordCloud on Python I would like to merge two languages ​​into one picture (English, Arabic) but I was unable to add the Arabic language as you see a squares instead of words and when I call the Arabic_reshaper library and make it read the csv file It shows me the Arabic language and make the English language as a squares

    wordcloud = WordCloud(
                          collocations = False,
                          width=1600, height=800,
                          background_color='white',
                          stopwords=stopwords,
                          max_words=150,
                          random_state=42,
                          #font_path='/Users/mac/b.TTF'
                         ).generate(' '.join(df['body_new']))
print(wordcloud)
plt.figure(figsize=(9,8))
fig = plt.figure(1)
plt.imshow(wordcloud)
plt.axis('off')
plt.show()

see her a put two languages ,but see a squares instead of words arabic

a wont like this max two languages

I've been struggling with the same problem for a while now and the best way to deal with it is the generate_from_frequencies() function. You also need a proper font for Arabic. 'Shorooq' will work fine and available online for free. Here is a quick fix to your code:

from arabic_reshaper import arabic_reshaper
from bidi.algorithm import get_display
from nltk.corpus import stopwords
from itertools import islice


text = " ".join(line for lines in df['body_new'])
stop_ar = stopwords.words('arabic') 
# add more stop words here like numbers, special characters, etc. It should be customized for your project

top_words = {}
words = text.split()
for w in words:
    if w in stop_ar:
        continue
    else:
        if w not in top_words:
            top_words[w] = 1
        else:
            top_words[w] +=1

# Sort the dictionary of the most frequent words
top_words = {k: v for k, v in sorted(top_words.items(), key=lambda item: item[1], reverse = True)}

# select the first 150 most frequent words
def take(n, iterable):
    "Return first n items of the iterable as a list"
    return list(islice(iterable, n))
for_wc = take(150, top_words.items())

# you need to reshape your words to be shown properly and turn the result into a dictionary
dic_data = {}
for t in for_wc:
    r = arabic_reshaper.reshape(t[0]) # connect Arabic letters
    bdt = get_display(r) # right to left
    dic_data[bdt] = t[1] 

# Plot
wc = WordCloud(background_color="white", width=1600, height=800,max_words=400, font_path='fonts/Shoroq.ttf').generate_from_frequencies(dic_data)
plt.figure(figsize=(16,8))
plt.imshow(wc, interpolation='bilinear')
plt.axis("off")
plt.show()

Important:

get_display() or reshape() might give you error. It is because there is a weird character in your text that these functions are unable to deal with. However finding it should not be so difficult as you only use 150 words to display in your plot. Find it and add it to your Stop Words and rerun the code.
