fpdf python细胞消失

Question

I created this program in github that converts quizlet flashcards into large printable ones because quizlet has removed that feature. The one on github works however it doesn't work with larger bits of text. I have changed it to make the font smaller when it doesnt fully fit. However the cell would just disappear. I thought the font was just zero but that's not the case. Even when trying the way below, cells just vanish. As shown here

from fpdf import FPDF
import os, math, re, numpy

def group_words(s, n):
    words = s.split()
    for i in range(0, len(words), n):
        yield ' '.join(words[i:i+n])

def printcell(text):
    #105 is the width of 1 cell
    width = pdf.get_string_width(text)
    pdf.set_font("Japanese", size = fontsize)

    if(width >= 104):
        pdf.set_font("Japanese", size = fontsize-5)
        print("splitting")
        words = numpy.array(list(group_words(text,3)))
        print(words)
        words.join('\n')  
        print(words)
        pdf.cell(105, 74.25, words, 1, 1, 'C')
    else:
        pdf.cell(105, 74.25, text, 0, 1, 'C')

here is the earlier version that changes font size(i am aware there is no check to make sure the font is not 0):

def printcell(text):
    while(pdf.get_string_width(text)>105):
        if (counter == fontsize):
            pass
        else:
            pdf.set_font("Japanese", size = fontsize-counter)
            counter+=1
    pdf.cell(105, 74.25, text, 0, 1, 'C')

Answer 1

Try

pdf.cell(105, 74.25, str(words), 1, 1, 'C')

and you might find that you want

words = '\n'.join(list(words))
