Я пытаюсь привязать функцию (в .py) к кнопке (в кв.) После выбора каталога с помощью Filechooser (все на одном экране) следующим образом:
.py:
class SyllWindow(Screen): #screen where all happens
def select(self, *args):
if args[1]:
filepath = args[1][0]
try: self.label.text = filepath
except: pass
def output_csv(corpus_root): #function
corpus = PlaintextCorpusReader(corpus_root, '.*') #this must be irrelevant actually
def reduce_dip(corpus_string):
corpus_string = corpus_string.replace("Ei", "ö")
corpus_string = corpus_string.replace("ei", "ö")
# reduced
corpus_string = corpus_string.replace("ie", "ö")
return corpus_string
vowels = [' ','a','e','i','o','u','ä','ö','ü','A','E','I','O','U','Ä','Ö','Ü']
cfd_syll = nltk.ConditionalFreqDist(
(textname, num_syll)
for textname in corpus.fileids()
for num_syll in [len(w) for w in ''.join(char for char in reduce_dip(corpus.raw(fileids=textname)) if char in vowels).split()])
syll_dataframe = DataFrame(cfd_syll)
return syll_dataframe.to_csv(path + '\silben.csv')
pass
.kv (блок кнопок):
Button:
text: '.csv'
font_size: 14
on_release: self.output_csv(self.filepath)
Выглядит так:
После нажатия «.csv» Я получаю сообщение об ошибке AttributeError: 'Button' object has no attribute 'output_csv' Мне известны подобные проблемы, описанные здесь , здесь и здесь , но все примеры приведены на языке Python, в то время как моя проблема, кажется, больше связана с языком Kivy.
Буду признателен за любой совет.
