Modification of the colour of the words in QPlainTextEdit

[jeanid]

I have an object: self.textEdit = QPlainTextEdit()in code:

dark_theme = '''
QWidget{
background-color: #dedede;
}
QPlainTextEdit{
background-color: #282c34;
font: 700 16pt \"Zen Kurenaido\";
padding: 8px;
color: #aeb4b4;
border-radius: 10px;
}'''
class Ui_application_pages(object):

def setupUi(self, application_pages):

if not application_pages.objectName():

application_pages.setObjectName(u"application_pages")

application_pages.resize(1056, 657)

self.page_1 = QWidget()

self.page_1.setObjectName(u"page_1")

self.page_1.setStyleSheet(dark_theme)

self.page_1.setStyleSheet('background-color: #22252c')

self.centrallayout = QHBoxLayout(self.page_1)

self.centrallayout.setObjectName(u"centrallayout")
self.textEdit = QPlainTextEdit()
self.textEdit.setStyleSheet(dark_theme)
self.textEdit.setObjectName(u"lineEdit")

I want the word on my text editor. print Anyway, that's the word that changed its color, and the rest of the words in the line and the editor were not.

You can try just like the example below.

Look, I didn't exactly set an example and interval between the words of one gap.

index = index + len(word) + 1

If you need something more serious, check the question. https://ru.stackoverflow.com/questions/901830

text = '''Функция print

Функция print Python выводит заданные объекты на стандартное устройство 

вывода (экран) или отправляет их текстовым потоком в файл.

Полный синтаксис функции print():

print( *items, sep=' ', end='\n', file=sys.stdout, flush=False ).

Параметр file контролирует то, куда выводятся значения функции print.

По умолчанию все выводится на стандартный поток вывода - sys.stdout.

Обратите внимание на то, что все аргументы, которые управляют поведением 

функции print, надо передаватьprint как ключевые, а не позиционные.'''
