Highlight main words of a text in order of a ready list

I have a very basic basis that I would like to highlight the main words of each line of a prioritization list, example:

Groundwork: 

Bom dia 
que dia lindo 
vamos embora 
vamos chutar o dia

Prioritisation list: bom dia vamos lindo

Expected result:

Bom dia - Bom 
que dia lindo - Dia 
vamos embora - vamos 
vamos chutar o dia - dia

I could find it with only one variable and not a list. Code:

texto = 'dia' 

for lin in open(r"C:\Users\guilgig\Desktop\teste.txt"): 
    if texto in lin: 
        print (texto, lin)
python

  • Why "Good morning" has only "Good" outstanding if "day" also belongs to the prioritization list?

  • Thank you for editing! then following the prioritization list because s need the most important so when he finds one of the words is already ok, but if there is a way showing all the words all right

The code you made is already very close to what you need, just set the prioritization list and scroll through it by searching the words in the sentence:

with open('teste.txt') as stream:
    for line in stream:
        for word in ['bom', 'dia', 'vamos', 'lindo']:
            if word in line:
                print(line.strip(), '-', word)
                break

See working on Repl.it

As to the with to open the file, you can read in: What’s with no Python for?. For micro-otimasons, you can define your word list with a tuple (tuple) or even a set (set), which, to this end, have advantages over both storage in memory and speed of access to the elements.

You can do it using two for:

principais_palavras = "bom dia vamos lindo"

base = """Bom dia
que dia lindo
vamos embora
vamos chutar o dia"""

lista_prioritaria = principais_palavras.lower().split(" ")
linhas = base.lower().split("\n")

for linha in linhas:
  for palavra in lista_prioritaria:
    if (palavra in linha):
      print(linha + " - " + palavra)
      break

The logic of reading the file is not part of the algorithm, so it was left out, but just adapt to your case.

    If I may comment, the idea of using the lower() is good if the intention is to disregard the text boxes, but the split() in the line to convert to a word list is unnecessary. The operator in works also for string, serving to seek if there is a substring.

  • When to the lower(), I put because I assumed that the box should be disregarded in the search, based on the example given by AP. When to split(), you’re absolutely right. I don’t know what I was thinking. I’ll make it simple. Thank you. :)
