How can I do this exercise?
"Write a program that given a text file, a delimiter, and a list of fields, print only these fields, separated by this delimiter. "
At the moment I have this:
f=open("archivo.txt","r")
delimitador=str("-")
lista=['Hola','Adios','Hoy']
I would do it this way:
f=open("archivo.txt","r")
delimitador=str("-")
lista=['Hola','Adios','Hoy']
linea = f.readline()
aImprimir = ""
primera = True
while linea != "":
palabras = linea.split(" ")
for palabra in palabras:
for clave in lista:
if clave == palabra:
if primera:
aImprimir+=clave
primera = False
else:
aImprimir+=delimitador+clave
linea = f.readline()
print(aImprimir)
The problem is that this code only works if the file read does not have line breaks, and all the words have to be separated from each other by a space. The latter does not have to be that way, just by changing the line:
palabras = linea.split(" ") #Entre estos parentesis lo que separe las palabras en el archivo
