Read a file by strings in Python

Hi im newbie with python and i want to read a file by strings. The file has the following structure:

semilla

n_galleria t_espera t_llegada

p_ticket t_servicio

n_colosso min_colosso max_colosso

n_prisionero m_prisionero miu_prisionero sigma_prisionero

n_david

p_decision n_orcagna miu_orcagna sigma_orcagna

n_libreria p_libreria min_libreria max_libreria

until now i just have this:

f = open("/tmp/entrada.txt")
g = open("/tmp/salida.txt", "w+")

 for linea in f.readlines():
    line = linea.split(' ')


f.close()
g.close()

btw, every field at the file structure is the name of the variable. I mean, first, want to save a variable called "semilla" with the value that will be there at entrada.txt

This is a naive solution.. but easy to follow:

tokens = []    
for linea in f.readlines():
    line_content = linea.split(' ')
    for token in line_content:
        tokens.append(token)
print(tokens)

For word tokenization, it is best to use the nltk module which will handle word separators of any kind. So you can do this:

import nltk

f = open("/tmp/entrada.txt").read()

# return the list of words
words = nltk.word_tokenize(f)

And this should be more robust for any kind of text that you have.

If by "word" you mean you want to be able to iterate through every single substring delimited from the rest of the text by two spaces, you can do this:

for word in f.read().split(' '):
    do_something_to_string

There's no need to read the file by line if you don't actually need to parse it by line.
