So here is a file

APPLE: toronto, 2018, garden, tasty, 5

apple is a tasty fruit

>>>end 

apple is a sour fruit

>>>end

grapes: america, 24, organic, sweet, 4

grapes is a sweet fruit

>>>end

This is a file which also has new line characters.
I want tp create a dictionary using the file. it goes like this

the function is def f(file_to: (TextIO))-> Dict[str, List[tuple]]

file_to is file name entered and it will return the dictionary like,

{'apple': [('apple is a tasty fruit', 2018, 'garden', 'tasty', 5), (apple is a sour fruit)], 'grapes':['grapes is a sweet fruit', 24, 'organic', 5)]}

each of the fruit is key and their discription is values as formatted there. Each fruits ends at >>>end

I tried

with open (file_to, "r") as myfile:

    data= myfile.readlines()

return data

it returns the file strings in a list with /n I'm thinking I can use strip() to remove that and get the element that comes before ':' as keys.

The code I tried is

from pprint import pprint

import re

def main():

    fin = open('f1.txt', 'r')



    data = {}

    key = ''

    parsed = 

    for line in fin:

        line = line.rstrip()

        if line.startswith('>'):

            data[key] = parsed

            parsed = 

        elif ':' in line:

            parts = re.split('W+', line)

            key = parts[0].lower()

            parsed += parts[2:]

        else:

            parsed.insert(0, line)



    fin.close()

    pprint(data)





main()

It's not giving the right expected result :(

I don't think that you really need re and pprint. I have tried with an easy list comprehension and some if statements.

def main:

    data = {}

    key = ''

    parsed = 

    for line in fin:

        line = line.rstrip()

        if line.startswith('>'):

            continue # If we get a line which starts with a '>', we can skip that line.

        elif ':' in line:

            parts = line.strip().split(":")

            key = parts[0].lower()



            firstInfo = parts[1].split(",") # What we have to add in the value, after reading the next line

            firstInfo.pop(0) # Removing the first element, The State name (as it is not required).



            secondInfo = fin.readline().strip() # Reading the next line. It will be the first value in the list.



            value = [secondInfo]



            value.extend([x for x in firstInfo]) # Extending the value list to add other elements.



            data[key] = value



    print(data["apple"])

    return data

If you encounter any problem with this implementation, I will be happy to help. (although this is self explanatory :P)

I made some adjustments to your code (which I gave you in a previous post). I think this gives what you want with your updated data.

The data:

APPLE: toronto, 2018, garden, tasty, 5

apple is a tasty fruit

>>>end

apple is a sour fruit

apple is ripe

>>>end

apple is red

>>>end

grapes: america, 24, organic, sweet, 4

grapes is a sweet fruit

>>>end

And here is the updated code:

import re



def main():

    fin = open('f1.txt', 'r')



    data = {}



    for line in fin:

        line = line.rstrip()

        if line.startswith('>'):

            if key not in data:

                data[key] = [tuple(parts)]



        elif re.match('^w+:s', line):

            key, _, *parts = re.split('[:,]s+', line)

        else:

            if key in data:

                data[key].append(line)

            else:

                parts.insert(0, line)



    fin.close()



    for key in data:

        if len(data[key]) > 1:

            data[key][1] = tuple(data[key][1:])

            del data[key][2:]



    print(data)





main()

The output from this revised data and code is:

{'APPLE': [('apple is a tasty fruit', '2018', 'garden', 'tasty', '5'), ('apple is a sour fruit', 'apple is ripe', 'apple is red')], 'grapes': [('grapes is a sweet fruit', '24', 'organic', 'sweet', '4')]}
