如何从给定的txt文件制作字典？

Question

Task: given a txt file with adjective \\t synonym, synonym, synonym, etc. in a line, several lines are given. I need to create a dictionary, where adjective will be a key and synonyms - a value. My code:

#necessary for command line + regex
import sys 
import re

#open file for reading
filename = sys.argv[1]
infile = open(filename, "r")

#a
#create a dictionary, where an adjective in a line is a key
#and synonyms are the value

dictionary = {}
#for each line in infile
for line in infile:
    
    #creating a list with keys, a key is everything before the tab
    adjectives = re.findall(r"w+\t$", line)
    print(adjectives)
    
    #creating a list of values, a value is everything after the tab
    synonyms = re.findall(r"^\tw+\n$", line)
    print(synonyms)
    
    #combining both lists into a dictionary, where adj are keys, synonyms - values
    dictionary = dict(zip(adjectives, synonyms))
    print(dictionary)

#close the file
infile.close()

The output shows me the empty brackets... Could someone help to fix?

Instead of regular expressions, use split() to split strings using delimiters. First split it using \\t to separate the adjective from the synonyms, then split the synonyms into a list using , .

Then you need to add a new key in the dictionary, not replace the entire dictionary.

for line in infile:
    line = line.strip() # remove newline
    adjective, synonyms = line.split("\t")
    synonyms = synonyms.split(",")
    dictionary[adjective] = synonyms

print(dictionary)
