将txt文件转换为python中的字典

Question

I was trying to read a txt file and convert it to a dictionary in python, the txt file has list of countries with their per capita income eg "Quatar $129,700 Monaco $78,700,,,," when I tried to solve the problem the out put I am getting is " 'Quatar $129': 700 " I could not figure out why?

with open("dict.txt") as file:
for line in file:
    (key, val) = line.split()
    dictionary[int(key)] = val

print (dictionary)```

Answer 1

In your case:

with open("dict.txt") as file:
    for line in file.readlines():     # readlines should split by '/n' for you
        (key, val) = line.split(' ')  # change delimiter to space, not default "," delimited
        dictionary[int(key)] = val  
print (dictionary)

Generally, I would recommend to use the DictReader class in the built-in 'csv' module

Answer 2

dictionary = {}

with open("dict.txt") as file:
for line in file:
    (key, val) = line.split()
    dictionary[key] = val

if you are looking to have the values as decimals you can strip off the "$" and cast it into an decimal by doing something like this

from decimal import Decimal
from re import sub

dictionary = {}

with open("dict.txt") as file:
for line in file:
    (key, val) = line.split()
    dictionary[key] = Decimal(sub(r'[^\d.]', '', val))
