有没有更好的方法在 python 字典中找到特定值，如列表中？

Question

I have been practicing on iterating through dictionary and list in Python.

The source file is a csv document containing Country and Capital. It seems I had to go through 2 for loops for country_dict in order to produce the same print result for country_list and capital_list.

Is there a better way to do this in Python dictionary?

The code:

import csv
path = #Path_to_CSV_File
country_list=[]
capital_list=[]
country_dict={'Country':[],'Capital':[]}
with open(path, mode='r') as data:
    for line in csv.DictReader(data):
        locals().update(line)
        country_dict['Country'].append(Country)
        country_dict['Capital'].append(Capital)
        country_list.append(Country)
        capital_list.append(Capital)

i=14 #set pointer value to the 15th row in the csv document

#---------------------- Iterating through Dictionary using for loops---------------------------
if i >= (len(country_dict['Country'])-1):
    print("out of bound")

for count1, element in enumerate(country_dict['Country']):
    if count1==i:
        print('Country = ' + element)

for count2, element in enumerate(country_dict['Capital']):
    if count2==i:
        print('Capital = ' + element)
#--------------------------------Direct print for list----------------------------------------

print('Country = ' + country_list[i] + '\nCapital = ' + capital_list[i])

The output:

Country = Djibouti
Capital = Djibouti (city)
Country = Djibouti
Capital = Djibouti (city)

Answer 1

I am not sure if I get your point; Please check out the code.

import csv
path = #Path_to_CSV_File
country_dict={}
with open(path, mode='r') as data:
    lines = csv.DictReader(data)
    for idx,line in enumerate(lines):
        locals().update(line)
        country_dict[idx] = {"Country":Country,"Capital":}

i=14 #set pointer value to the 15th row in the csv document

#---------------------- Iterating through Dictionary using for loops---------------------------
country_info = country_dict.get(i)
#--------------------------------Direct print for list----------------------------------------

print('Country = ' + country_info['Country'] + '\nCapital = ' + country_info['Capital'])
