Create a 2D String Array

Question

I'm trying to create a simple 2D array of country names and capital cities. This was straightforward i Java, but I'm toiling in Python.

I'd like something along the lines of:

Scotland    Edinburgh
England    London
Wales     Cardiff

Any thoughts?

Answer 1

例如，您可以创建两个数组，一个用于首都，一个用于国家，然后通过在同一索引中访问它们的值，您可以获得首都及其国家！

capitalCities= ["Edinburgh", "London", "Cardiff"]

countries= ["Scotland", "England", "Wales"]

Answer 2

>>> arr = [['england', 'london'], ['whales', 'cardiff']]
>>> arr
[['england', 'london'], ['whales', 'cardiff']]
>>> arr[1][0]
'whales'
>>> arr.append(['scottland', 'Edinburgh'])
>>> arr
[['england', 'london'], ['whales', 'cardiff'], ['scottland', 'Edinburgh']]

You would probably be better off using a dictionary though: How to use a Python dictionary?

Answer 3

I agree with luckydog32, the dictionary should be a good solution to this.

capitolDict = {'england':'london', 'whales': 'cardiff'}
print(capitolDict.get('england'))

Answer 4

First of all, make a list of country name and their respective capital city.

countries = ['ScotLand','England','Wales']
capitals = ['Edinburgh','London','Cardiff']

Then, You can zip countries and capitals into a single list of tuple. Here, tuple is immutable sequence.

sequence = zip(countries,capitals)

Now, display:

for country, capital in sequence:
    print(country,capital)
