如何获取249个国家的DataFrame？

如何解决如何获取249个国家的DataFrame？

如何在数据框中存储国家/地区名称

import pandas as pd
import pycountry

countries = pd.DataFrame()

for i in list(pycountry.countries):
    i=dict(i)
    print(i)
    countries['alpha_3'] = i['alpha_3']
    countries['name'] = i['name']
    countries['original_name'] = i['original_name']

print(countries.head())

错误 : TypeError: 'Country' 对象不可迭代

感谢提前解决！

解决方法

original_name 对象中没有属性 Country。

data = [[country.alpha_3,country.name] for country in pycountry.countries]

countries = pd.DataFrame(data,columns=['alpha_3','name'])

# print(countries.head())

  alpha_3           name
0     ABW          Aruba
1     AFG    Afghanistan
2     AGO         Angola
3     AIA       Anguilla
4     ALA  Åland Islands

你也可以像这样创建

df = pd.DataFrame([country.__dict__['_fields'] for country in pycountry.countries])

print(df.head())

  alpha_2 alpha_3           name numeric                    official_name common_name
0      AW     ABW          Aruba     533                              NaN         NaN
1      AF     AFG    Afghanistan     004  Islamic Republic of Afghanistan         NaN
2      AO     AGO         Angola     024               Republic of Angola         NaN
3      AI     AIA       Anguilla     660                              NaN         NaN
4      AX     ALA  Åland Islands     248                              NaN         NaN

然后使用 df.loc[['alpha_2','alpha_3']] 选择列。

,

pycountry.countries 中列出的所有县都没有 official_name 属性。

对于这些国家/地区，我们可以在 None 列中设置 official_name。

import pandas as pd
import pycountry

countries = pd.DataFrame()
data = []
for country in pycountry.countries:
    try:
        current = {'alpha_3': country.alpha_3,'name': country.name,'official_name': country.official_name}
    except Exception as ex:
        current = {'alpha_3': country.alpha_3,'official_name': None}        
    data.append(current)

countries = pd.DataFrame(data,columns = ['alpha_3','name','official_name'])
print(countries.head())
    

输出：

  alpha_3           name                    official_name
0     ABW          Aruba                             None
1     AFG    Afghanistan  Islamic Republic of Afghanistan
2     AGO         Angola               Republic of Angola
3     AIA       Anguilla                             None
4     ALA  Åland Islands                             None
