countries = {
      'AU': open('AU','r').read().splitlines(),
      'BE': open('BE','r').read().splitlines(),
      'CA': open('CA','r').read().splitlines(),
      'CH': open('CH','r').read().splitlines(),
      'CZ': open('CZ','r').read().splitlines(),
      'DE': open('DE','r').read().splitlines(),
      'ES': open('ES','r').read().splitlines(),
      'FR': open('FR','r').read().splitlines(),
      'GB': open('GB','r').read().splitlines(),
      'IE': open('IE','r').read().splitlines(),
      'IT': open('IT','r').read().splitlines(),
      'MX': open('MX','r').read().splitlines(),
      'NL': open('NL','r').read().splitlines(),

      'SG': open('SG','r').read().splitlines(),
      'US': open('US','r').read().splitlines(),   
}

companies = open('companies.txt','r').read().splitlines()
jobs = ['business+analyst','data+scientist']

for company in companies:
      for country in countries:
            for i in countries[country]:
                  for job in jobs:
                        tail = ""
                        print("using {} {}{}".format(country, company, tail))

输出

在您写的注释中，您想打印company country city job。

查看AU dict似乎有一个城市列表，然后循环for i in countries[country]:列出了城市。只需使用已有的内容即可打印company country city job：

for company in companies:
    for country in countries:
        for city in countries[country]: # i renamed to city for better readability
            for job in jobs:
                print("{} {} {} {}".format(company, country, city, job))
