Python 3.x 从维基百科获取给定类别的所有页面

我正在使用从维基百科给定类别的页面中提取所有文本

如本教程所示-

def print_categorymembers(categorymembers, level=0, max_level=2):
    for c in categorymembers.values():
        print("%s: %s (ns: %d)" % ("*" * (level + 1), c.title, c.ns))
        if c.ns == wikipediaapi.Namespace.CATEGORY and level <= max_level:
            print_categorymembers(c.categorymembers, level + 1)


cat = wiki_wiki.page("Category:Physics")
print("Category members: Category:Physics")
print_categorymembers(cat.categorymembers  

def print_categorymembers（categorymembers，level=0，max_level=2）：
对于categorymembers.values（）中的c：
打印（“%s:%s（ns:%d）”%（“*”*（级别+1），c.title，c.ns））
如果c.ns==wikipediaapi.Namespace.CATEGORY and level如果您想从页面中提取文本，则必须使用

因此，您的代码可以如下所示：

cat = wiki_wiki.page("Category:Physics")
print("Category members: Category:Physics")
for p in cat.categorymembers.values():
  if p.namespace == wikipediaapi.Namespace.CATEGORY:
    # it is category, so you have to make decision
    # if you want to fetch also text from pages that belong
    # to this category
    print(p)
  elif p.namespace == wikipediaapi.Namespace.MAIN:
    # it is page => we can get text
    print(p)
    print(p.text)

如果你想从页面中提取文本，你必须使用

因此，您的代码可以如下所示：

cat = wiki_wiki.page("Category:Physics")
print("Category members: Category:Physics")
for p in cat.categorymembers.values():
  if p.namespace == wikipediaapi.Namespace.CATEGORY:
    # it is category, so you have to make decision
    # if you want to fetch also text from pages that belong
    # to this category
    print(p)
  elif p.namespace == wikipediaapi.Namespace.MAIN:
    # it is page => we can get text
    print(p)
    print(p.text)
