维基百科API。计数错误

Question

我正在使用维基百科 API 包装器来解析页面中的数据。我的 lexus_count 函数有问题。那是计数函数的输出：

The Wikipedia page for 'List of Lexus_(vehicles)' has <function lexus_count at 0x0000020B039A8268> occurrences of the word 'Lexus'"

代码如下：

import wikipedia


print ("1: Searching Wikipedia for 'List of Lexus vehicles'")
try:
    print (wikipedia.page('List of Lexus'))
    print ('-' * 60)
except wikipedia.exceptions.DisambiguationError as e:
    print (str(e))
    print ('+' * 60)
    print ('DisambiguationError: The page name is ambiguous')
print


print ("2: Searching Wikipedia for 'List of Lexus (vehicles)'")
print (wikipedia.page('List of Lexus_(vehicles)'))
print


result = wikipedia.page('List of Lexus_(vehicles)').content.encode('UTF8')
print ("3: Result of searching Wikipedia for 'List of Lexus vehicles_(vehicles)':")
print (result)
print


def lexus_count(vehicles):
    lexus_count = result.count(vehicles)
    print


print ("The Wikipedia page for 'List of Lexus_(vehicles)' has " + \
    "{} occurrences of the word 'Lexus'".format(lexus_count))
print

我的计数函数有新问题。这是错误消息：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

     30
     31 print ("The Wikipedia page for 'List of Lexus_(vehicles)' has " + \
---> 32     "{} occurrences of the word 'Lexus'".format(lexus_count()))
     33 print

TypeError: lexus_count() missing 1 required positional argument: 'lexus'

Answer 1

lexus_count 是一个函数。所以你必须调用它。

print ("The Wikipedia page for 'List of Lexus_(vehicles)' has " + \
    "{} occurrences of the word 'Lexus'".format(lexus_count()))
