如何找到以大寫字母開頭的字符串中的單詞？

示例輸入：

input_str = "The Persian League is the largest sport event dedicated to the deprived areas of Iran. The Persian League promotes peace and friendship. This video was captured by one of our heroes who wishes peace."

預期 output：

Persian League Iran Persian League

Answer 1

假設您也可以接受The和This ：

import re
input_string = "The Persian League is the largest sport event dedicated to the deprived areas of Iran. The Persian League promotes peace and friendship. This video was captured by one of our heroes who wishes peace."
matches = re.findall("([A-Z].+?)\W", input_string)

給

['The', 'Persian', 'League', 'Iran', 'The', 'Persian', 'League', 'This']

如果您需要忽略The和This ：

matches = re.findall("(?!The|This)([A-Z].+?)\W", input_string)

給

['Persian', 'League', 'Iran', 'Persian', 'League']

Answer 2

沒有正則表達式：

txt = "The Persian League is the largest sport event dedicated to the deprived areas of Iran. The Persian League promotes peace and friendship."

print([w for w in txt.split() if w.istitle()])

Output：

['The', 'Persian', 'League', 'Iran.', 'The', 'Persian', 'League']

如果你想跳過The詞（或任何其他詞）試試這個：

print(" ".join(w.replace(".", "") for w in txt.split() if w[0].isupper() and w not in ["The", "This"]))

Output：

Persian League Iran Persian League

Answer 3

s = """
The Persian League is the largest sport event dedicated to the deprived areas 
of Iran. The Persian League promotes peace and friendship. This video was 
captured by one of our heroes who wishes peace.
"""
print( [ x for x in s.split() if x[0].isupper() ])

Answer 4

嘗試這個：

import re
inputString = "The Persian League is the largest sport event dedicated to the deprived areas of Iran. The Persian League promotes peace and friendship."
splitted = re.split(' |\.', inputString)
result = filter(lambda x: len(x) > 0 and x[0].isupper(), splitted)
print(list(result))

結果：

['The', 'Persian', 'League', 'Iran', 'The', 'Persian', 'League']

Answer 5

另一種解決方法是使用for讀取數據並將帶有大寫字母的單詞放入列表中。

phrase = 'The Persian League is the largest sport event dedicated to the deprived areas of Iran. The Persian League promotes peace and friendship. This video was captured by one of our heroes who wishes peace.'

wordsplit = phrase.split(' ')
capitalLettersWords = []
for word in wordsplit:
    if word[0].isupper():
        capitalLettersWords.append(word)

print(capitalLettersWords)
#['The', 'Persian', 'League', 'Iran.', 'The', 'Persian', 'League', 'This']

在我的示例中，我使用了str.isupper()和str.split() ，它們都是 Python 標准庫中的內置方法。
