We can get the Nth Word in a Given String in Python using string splitting, regular expressions, split() method, etc. Manipulating strings is a common task in programming, and extracting specific words from a string can be particularly useful in various scenarios. In this article, we will explore different methods to extract the Nth word from a given string using Python.
方法1：字符串分割
这种方法涉及将字符串分割为单词列表，并根据索引访问所需的单词。
Syntax
words = string.split()

Here, the split() method splits the string based on whitespace by default. The resulting words are stored in the words list.
算法
-
Accept the input string and the value of N.
-
使用split()方法将字符串拆分为单词列表。
-
Access the Nth word from the list using indexing.
-
Access the Nth word from the list using indexing.
Example
让我们考虑以下字符串："The quick brown fox jumps over the lazy dog." 在下面的示例中，输入字符串使用split()方法分割成一个单词列表。由于N的值为3，函数返回第三个单词，"brown"。
def get_nth_word_split(string, n):
words = string.split()
if 1
