因为字符串实现了__add__(self, other)方法，所以可以使用+添加两个字符串。小小白：主要是为了确保St...
在上面的示例中,我们使用%s来指定字符串的位置,并在两个字符串之间添加空格。 方法三:使用字符串的join方法 除了上述两种方法外,我们还可以使用字符串的join方法来实现。在Python中,字符串的join方法可以将一个字符串列表(或可迭代对象)中的所有元素连接起来,并使用指定的分隔符进行分隔。那么,我们只需要将两个字符...
3. Transforming Strings There are a bunch of fun methods for transforming our string text. Among those that are more important to understand to make real-world applications we can find thelower(),upper(), strip(), count()andjoin()methods. Thestrip()method is useful when dealing with user ...
In Python, we can join (concatenate) two or more strings using the+operator. greet ="Hello, "name ="Jack"# using + operatorresult = greet + nameprint(result)# Output: Hello, Jack Run Code In the above example, we have used the+operator to join two strings:greetandname. ...
join(valid_answers)}") user_answer = input(f"\n{question} ") This works but has an unfortunate repetition of two identical input() lines. It’s necessary to get at least one answer from the user before checking whether it’s valid or not. You then have a second call to input() ...

print(' '.join(pigLatin)) 这个循环结束后,我们通过调用join()方法将字符串列表合并成一个字符串。这个字符串被传递给print()以在屏幕上显示我们的猪拉丁。 你可以在找到其他简短的基于文本的 Python 程序,比如这个。 总结 文本是一种常见的数据形式,Python 附带了许多有用的字符串方法来处理存储在字符串值中的...
