1. 请将replacement替换成你实际需要替换成的内容,将string替换成你实际需要进行替换的字符串。 3.4 打印替换结果 最后,我们可以使用print()函数打印替换结果。 print(result) 1. 4. 示例代码 下面是一个完整的示例代码,用于演示如何使用Python正则表达式进行替换: importre# 定义匹配模式pattern=r"apple"replacement=...

Write a Python program to add 'ing' at the end of a given string (length should be at least 3). If the given string already ends with 'ing', add 'ly' instead. If the string length of the given string is less than 3, leave it unchanged. Sample String : 'abc' Expected Result :...
If you know any Python at all, you probably know that this file defines a string and a function; the function returns whatever it is passed with string substitution and uppercase conversions applied. It's easy to use from Python: 如果你知道一点Python, 你可能知道, 这个文件定义了一个字符串与...
