The code searches for the substring “Gee” at a word boundary in the string “Welcome to GeeksForGeeks” and prints the start index of the match (res.start()), the end index of the match (res.end()), and the span of the match (res.span()). importre s ="Welcome to GeeksForGe...
在描述 Python 语句的形式时,我们使用斜体来标识在程序的某一点可能出现的代码类型。例如,布尔表达式表示任何评估为True或False的表达式可以跟在保留字if后,而代码块表示任何 Python 语句序列可以跟在else:后。 考虑以下程序,如果变量x的值为偶数,则打印“Even”,否则打印“Odd”: ...
The prefix is removed if the target string begins with that exact substring. If the original string doesn’t begin with prefix, then the string is returned unchanged. .removesuffix(suffix) The .removesuffix() method returns a copy of the target string with suffix removed from the end: Pytho...
