将字符串拆分为最多2个元素的列表:txt = "apple#banana#cherry#orange" #将maxsplit参数设置为1,将返回一个包含2个元素的列表 x = txt.split("#", 1) print(x) 'apple', 'banana#cherry#orange' 参考: python 3 string split method examples python 3 split string into list...
默认情况下,.split()将在调用时进行所有可能的拆分。maxsplit但是,当您为 赋值时,只会进行给定数量的拆分。使用我们之前的示例字符串,我们可以看到maxsplit: >>> >>> s = "this is my string" >>> s.split(maxsplit=1) ['this', 'is my string'] 如上所示,如果设置maxsplit为1,则第一个空白区域...

If the string is not the valid integer value in the specified base, it will raise aValueError. You can use a try-except block to handle this error and ensure that your code runs smoothly. Theint()function is not able to convert a floating point number represented as a string into an i...
string 对象的 split() 方法只适应于非常简单的字符串分割情形,它并不允许有多个分隔符或者是分隔符周围不确定的空格。当你需要更加灵活的切割字符串的时候,最好使用re.split()方法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>line='asdf fjdk; afed, fjek,asdf, foo'>>>importre>>>re.spli...
Additionally, splittling text into lines is a very common text processing task. Therefore, Python provides a dedicated string method called.splitlines()for it, which also avoids the awkward empty string in the final index. The.splitlines()method splits a string at line boundaries, such as the...
