What Is the split() Function in Python and What Does It Do? The split() function in Python operates on strings. It takes a string as input and splits it wherever it encounters a “separator” (a character that acts as a marker for the split). The output is a list of strings, wher...
该return语句返回一个函数的值。 return没有表达式参数返回None。从函数的末尾掉落也会返回None。 该语句result.append(a)调用list对象 的方法result。方法是“属于”对象并被命名的函数 obj.methodname,其中obj是某个对象(可能是表达式),并且methodname是由对象的类型定义的方法的名称。不同类型定义不同的方法。不同...
You will only get this error in your Python program when you apply the split attribute(property or method) on a list object. Many Python learners who are new to programming do not have a complete idea about the return values, and sometimes they simply apply the method to the wrong data ...
