To return the lowest index in the string where substring sub is found, use the numpy.char.find() method in Python Numpy. The method returns the output array of ints. Returns -1 if sub is not found. The first parameter is the input array. The second parameter is the subst...
To return the string representation of a scalar dtype, use the sctype2char() method in Python Numpy. The 1st argument, if a scalar dtype, the corresponding string character is returned. If an object, sctype2char tries to infer its scalar type and then return the corresponding string ...

分别定义函数如下: def _removeSalutation(name: String) : String = { val salutationList = List("MRS", "MR", "MSTR", "MISS", "MS", "DR") for(salutation <- salutationList){ if(name.endsWith(salutation)){ return name.dropRight(salutation.length()) } } return name}val removeSalutation ...
例如: var newDocId = await DatabaseService.createTask(task); 如果要在UI中显示新文档ID,可以使用小部件树中的FutureBuilder将Future<String>展开为String。 实际调用函数时没有匹配的函数调用错误 您试图在Rectangle构造函数中默认构造两个Line(width和length)。因为Line没有默认构造函数,所以需要使用成员初始值设定...
