Python中的异常 1．语法错误语法错误也称为解析错误。例如： >>>a = 1 >>>if a == 1 print("Yes") File "<stdin>", line 1 if a == 1 print("Yes") ^ SyntaxError: invalid syntax 2．异常程序在运行时也有可能发生错误，这种在运行期间检测到的错误称为异常。例如： >>>'2' + 2 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: must be str,not int >>>1/0 Traceback (most recent call last): File "<stdin>", line 1, in <module> ZeroDivisionError: division by zero 1．TypeError 当将不同类型的数据进行运算操作时，有时会引发TypeError（不同类型间的无效操作）异常。例如： birth = input('birth:

这个错误是由于在你的代码中的第25行调用了一个名为`extract_features()`的函数，但是该函数未被定义。你需要确保该函数已经定义或已经导入到你的代码中。如果该函数已经定义，请确保它的命名和函数调用的命名相同，以及它的参数是否正确。如果你不确定如何解决该错误，请将你的代码发送给我，我会尽力帮助你解决问题。
