我在这方面做错了什么？

Question

[在此处输入图像描述][1]```py df['Runs'] = df['Runs'].apply(lambda x: x[0] if x[-1]=="*" else x)

It shows 'int' object is not subscriptable error in Python.

I am trying to delete the last character of the column entries and parallelly convert it into integer or float.

我不知道实际代码，因为我没有要使用的条目，但是据我所知，错误正在发生，因为您在数组中使用了 integer 类型值

根据您的操作，您可以将初始输入视为字符串，然后将其转换为 integer 用于 output
