英文:
Doing Apply(str) to int creates a bunch of \n's?
问题
我有一个类似这样按年份标记的数据框：
我想把这些ints更改为strs，因为它们实际上是分类变量。然而，这是结果：
X_train['YrSold'] = X_train['YrSold'].apply(str)
我更希望在.apply(str)过程中自动去掉所有这些\n，而不是通过正则表达式后处理每一列。似乎后者会更容易出错。
英文:
I have a dataframe like this labeled by year:
I would like to change these ints to strs because they are actually categorical variables. However, this is the result:
X_train['YrSold'] = X_train['YrSold'].apply(str)
I would prefer to get rid of all those \n's automatically in the .apply(str) process, as opposed to postprocessing each column via regex. Seems like the latter would have more room for error.
