How to convert object to float data

This time I will bring you objectHow to convert object to float data, what are the precautions for converting object to float data, the following is a practical case, let's take a look.

DataType conversion:

I encountered a problem today, that is, the DataFrame type data is of str type Number, I want to convert the number to int or float; Baidu did not find a good one, or the keyword entered is wrong and cannot be found;

After DataFrame.info(), I found that the data are all objects

There was a previous method:

First traindata=np.array(traindata,dtype=np.float) Afterwards, I converted

traindata=pd.DataFrame(traindata)

but it looked very cumbersome, so on a whim, I tried the following method, and it was done in one sentence

traindata=pd.DataFrame(traindata,dtype=np.float); the float inside can also be replaced by int. I think other methods will work, but I haven’t tried it!

Enter DataFrame.info() to try again, all objects will become int, and you’re done!

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
