count=pd.DataFrame(test_data_1['SoilType'].value_counts())print(count) 得到结果如下。 好的,没有问题:可以看到此结果共有63行,也就是'SoilType'列原本是有63个不同的值的,证明我们的独热编码没有出错。 此时看一下我们的test_data_1数据目前长什么样子。 代码语言:javascript ...
python读写txt文件 re>文件的打开的两种方式 f = open("data.txt","r") #设置文件对象 f.close() #关闭文件 #为了方便,避免忘记close掉这个文件对象,可以用下面这种方式替代 with open('data.txt',"r") as f: #设置文件对象 str = f.read() #可以是随便对文件的操作 一、读文件 1.简单的将文件读...
One hot encoding represents the categorical data in the form of binary vectors. Now, a question may arise in your minds, that when it represents the categories in a binary vector format, then when does it get the data converted into 0’s and 1’s i.e. integers? Well, in one hot enc...
xlsx python encoding编码格式 在Python中处理.xlsx文件时,通常使用openpyxl或pandas库。这两个库都支持处理xlsx文件,并且可以指定编码格式。 在使用openpyxl库时,可以按以下方式指定编码格式: pythonfrom openpyxl import load_workbook wb = load_workbook(filename='your_file.xlsx', read_only=True, data_only=...
$ python3 codecs_encode_error.py strict ERROR: 'ascii' codec can't encode character '\xe7' in position 4: ordinal not in range(128) Some of the other error modes are more flexible. For example, replace ensures that no error is raised, at the expense of possibly losing data that ca...
