Python-读取文件内容

 读取文件中的内容：

 

with open(\'data.txt\',\'r\') as f:
    data_list = f.readlines()#每一行是一个字符串
    data_list = [i.strip(\'\n\') for i in data_list]#去掉换行符
    data_list = [i.split(\',\') for i in data_list]#每一行以逗号分隔字符
    data = [(float(i[0]),float(i[1]),float(i[2])) for i in data_list]#将每一个字符变成float型
