一、pd.read_csv() 从文件、url或文件型对象读取分割好的数据,英文逗号是默认分隔符 path=r"F:\课程资料\Python机器学习\聚类\31省市居民家庭消费水平-city.txt" df1=pd.read_csv(path,header=None,encoding='GB18030') df1.head() 参数说明:
excel_filename ='数据.xlsx' df = pd.read_excel(excel_filename) # 方法二:把日期中的分秒替换为0 SampleTime_new = df['SampleTime'].map(lambda x: x.replace(minute=0, second=0)) data = df[SampleTime_new.duplicated() == False]
