通過(guò)將文本文件讀入數(shù)據(jù)框中，我想根據(jù)現(xiàn)有列中的值添加一個(gè)新列，即添加“庫(kù)存”和“交貨”中的數(shù)值。問(wèn)題是，原始數(shù)據(jù)（來(lái)自數(shù)據(jù)供應(yīng)商）是從“df.to_markdowns()”生成的?？磥?lái)我無(wú)法刪除空格。ds = pd.read_csv("C:\\TEMP\\ff.txt", sep="|", header = 0, skipinitialspace=True)ds.columns = ds.columns.str.strip()df['new'] = ds['Stock'] + ds['Delivery']print (df)對(duì)于這樣的情況，應(yīng)該采取怎樣的處理方式呢？順便說(shuō)一下，這模擬了從“df.to_markdown()”創(chuàng)建文本文件import pandas as pddata = {'Price': [59,98,79],'Stock': [53,60,60],'Delivery': [11,7,6]}df = pd.DataFrame(data)with open("C:\\TEMP\\ff.txt", 'a') as outfile:    outfile.write(df.to_markdown() + "\n")outfile.close
