Question

我所追求的是使用python来提取与csv的自由文本字段中出现的正则表达式的匹配。如果找到匹配（或匹配），我希望脚本将这些匹配附加到csv中的新列中。

示例csv数据：

recordID,freetextField

row1,lots of text blah blah blah etc 07635463726 etc etc etc

row2,07938998988 blahblah

row3,07635463726blahblah07635463726

期望的结果：

recordID,freetextField,phonenumber1,phonenumber2

row1,lots of text blah blah blah etc 07635463726 etc etc etc,07635463726,

row2,07938998988 blahblah,07938998988

row3,07635463999blahblah07635463726,07635463999,07635463726

使用正则表达式：

(?(?:(?:0(?:0|11)\)?[\s-]?\(?|\+)44\)?[\s-]?\(?(?:0\)?[\s-]?\(?)?|0)(?:\d{5}\)?[\s-]?\d{4,5}|\d{4}\)?[\s-]?(?:\d{5}|\d{3}[\s-]?\d{3})|\d{3}\)?[\s-]?\d{3}[\s-]?\d{3,4}|\d{2}\)?[\s-]?\d{4}[\s-]?\d{4}|8(?:00[\s-]?11[\s-]?11|45[\s-]?46[\s-]?4\d))(?:(?:[\s-]?(?:x|ext\.?\s?|\#)\d+)?)

你可以尝试类似的东西：

outrow = []    
with open("path/to/inputFile.csv", "rb") as fileIn:#input file location
    with open("path/to/outputFile.csv", "wb") as fileOut:#output file location
        writer = csv.writer(fileOut)
        reader = csv.reader(fileIn, delimiter = ',')
        for row in reader:
            recordID = row[0]
            freetextField = row[1]
            phonenumber1 = ''
            phonenumber2 = ''
            for cell in row:
                phonenumber2 = re.findall(r"regex/goes/here",cell)
                outrow
        writer.writerow(["recordID,freetextField,phonenumber1,phonenumber2"])   
        writer.writerow([recordID,freetextField,phonenumber1,phonenumber2])

从csv中找到正则表达式匹配项并附加为新列
