Question

我有两个列，我想分开，首先我摆脱任何有Jr和II的东西，哪个有效，然后我想把名字分成一个单独的标签

我有两个标签：职位编号，姓名

XXX-XXX-XXXX-XXX，＆＃34; BLOOM，DANIEL＆＃34; ,,

希望名称由2个单独列中的名字和姓氏分隔

输出3个单独的标签：

PositionNumber，LastName，FirstName

XXX-XXX-XXXX，BLOOM，DANIEL

import csv
import pandas as pd

s = open('C:\\HR employees\\Listing.csv','r').read()

chars = ('$','%','^','*','JR','II')
for c in chars:
  s = ''.join(s.split(c))
out_file = open('myfile_new.csv','w')
out_file.write(s)
out_file.close()

with open('myfile_new.csv','r') as csvfile:
    reader = csv.reader(csvfile, delimiter=',', quoting=csv.QUOTE_NONE)
    for row in reader:
        print(row)

csvfile = open('myfile2_new.csv','w')
out_file.write
out_file.close()

Answer 1

假设我有：

$ cat file.csv
PositionNumber, LastName, FirstName
XXX-XXX-XXXX, "BLOOM, DANIEL"

你可以这样做：

with open('/tmp/file.csv') as csvfile:
    r=csv.reader(csvfile)
    for row in r:
        row=[e.strip().strip('"') for e in row]
        print(row)
['PositionNumber', 'LastName', 'FirstName']
['XXX-XXX-XXXX', 'BLOOM', 'DANIEL']

csv的默认值是不加引号的。只需使用列表推导中的两个"语句处理空格和strip。

如何将csv导出为3列而不是2列？
