Question

以下代码会生成我要删除的字符串：

with open('company_inf1.csv', 'rb') as inf :
    reader = csv.reader(inf, delimiter=',')
    reader.next() #skip header
    for i,row in enumerate(reader):
        name, date, indus, nike1, nike2, nike3, paid, abbr = row
        t = (map(str, (nike1, nike2, nike3)),) # map & merge the 3 cols together\
        b = str(t) [1:-1]
        c = b.replace('"', '\\"')
        print( name, date, indus, b , paid, abbr)

我的输出是

 ('abc', '30-06-1987', 'Service', "['nike1', 'nike2', 'nike3 '],", '100',
 'abs')

我还想删除双引号，以便输出变为：

<output missing from OP>

我已尝试使用replace和strip命令，但它对我不起作用。我还想将测试保存在我将b的值打印到测试文件中的位置。我怎么能这样做？

Answer 1

您不需要映射到字符串，因为它在文件出来时已经是一个字符串。

您可以b = [nike1, nike2, nike3]或：

with open('company_inf1.csv', 'rb') as inf :
    reader = csv.reader(inf, delimiter=',')
    reader.next() #skip header
    name, date, indus, nike1, nike2, nike3, paid, abbr = row
    print(name, date, indus, [nike1, nike2, nike3], paid, abbr)

Answer 2

To remove the parenthesis from a simple "string" you can use:

import re
...
re.sub(r'[\(\)]', '', str(mystring))

However, if it's an array, you need to employ something like:

p = re.compile(r'[\(\)]')
list = [p.sub(' ', x).strip() for x in array]

Answer 3

您可以尝试这样的事情：

print (value[0] + value[1] + "(" + value[2] + ")")
