如何在python中合并列表的成员？

Question

CURRENT output:

['test1.txt StatusCode: 123', 'test2.txt StatusCode: 726', 'test1.txt CompanyID: abc']

DESIRED output:

['test1.txt StatusCode: 123 CompanyID: abc', 'test2.txt StatusCode: 726']

Answer 1

Please try the following code. It works for your sample.

current_output = ['test1.txt StatusCode: 123', 'test2.txt StatusCode: 726', 'test1.txt CompanyID: abc']
d = dict()
order = []
for item in current_output:
    k,v = item.split(' ', 1)
    if k not in order:
        order.append(k)
    d[k] = d.get(k, []) + [v]
desired_output = ["%s %s" % (k, ' '.join(d[k])) for k in order]
print desired_output

Answer 2

也许您可以获得列表的最后一个元素，将其拆分，然后将其附加到其他字符串元素
