python遍历列表列表

Question

我有:

master_list = [['001', '15\n', '963789', '40\n', '741239', '80\n', '985697', '80\n', '854698', '35\n', '965874', '10\n'],
 ['002', '25\n', '326574', '65\n', '944223', '40\n', '312689', '45\n', '225869', '80\n', '789654', '35\n'],
 ['003', '10\n', '857963', '50\n', '253698', '40\n', '965478', '50\n', '186458', '40\n', '351296', '40\n'],
 ['004', '20\n', '675964', '40\n', '612985', '40\n', '653674', '35\n', '957296', '50\n', '852169', '40\n'],
 ['005', '13', '246912', '40\n', '371956', '40\n', '819736', '40\n', '915745', '50\n', '197548', '40']]

内部列表的前两项是 id 和 pay rate。如 master[0][0], master[0][1]

然后我有:

for row in master_list:
        emp_id = row.pop(0)# extracts the employee id
        hourly_rate = row.pop(0)# extracts the hourly rate

行然后变成这样:['963789', '40\n', '741239', '80\n', '985697', '80\n', '854698', '35\n', '965874', '10\n']

此行中的第一项是工作编号，第二项是工作时间。第三项是工作编号，第四项是工作时间等，直到列表结束...

我将如何迭代此列表以打印如下内容:

Job Number: 963789
Employee ID: 001
Hours Worker: 40
Hourly Rate: 15

Job Number: 741239
Employee ID: 001
Hours Worker: 80
Hourly Rate: 15

等...

Answer 1

对于每一行，您都可以像这样访问数据

job_number = row[::2]
hours_worked = row[1::2]

要打印，只需做这样的事情

for row in master_list:
    emp_id = row.pop(0)# extracts the employee id
    hourly_rate = row.pop(0)# extracts the hourly rate
    job_number = row[::2]
    hours_worked = row[1::2]
    for i in range(len(job_number)):
        print "Job Number: {jn}\nEmployee ID: {eid}\nHours Worked: {hrw}\nHourly Rate: {hrr}\n".format(jn=rob_number[i], eid=emp_id, hrw=hours_worked[i], hrr=hourly_rate)
