Question

我有一个文件，我正在阅读列表。在此列表中，我需要分隔几个字段如果该行中有R，则list1应具有以下输出
所需输出为列表：

 [48998 18:45:44 qp32,   
    49005 00:44:23  qp32,
    49047 312:33:0  qp128]

如果该行中有Q，那么另一个list2应该将剩余的条目作为输出

该文件如下：

job.txt-

48998.tyrone-clustergic1_nwgsmbupi18:45:44Rqp32  
48999.tyrone-clustergic2_nwgsmbupi0Qbatch  
49005.tyrone-cluster...01R-1849-01_2mcbkss00:44:23Rqp32  
49032.tyrone-clustergaussian_top.shchemraja0Qqp32  
8788.tyrone-clusterjet_egridasevelt312:33:0Rqp128  
49052.tyrone-clustercase3sqTS1e-4mecvamsi0Qqp32  
49053.tyrone-cluster...01R-1850-01_1mcbkss0Qbatch      
49054.tyrone-cluster...01R-1850-01_2mcbkss0Qbatch          
8987.tyrone-clusterjob256icrtaraf0Qqp256          
49073.tyrone-clusterjob256icrtaraf0Qbatch

直到现在我已经尝试了

list1 = [(s.split(' ')[0]) for s in mylist if 'R' in s] #for R和类似的Q

代码

o/p :  ['48999.tyrone-clustergic2_nwgsmbupi0Qbatch', '49032.tyrone-clustergaussian_top.shchemraja0Qqp32', '49052.tyrone-clustercase3sqTS1e-4mecvamsi0Qqp32', '49053.tyrone-cluster...01R-1850-01_1mcbkss0Qbatch', '49054.tyrone-cluster...01R-1850-01_2mcbkss0Qbatch']

但输出应采用我在开头

中指定的格式

Answer 1

with open('job.txt') as f:
    list1=[]
    list2=[]
    for line in f.readlines():
        if 'R' in line:
           list1.append(line)  #you might want to format this line as per your requirements using regex
        else:
           list2.append(line)

print list1
print list2

Answer 2

job_file_handle = open("job.txt", "r") # open a handle on the file
job_lines = job_file_handle.readlines() # read in all of the lines
job_file_handle.close() # close the file handle

for line in job_lines:
    if line.split("R") > line.split("Q"): 
        processRLine(line)

    else
        processQLine(line)

从列表中提取元素
