Question

我有两个文件

File1中：

IdName1 Info1 Info2 Info3   #Info: from program1 for name1  #Info: from program2 for name1
IdName2 Info1 Info2 Info3   #Info: from program1 for name2  #Info: from program2 for name2
IdName4 Info1 Info2 Info3   #Info: from program1 for name4  
IdName3 Info1 Info2 Info3   #Info: from program1 for name3  #Info: from program2 for name3

文件2：

# ProgramInfo
# Query: IdName1 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
line1
line2
# ProgramInfo
# Query: IdName2 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
# ProgramInfo
# Query: IdName4 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
line1
line2
line3
line4

现在我需要在“#Query：”之后检查“IdName1 Info1 Info2 Info3”是否在File2中，如果是，我需要从File1中的那一行拆分iformation 在相应的“＃ProgramInfo”行之前将其插入File2。输出文件应如下所示：

OUTPUTFILE：

# IdName1 Info1 Info2 Info3
# Info: from program1 for name1 
# Info: from program2 for name1
# ProgramInfo
# Query: IdName1 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
line1
line2
# IdName2 Info1 Info2 Info3 
# Info: from program1 for name2 
# Info: from program2 for name2
# ProgramInfo
# Query: IdName2 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
# IdName4 Info1 Info2 Info3 
# Info: from program1 for name4 
# ProgramInfo
# Query: IdName4 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
line1
line2
line3
line4

我现在的问题是，如何将相应的三行添加到File2中，我一直在尝试这样的事情：

import sys
def programs_info_comb(fileName1, fileName2):
    my_file1 = open(fileName1, "r")
    my_line1=my_file1.readlines()
    my_file2 = open(fileName2, "r")
    my_line2=my_file2.readlines() 
    for line1 in my_line1: 
        (name1, info1, info2)= line1.strip().split("\t")
        for line2 in my_line2:
            if line2.startswith("# Q"):
                name2 = line2[9:-1]
                if name1 == name2:
                    #### here Im lost how to tell where I want those next two lines to be printed
                    print "#"+" "+name1
                    print info1
                    print info2
    my_file1.close
    my_file2.close
if __name__== "__main__":
    programs_info_comb(sys.argv[1], sys.argv[2])

可能有一个更简单的方法，所有的帮助将被感激地接受感谢您的时间 Daeja

Answer 1

可能有更好的方法可以做到这一点，但这是一种有效的方法：

def programs_info_comb(f1, f2):
    tmp = open(f1, "r")
    file1 = tmp.readlines()
    tmp.close()

    tmp = open(f2, "r")
    file2 = tmp.readlines()
    tmp.close()

    for line in file1:
        content = line.split("#")[0].strip()
        for i, line in enumerate(file2.copy()):
            if line == "# Query: %s\n" %content:
                file2.insert(i-1, "# %s\n" %content)
                break

    tmp = open("output.txt", "w")
    tmp.writelines(file2)
    tmp.close()

您还应该查看评论部分中提到的数据库。

在某些情况下，也可以避免使用两个嵌套的for循环。但是，这是一种完全有效的方式，可以满足您的要求。

import sys
def programs_info_comb(fileName1, fileName2):
    my_file1 = open(fileName1, "r")
    my_line1=my_file1.readlines()
    my_file1.close()

    my_file2 = open(fileName2, "r")
    my_line2=my_file2.readlines() 
    my_file2.close()

    # load file1 into a dict for lookup later
    infoFor = dict()
    for line1 in my_line1: 
        parts = line1.strip().split("\t")
        infoFor[parts[0]] = parts[1:] 

    # iterate over line numbers to be able to refer previous line numbers
    for line2 in range(len(my_line2)):
        if my_line2[line2].startswith("# Q"):
            name2 = my_line2[line2][9:-1]
            # lookup
            if infoFor.has_key(name2):
                print '# ' + name2
        for info in infoFor[name2]:
                    print info
            # print programinfo and query lines
                print my_line2[line2-1],
                print my_line2[line2],
    # skip program info always
        elif my_line2[line2].startswith("# ProgramInfo"):
            pass
    # otherwise just print as is
        else:
            print my_line2[line2],

if __name__== "__main__":
    programs_info_comb(sys.argv[1], sys.argv[2])

我已将file1加载到字典中以便稍后查找并将输出发送到stdout。在发送输出之前，我已经检查了我所在的线路类型并相应地输出。

这是o / p： -

C:\>python st.py f1.txt f2.txt
# IdName1 Info1 Info2 Info3
#Info: from program1 for name1
#Info: from program2 for name1
# ProgramInfo
# Query: IdName1 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
line1
line2
# IdName2 Info1 Info2 Info3
#Info: from program1 for name2
#Info: from program2 for name2
# ProgramInfo
# Query: IdName2 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
# IdName4 Info1 Info2 Info3
#Info: from program1 for name4
# ProgramInfo
# Query: IdName4 Info1 Info2 Info3
# DatabaseInfo
# FiledInfo
