Question

我有分隔文件，一部分文件只包含标题信息，如下例所示：〜＆＃34; header1.txt＆＃34;〜

的内容

a 3
b 2
c 4

〜＆＃34; header2.txt＆＃34;〜

的内容

a 4
b 3
c 5

〜＆＃34; header3.txt＆＃34;〜

的内容

a 1
b 7
c 6

另一部分是仅包含数据的文件，如下所示：

〜＆＃34; data1.txt＆＃34;〜

的内容

10 20 30 40
20 14 22 33

〜＆＃34; data2.txt＆＃34;〜

的内容

11 21 31 41
21 24 12 23

〜＆＃34; data3.txt＆＃34;〜

的内容

21 22 11 31
10 26 14 33

合并相应的数据文件后，结果与下面的示例类似：

〜＆＃34; asc1.txt＆＃34;〜

的内容

a 3
b 2
c 4

10 20 30 40
20 14 22 33

〜＆＃34; asc2.txt＆＃34;〜

的内容

a 4
b 3
c 5

11 21 31 41
21 24 12 23

〜＆＃34; asc3.txt＆＃34;〜

的内容

a 1
b 7
c 6

21 22 11 31
10 26 14 33

任何人都可以在python中给我一些帮助吗？谢谢！

Answer 1

试试这个（用python 3.4编写）。很长但应该更容易理解：

# can start by creating a function to read contents of
# each file and return the contents as a string
def readFile(file):
    contentsStr = ''
    for line in file:
        contentsStr += line
    return contentsStr

# Read all the header files header1, header2, header3
header1 = open('header1.txt','r')
header2 = open('header2.txt','r')
header3 = open('header3.txt','r')

# Read all the data files data1, data2, data3
data1 = open('data1.txt','r')
data2 = open('data2.txt','r')
data3 = open('data3.txt','r')

# Open/create output files asc1, asc2, asc3
asc1_outFile = open('asc1.txt','w')
asc2_outFile = open('asc2.txt','w')
asc3_outFile = open('asc3.txt','w')

# read contents of each header file and data file into string variabls
header1_contents = readFile(header1)
header2_contents = readFile(header2)
header3_contents = readFile(header3)

data1_contents = readFile(data1)
data2_contents = readFile(data2)
data3_contents = readFile(data3)

# Append the contents of each data file contents to its
# corresponding header file
asc1_contents = header1_contents + '\n' + data1_contents
asc2_contents = header2_contents + '\n' + data2_contents
asc3_contents = header3_contents + '\n' + data3_contents

# now write the necessary results to asc1.txt, asc2.txt, and
# asc3.txt output files respectively
asc1_outFile.write(asc1_contents)
asc2_outFile.write(asc2_contents)
asc3_outFile.write(asc3_contents)

# close the file streams
header1.close()
header2.close()
header3.close()
data1.close()
data2.close()
data3.close()
asc1_outFile.close()
asc2_outFile.close()
asc3_outFile.close()

# done!

顺便说一下，确保头文件和数据文件与python脚本在同一目录中。否则，您可以在上面的代码中相应地编辑这些文件的文件路径。输出文件asc1.txt，asc2.txt和asc3.txt将在与python源文件相同的目录中创建。

Answer 2

如果你真的想在Python中使用它，那么就可以了。

for i in range(1,4):

    h = open('header{0}.txt'.format(i),'r')
    d = open('data{0}.txt'.format(i),'r')
    a = open('asc{0}.txt'.format(i),'a')

    hdata = h.readlines()
    ddata = d.readlines()
    a.writelines(hdata+ddata)
    a.close()

当然，假设两个文件的数量都是3，并且都遵循您使用的相同命名约定。

Answer 3

如果头文件的数量等于数据文件的数量

，则此方法有效

#Glob is imported to get file names matching to the given pattern 

import glob
header=[]
data=[]

#Traversing through the file and getting the content

for files1 in glob.glob("directory/header*.txt"):
    a=open(files1,"r").read()
    header.append(a)

for files2 in glob.glob("directory/data*.txt"):
    a1=open(files2,"r").read()
    data.append(a1)

#Writng the content into the file

for i in range(1,len(data)+1):
    writer=open("directory/asc"+str(i)+".txt","w")
    writer.write(header[i-1]+"\n\n"+data[i-1])
    writer.close()

修改

此方法仅在它们位于不同文件夹中时才有效，并且该文件夹中不应包含除标题或数据文件以外的其他文件

#Glob is imported to get file names matching to the given pattern import glob header=[] data=[] #Traversing through the file and getting the content for files1 in glob.glob("directory1/*.txt"): a=open(files1,"r").read() header.append(a) for files2 in glob.glob("directory2/*.txt"): a1=open(files2,"r").read() data.append(a1) #Writng the content into the file for i in range(1,len(data)+1): writer=open("directory/asc"+str(i)+".txt","w") writer.write(header[i-1]+"\n\n"+data[i-1]) writer.close()

如何使用python将头文件与数据文件组合？
