Python]将两个文本文件合并为一个（逐行）

我是python新手。我要做的是将文件“a”和文件“b”逐行组合成一个文件

比如说,

文本文件a=a（“\n”）b（“\n”）c

text file b = 1("\n")2("\n") 3

新文本文件将包含

a1（“\n”）b2（\n”）c3

def main():
  f1 = open("aaa.txt")
  f2 = f1.readlines()
  g1 = open("bbb.txt")
  g2 = g1.readlines()
  h1 = f2+g2
  print(h1)

---

很抱歉，这是我第一次使用stackoverflow..

阅读有关文件处理和高效使用内置函数的更多信息。 对于您的查询，仅使用

h1=f2+g2

是不合适的

a=open('a.txt','r').readlines()
b=open('b.txt','r').readlines()
with open('z.txt','w') as out:
    for i in range(0,10): #this is for just denoting the lines to join.
         print>>out,a[i].rstrip(),b[i]

---

要点：

combine =[]

with open("x.txt") as xh:
  with open('y.txt') as yh:
    with open("z.txt","w") as zh:
      #Read first file
      xlines = xh.readlines()
      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists
      #combine = list(zip(ylines,xlines))
      #Write to third file
      for i in range(len(xlines)):
        line = ylines[i].strip() + ' ' + xlines[i]
        zh.write(line)

1

a
b
c

a 1
b 2
c 3

with open("x.txt") as xh:
  with open('y.txt') as yh:
    with open("z.txt","w") as zh:
      #Read first file
      xlines = xh.readlines()
      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists  and Write to third file
      for line1, line2 in zip(ylines, xlines):
        zh.write("{} {}\n".format(line1.rstrip(), line2.rstrip()))

• 使用

  和

  打开文件。不需要关闭文件
• 使用

  zip

  函数组合两个列表

不带zip且内嵌注释的代码：

combine =[]

with open("x.txt") as xh:
  with open('y.txt') as yh:
    with open("z.txt","w") as zh:
      #Read first file
      xlines = xh.readlines()
      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists
      #combine = list(zip(ylines,xlines))
      #Write to third file
      for i in range(len(xlines)):
        line = ylines[i].strip() + ' ' + xlines[i]
        zh.write(line)

      xlines = xh.readlines()
      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists  and Write to third file
      for line1, line2 in zip(ylines, xlines):
        zh.write("{} {}\n".format(line1.rstrip(), line2.rstrip()))

x.txt的内容：

combine =[]

with open("x.txt") as xh:
  with open('y.txt') as yh:
    with open("z.txt","w") as zh:
      #Read first file

      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists
      #combine = list(zip(ylines,xlines))
      #Write to third file
      for i in range(len(xlines)):
        line = ylines[i].strip() + ' ' + xlines[i]
        zh.write(line)

      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists  and Write to third file
      for line1, line2 in zip(ylines, xlines):

      #Write to third file
      for i in range(len(xlines)):
        line = ylines[i].strip() + ' ' + xlines[i]
        zh.write(line)

      for line1, line2 in zip(ylines, xlines):

带有zip函数的代码：

combine =[]

with open("x.txt") as xh:
  with open('y.txt') as yh:
    with open("z.txt","w") as zh:
      #Read first file
      xlines = xh.readlines()

      ylines = yh.readlines()
      #Combine content of both lists
      #combine = list(zip(ylines,xlines))
      #Write to third file
      for i in range(len(xlines)):
        line = ylines[i].strip() + ' ' + xlines[i]
        zh.write(line)

      #Read second file
      ylines = yh.readlines()
      #Combine content of both lists  and Write to third file

您尝试了什么？谢谢您的回复。我尝试了很多不同的东西，也许你会嘲笑我：（我想出了如何制作一个（“\n”）b（“\n”）c（“\n”）1（“\n”）2（“\n”）3），但我在谷歌上找不到任何地方（一行一行）：（欢迎使用StackOverFlow user6886108！！！请查看此链接-至少向我们展示打开两个文件并打印的代码Linessory伙计们这是我第一次问有关Stackflow的问题，感谢你提供的链接Dinesh。哇..你让我开心了一天。我从昨天开始就一直在处理此问题。要根据你所做的内容编写新文件，请告诉我们我知道我应该从newfile=open（“new”，“w”）开始，如果行数超过10行怎么办？@user6886108@Dinesh而不是10行，你可以使用行数最少的文件a或文件b的len。当你使用的行数比另一行多的文件时。这行（

print a[I].rstrip（），b[I]

）将抛出错误。@user6886108修改了代码，将其作为

z.txt

存储在单独的文件中。谢谢。如果我想使z.txt成为1（“\n”）b2（“\n”）c3（“\n”）？而不是（“\n”）1（“\n”）b（“\n”）2（“\n”）c（“\n”）3检查更新后的代码永远不知道“使用打开文件。无需关闭文件”谢谢！这对我很有帮助much@DineshPundkar很高兴看到您编辑的代码，范围而不是组合。捕捉得很好。
