Answer 1

我写过这篇文章让你开始。它读取第一个文件'input.txt'，然后将指定数量的行写入新文件'new.txt'。

lines_to_write = 5 #amount of lines to write from old file to new

with open('input.txt') as f:
    data = f.readlines()

with open('new.txt', 'w') as f:
    for x in range(lines_to_write):
        f.write(data[x])

这显示了如何操作文件，应该是你开始的良好基础。

Answer 2

您似乎希望将可变数量的行写入一行。所以，我编写了一个列表理解，它将组合可变数量的行。

with open("in.txt","r") as fi, open("out.txt","w") as fo:
    li = fi.readlines()
    inBetween = 2
    fo.write("\n".join(" ".join(line.strip() for line in li[i:i+inBetween]) for i in range(0,len(li),inBetween)))

每隔一行：

for x in xrange(len(v.splitlines())):
    if x%2 == 0:
        print " ".join(v.splitlines()[x:x+2])

每三行：

for x in xrange(len(v.splitlines())):
    if x%3 == 0:
        print " ".join(v.splitlines()[x:x+3]

更短的：

[ " ".join(v.splitlines()[x:x+2]) for x in xrange(len(v.splitlines())) if x%2 == 0 ]
[ " ".join(v.splitlines()[x:x+3]) for x in xrange(len(v.splitlines())) if x%3 == 0 ]

依旧......
