Question

我有一个文件＆＃34; names.txt＆＃34;。内容是

"Smith,RobJones,MikeJane,SallyPetel,Brian"

我想阅读＆＃34; names.txt＆＃34;并创建一个新文件＆＃34; names2.txt＆＃34;看起来像是：

"Rob Smith Mike Jones Sally Jane Brian Petel"

我知道我应该使用#rstrip(\n)和#.split(',')

到目前为止，我有：

namesfile = input('Enter name of file: ') #open names.txt   
openfile = open(namesfile, 'r')

Answer 1

这就是这样做的。你可能能够对它进行抛光并使其更加优雅，我鼓励你这样做：

import re

with open('names.txt') as f:
    # Split the names
    names = re.sub(r'([A-Z])(?![A-Z])',r',\1',f.read()).split(',')
    # Filter empty results
    names = [n for n in names if  n != '']
    # Swap pairs with each other
    for i in range(len(names)):
        if((i+1)%2 == 0):
            names[i], names[i-1] = names[i-1], names[i]
    print ' '.join(names)
