import os
from os import stat
from pwd import getpwuid

searchFolder = raw_input("Type in the directory you wish to search e.g \n /Users/bubble/Desktop/ \n\n\n")
resultsTxtLocation = raw_input("FIBS saves the results in a txt file. Where would you like to save results.txt? \nMust look like this: /users/bubble/desktop/workfile.txt \n\n\n") 

with open(resultsTxtLocation,'w') as f:
    f.write('You searched the following directory: \n' + searchFolder + '\n\n\n')
    f.write('Results for custom search: \n\n\n')
        for root, dirs, files in os.walk(searchFolder):
            for file in files:
                    pathName = os.path.join(root,file)
                    print pathName
                    print os.path.getsize(pathName)
                    print
                    print stat(searchFolder).st_uid
                    print getpwuid(stat(searchFolder).st_uid).pw_name
                    f.write('UID: \n'.format(stat(searchFolder).st_uid))
                    f.write('{}\n'.format(pathName))
                    f.write('Size in Bytes: {}\n\n'.format(os.path.getsize(pathName)))

我遇到这条线路有问题:

f.write('UID: \n'.format(stat(searchFolder).st_uid))

我不知道'{} \ n'.format是做什么的,但是有人在之前的问题中提出过这个问题,所以我认为它在这里工作,但事实并非如此。

在输出文本文件中,我得到以下内容:

UID: / Users / bubble / Desktop / Plot 2.docx 字节大小:110549

但它应该说:UID:501

如何让f.write理解两个参数并将其写入txt文件?

非常感谢

变化

f.write('UID: \n'.format(stat(searchFolder).st_uid))
f.write('{}\n'.format(pathName))
f.write('Size in Bytes: {}\n\n'.format(os.path.getsize(pathName)))

f.write('UID: {0}\n'.format(stat(searchFolder).st_uid))
f.write('{0}\n'.format(pathName))
f.write('Size in Bytes: {0}\n\n'.format(os.path.getsize(pathName)))

Look at this answerpython documentation以了解字符串格式。

'UID: {}\n'.format(stat(searchFolder).st_uid)。如果没有{},则只返回{}: \n

这是字符串格式。 {}代表替换字段。您可以阅读doc
