我想逐行修改我的文件以便拥有此

17124615_01_hd.jpg  /opt/AutoPrivilege/client/photos/FRYW-1712-19774.jpg    eab516afc1aaa10ad23edb5c15ae4ea4

这是我的代码的开头：

def renameLineByLine():
    with open('/opt/data/photos.txt') as f:
        for line in f:
            newname, file, path, checksum = line.split()
            if ..?? :
                try:
                    rename(...???)
                except OSError:
                    logger.error('Got a problem')

但是我没有看到如何用新格式重命名每一行..？

Answer 1

您需要正确读入文件：跳过空行并拆分正确的值。没有path您期望的那个，并且您没有考虑最后的两个数字，这对转换至关重要。

在这里，我只是将所有新格式化的行写入新文件photos_new.txt。我希望这能让你开始。

但是请注意，您的方法名称renameLineByLine以及try/except似乎暗示您还要移动/重命名/对照片执行某些操作。如果是这种情况，这个答案是不够的，你应该试着再详细说明一下。

def renameLineByLine():
    new_lines = []
    path = '/opt/AutoPrivilege/client/photos/'
    with open('/opt/data/photos.txt', 'r') as fin, \ 
        open('/opt/data/photos_new.txt', 'w') as fout:
        for line in fin:
            if len(line) != 1:
                newname, file, checksum, no1, no2 = line.split()
                fout.write(" ".join([
                    "{}4615_{}_hd.jpg".format(no1, no2),
                    path + file, checksum, '\n'])
                )
            else:
                fout.write('\n')

Answer 2

已提供生成线条所需的所有信息。感谢@SebastianHöffner指出了明显的问题。

out = open('output.txt','w')

for line in open('data.txt'):
    if len(line) != 1:
        a, b, c, d, e = line.split()
        l = d + '4615_'+ e + '_hd.jpg /opt/AutoPrivilege/client/photos/' + b + '  '+ c     
        out.write(l + '\n')
    else:
        out.write('\n')

out.close()
