使用python从文本文件中提取路径

Question

我有一个巨大的文本文件，其中包含不同的路径。 我必须提取包含.o文件的路径。 我正在这样做，但是第一条路径没有被提取。 我需要制作一个通用代码来提取这种类型的文件，文件如下所示

输出：C：\\ 00_SIVA \\ TRW \\ SANDBOX \\ DAIMLER_MRAV3_V1.1149 \\ MainMicro \\ Application \\ SafeTLib \\ SBST \\ SBST_Kernel_ISG.o

C：\\ 00_SIVA \\ TRW \\ SANDBOX \\ DAIMLER_MRAV3_V1.1149 \\ MainMicro \\ Application \\ SafeTLib \\ SBST \\ SBST_Kernel_TestCode.o

C：\\ 00_SIVA \\ TRW \\ SANDBOX \\ DAIMLER_MRAV3_V1.1149 \\ MainMicro \\ Application \\ SafeTLib \\ SBST \\ SBST_TC16P_ISG.o

但是输出缺少第一条路径，即C：\\ 00_SIVA \\ TRW \\ SANDBOX \\ DAIMLER_MRAV3_V1.1149 \\ MainMicro \\ Application \\ SafeTLib \\ SBST \\ SBST_Kernel_CoreTest.o

假设路径可以在任何地方，但用空格隔开，换句话说：

with open("test.txt") as f:
    for line in f:
        for word in line.split(" "):
            if re.search("^.*\.o$", word):
                print (word.strip())
