在使用Docker进行容器化部署时,有时会遇到容器启动失败的情况,其中一个常见的问题是容器中缺少所需的软件或文件。本文将帮助解决一个具体的问题,即当容器启动失败并出现日志提示"File does not exist:没有python"时,该如何解决。 问题分析 首先,我们需要明确问题的原因。当容器启动失败并提示"File does not exist:...
首先,我们导入了Python的os模块。 然后,我们定义了一个名为check_file_exists的函数,该函数接受一个文件路径作为参数。 在函数中,我们使用os.path.exists函数来判断文件是否存在。如果文件存在,则打印"File exists.“,否则打印"File does not exist.” 最后,我们进行了一个简单的测试,检查文件名为"test.txt"的文...
if not os.path.isfile(file_path_real): logging.error("File does not exist.") return None, None try: tree = etree.parse(file_path_real) # Obtain the root node. root = tree.getroot() except Exception as reason: logging.error(reason) raise for lic in root: for child in lic: if ...
If you don’t want to raise an Exception, or you don’t even need to open a file and just need to check if it exists, you have different options. The first way is using the different methods inos.path: os.path.isfile(path): returns True if the path is a valid file ...
Again, just likeisfile,os.path.isdirdoes follow symlinks. It is also just a simple wrapper aroundos.statandstat.S_ISDIR(mode), so you're not getting much more than convenience from it. Checking if Either Exist Another way to check if a path exists (as long as you don't care if the...

Now we will define a basic check whether either file does exist using theis_file()method. We will define the next block to check whether a file is empty using thegetsize()function from theosmodule. frompathlibimportPathimportosdefIf_TextFileEmpty():my_file=Path(r"C:\Users\Dell\Desktop\...
Does demo.txt exists True Example 2In this example, we will assume that file if exists lies in the different folder from python script. # Import Path from pathlib module from pathlib import Path # Check if file exist path = Path("/pythondemo/Demo.txt") ...
