Another way to check if a path exists (as long as you don't care if the path points to a file or directory) is to useos.path.exists. importos os.path.exists('./file.txt')# Trueos.path.exists('./link.txt')# Trueos.path.exists('./fake.txt')# Falseos.path.exists('./dir')#...
In this example, we first import theosmodule. We then define a variablefile_paththat holds the name of the file we want to check. We pass this variable to theos.path.exists()function inside anifstatement. If the file exists, it prints ‘The file exists!’, and if it doesn’t, it p...
在上面的代码中,我们定义了一个check_file_exists函数,接收两个参数:目录和文件名。函数首先合成文件的完整路径,然后使用os.path.isfile()判断文件是否存在,最后返回布尔值。 状态图 在这个过程中,我们可以将程序执行的状态用状态图表示如下: YesNoStartCheckDirectoryCheckFileFileExistsFileNotFoundEnd ...
