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...
Program-check_file_exists(file_path) 在上述类图中,只有一个类Program,该类包含一个名为check_file_exists的私有方法,用于检查文件是否存在。 总结 在Python中,我们可以使用os.path.exists()方法来检查txt文件是否存在。通过这种方法,我们可以轻松地判断文件是否存在,并根据需要执行相应的操作。希望本文对你有所帮助...
Using os.path.exists() function, Using os.path.isfile() , Using the is_file() of pathlib module, Using os.path.islink() to check file exists and is a symbolic link
Checking if a File Exists This is arguably the easiest way to check if both a file existsandif it is a file. importos os.path.isfile('./file.txt')# Trueos.path.isfile('./link.txt')# Trueos.path.isfile('./fake.txt')# Falseos.path.isfile('./dir')# Falseos.path.isfile('....
