' if the file exists, 'The file does not exist.' otherwise. Python Copy 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...
This method will return True if the path points to a regular file or a symbolic link pointing to a regular file, and False otherwise. Moreover, it may also return False, if the path doesn’t exist or is a broken symbolic link. Note that from version 3.8 it returns False if the file...

print('The file does not exist.') 在上面的代码中,使用了try-except语句来捕捉如果文件不存在的FileNotFoundError异常,并在异常处理块中输出一条提示信息。如果文件存在,则会正常地读取文件并输出文件内容。 使用try-except语句可以确保程序不会因为文件不存在而崩溃,而能够更安全地处理文件读取操作。
