例如,我们可以使用check_file来检查文件是否是文本文件: importcheck_file# 检查文件是否是文本文件ifcheck_file.is_text_file("example.txt"):print("文件是文本文件")else:print("文件不是文本文件") 1. 2. 3. 4. 5. 6. 7. 上述代码中,我们使用is_text_file函数来判断文件是否是文本文件。如果是文本文...
If you plan on using files in your Python script, you will likely want to check whether the file exists before performing any file operations. Luckily, checking if a file exists is straightforward in Python, thanks to thepathlibandosmodules. You can use Python to open, read, write, and cl...
In Python, we can use theos.pathandpathlibmodules to check if a file exists at the specified path. Thepathlibhas been available since Python 3.4, and provides an object-oriented way of accessing the file or directory paths. In older versions, use theos.pathmodule. Quick Reference importos.pat...
1. [Python.Docs]: os.path.exists(path) Also check other function family members like os.path.isfile, os.path.isdir, os.path.lexists for slightly different behaviors: Return True if path refers to an existing path or an open file descriptor. Returns False for broken symbolic links. On so...
If all you care about is the current process, an easy way is to use the file object attribute "closed" f = open('file.py') if f.closed: print 'file is closed' This will not detect if the file is open by other processes! source: http://docs.python.org/2.4/lib/bltin-file-obj...
if my_file.is_file(): print("The file exists") else: print("The file does not exist") Note that in Python you can create an empty file with the command with open(filename.txt, 'w'). For example: import os if not os.path.isfile('myfile.txt'): with open('myfile....

solve a problem in programming, and this holds true especially inPython. Many times you'll find that multiple built-in or standard modules serve essentially the same purpose, but with slightly varying functionality. Checking if a file or directory exists using Python is definitely one of those ...

Once again, welcome back to another issue of the How to Python series. Today, we’re going to learn how to check if a list is empty in Python.In short, the best way to check if a list is empty is to take advantage of that list’s type flexibility. For example, the statement ...
