# import statement import os # checking file if not(os.path.exists("file.txt")): print("File does not exist") # creating & closing file fo = open("file.txt","wt") fo.close(); else: print("File exists") # checking again if os.path.exists("file.txt"): print("Now, file ...
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...
But what is the difference betweenthe is_file() and exists() methodsin Python if they check the file’s existence and return a boolean value? The main difference is that theexists()method can check the existence of both folders and files, butis_file()will only check for the file path;...
Here, I use an if statement that returns “This file exists.” if the my_file.txt file is present in my_data, and ”This file does not exist” otherwise. import os # Specify the file path file_path = 'my_data/my_file.txt' # Check if the file exists if os.path.exists(file_...
Python exists()method is used to check whether specific file or directory exists or not. It is also used to check if a path refers to any open file descriptor or not. It returns boolean value true if file exists and returns false otherwise. It is used with os module and os.path sub ...
要判断文件是否存在,可以使用os.path.exists()函数。该函数接受一个文件路径作为参数,如果文件存在则返回True,否则返回False。 下面是一个示例代码: importos file_path='example.txt'ifos.path.exists(file_path):print(f'The file{file_path}exists.')else:print(f'The file{file_path}does not exist.') ...
Does demo.txt exists TrueExample 2 In this example, we will assume that file if exists lies in the different folder.# Import os.path to use its functions import os.path # Using isfile method to check the presence of file fe=os.path.isfile("/pythondemo/demo.txt") print("Does demo....
Checking if Either Exist 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...
Use theos.path.exists()function to check if the file exists. Theos.path.exists()function returns a boolean value:Trueif the file exists,Falseif it does not exist. You can use anifstatement to handle the result: import os # Check if a file exists file_path = '/path/to/file.txt' if...
1. Using os.path.exists() This method is part of the os module and returns True if the specified file exists; otherwise, it is False. import os # Python Check if file exists if os.path.exists('filename.txt'): print("File exists") else: print("File does not exist") 2. Using pa...
