os.path.isfile('main.txt') checks whether a file named 'main.txt' exists in the current directory and returns True if it does and False if it does not. os.path.isfile('main.py') checks whether a file named 'main
Another cleaner approach can be to read the file and handleFileNotFoundErrorto know if the file existed when we accessed it. try:withopen(filepath)asf_obj:contents=f_obj.read()print(contents)exceptFileNotFoundError:msg="Sorry, the file "+filepath+"does not exist."print(msg) 4. Conclusio...
' 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...

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...
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"的文件是否存在。
Example 1 In this example, we will assume that file if exists lies in the same folder as python script. python # Import Path from pathlib module from pathlib import Path # Check if file exist path = Path("Demo.txt") print("Does demo.txt exists ?",path.is_file()) Output bash Does...

pathlib模块在Python3版本中是内建模块,但是在Python2中是需要单独安装三方模块。 使用pathlib需要先使用文件路径来创建path对象。此路径可以是文件名或目录路径。 检查路径是否存在 path = pathlib.Path("path/file") path.exist() 检查路径是否是文件 path = pathlib.Path("path/file") path.is_file()...
