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...

' 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...
