Python Check if File Exists: How to Check If a Directory Exists?
Python is out there ()
The exists() method of the Python programming language is what’s used to determine whether or not a particular file or directory already exists. In addition to that, it can be used to determine whether or not a path refers to any open file descriptors. If the file already exists, it will return the boolean value true; otherwise, it will return the value false. It is utilised in conjunction with the os module and the os.path sub module in the form of os.path.exists (path).
In this tutorial on using Python to determine whether a file (or directory) already exists, we will learn how to use Python to make that determination. Built-in library Python check if file exists functions are what we use when we want to determine if a file already exists in Python.
Using the functions that are listed below, you can check to see if a file or directory already exists in Python in a number of different ways.
How to Use the os.path.exists Module in Python to Determine If a File Already Exists ()
You can check very quickly to see if a file or directory exists by using the path.exists command. The following are the steps to check whether or not a file exists in Python:
How to Check If a File Exists in Python using os.path.exists()
Importing the os.path module is a necessary step that must be completed before the code can be executed.
import path from os.path, which you can do by following these steps: Step 2: Use the path.exists() function
Now, to determine whether or not a file already exists, use the path.exists() function in Python.
path.exists(“guru99.txt”)
Steps 3) Execute the code that has been provided below.
This is the final version of the code.
import path from os.path, and then import path from os.path.
def main():
print (“File exists:”+str(path.exists(‘guru99.txt’)))
print “File exists:” + str(path.exists(‘career.guru99.txt’)) if the file does not already exist.
print “directory exists:” + str(path.exists(‘myDirectory’)) if the directory already exists
if __name == “__main__”: main ()
In this instance, the only file to be produced in the working directory is named guru99.txt.
Output:
File exists: True
File exists: Existence of a false directory: false
isfile in Python ()
The isfile() method of the Python programming language is used to determine whether or not a specified path leads to an existing regular file. If the specified path leads to an existing file, it will return the boolean value true; otherwise, it will return the value false. The following syntax can be used to access it: os.path.isfile (path).
os.path.isfile()
The isfile command allows us to determine whether or not the data being read in is actually a file.
import path from os.path, and then import path from os.path.
def main():
print (“Is it File?” + str(path.isfile(‘guru99.txt’)))
print “Is it File?” followed by str(path.isfile(‘myDirectory’) if the file exists.
if __name == “__main__”: main ()
Output:
Is it in the Files? True
Is it in the Files? False
os.path.isdir()
The os.path.dir() function allows us to determine whether or not a given path leads to a directory when this is our objective.
import path from os.path, and then import path from os.path.
def main():
print “Is it Directory?” followed by str(path.isdir(‘guru99.txt’) if the file is a directory.
print “Is it Directory?” followed by str(path.isdir(‘myDirectory’)) if the directory exists.
output: main() if __name__ is the same as “__main__”
Does it contain a Directory? False
Does it contain a Directory? True
pathlibPath.exists() For Python 3.4 Python 3.4 and later versions have a module called pathlib that can be used to handle file system paths. It uses an object-oriented approach in Python to check whether or not the folder already exists.
file should be set to pathlib.Path(“guru99.txt”) if file.exists () is true: import pathlib
print (“File exist”) else: print (“File not exist”)
Output:
File exist
Complete Code
This is the final version of the code.
import os from os import path
def main():
# Print the name of the operating system using the print(os.name) # command.
Verify the existence of the item and its classification.
print(“Item exists:” + str(path.exists(“guru99.txt”))) if the item already exists.
print(“Item is a file: ” + str(path.isfile(“guru99.txt”))) if the item in question is a file.
print(“Item is a directory: ” + str(path.isdir(“guru99.txt”))) if the item in question is a directory.
if __name__ == “__main__”: main() Output:
Item is present: True Item is a document that: A directory is what True Item is: False
