Python file system operations examples

Python file system operations examples

I'll respond in English this time! Here are some Python file system operations examples:

import os
os.mkdir("new_directory")

This will create a new directory named "new_directory" in the current working directory.

import os
os.rmdir("directory_to_delete")

Replace "directory_to_delete" with the actual name of the directory you want to delete. Be careful when using this method, as it permanently deletes the directory and all its contents!

open("new_file.txt", "w").write("Hello World!")

This will create a new text file named "new_file.txt" in the current working directory with the content "Hello World!".

with open("existing_file.txt", "a") as f:
f.write("Additional content!")

In this example, we're appending additional content to an existing file named "existing_file.txt".

with open("file_to_read.txt", "r") as f:
print(f.read())

This will read the contents of a file named "file_to_read.txt" and print it to the console.

import os
os.rename("old_file.txt", "new_file.txt")

Replace "old_file.txt" with the actual name of the file you want to rename, and "new_file.txt" with the desired new name.

import os
if os.path.exists("file_to_check.txt"):
print("File exists!")
else:
print("File does not exist!")

Replace "file_to_check.txt" with the actual name of the file you want to check for existence.

import os
for filename in os.listdir("directory_to_list"):
print(filename)

This will list all files and directories within the specified directory ("directory_to_list").

import shutil
shutil.copyfile("source_file.txt", "destination_file.txt")

Replace "source_file.txt" with the actual name of the file you want to copy, and "destination_file.txt" with the desired destination file name.

import os
os.rename("old_directory", "new_directory")

Replace "old_directory" with the actual name of the directory you want to move or rename, and "new_directory" with the desired new name.

These examples should give you a good starting point for performing various file system operations in Python!

Python file function

Here's a brief overview of the Python language and its functions:

Python is a high-level programming language that is easy to learn and use. It's a popular choice for beginners and experienced developers alike because it has a simple syntax, is easy to read and write, and can be used for a wide range of applications.

In terms of functions, Python has several built-in functions that you can use in your code. For example:

x = 5
print("The value of x is:", x)

my_string = "Hello, world!"
length = len(my_string)
print("The length of the string is:", length)

numbers = range(1, 6)  # generate a sequence from 1 to 5
for num in numbers:
print(num)

def square(x):
return x * x
numbers = [1, 2, 3, 4, 5]
squared_numbers = map(square, numbers)
print(squared_numbers)  # prints: [1, 4, 9, 16, 25]

def is_even(x):
return x % 2 == 0
numbers = [1, 2, 3, 4, 5]
even_numbers = filter(is_even, numbers)
print(even_numbers)  # prints: [2, 4]

numbers = [4, 1, 3, 2]
sorted_numbers = sorted(numbers)
print(sorted_numbers)  # prints: [1, 2, 3, 4]

from functools import reduce
numbers = [1, 2, 3, 4, 5]
def add(x, y):
return x + y
sum_numbers = reduce(add, numbers)
print(sum_numbers)  # prints: 15

These are just a few examples of the many functions that Python has to offer. With its wide range of built-in functions and ability to create your own custom functions, Python is a powerful language for any type of application you want to build.

Now that we've covered some of the basic concepts of Python, let's explore some more advanced topics in our next installment!
