Isme i option correct hai sorry for wrong code
Aap logo ko koi bhi code ho use khud se test karke dekhna chahiye
Aur agar koi code wrong lage to use batana chahiye comment me
Isse hame lagega ki aap bhi coding man se kar rhe

Python provides built-in functions to work with files. The most common operations include:
Opening a file:
open()Reading from a file:
read(), readline(), readlines()Writing to a file:
write(), writelines()Closing a file:
close()Syntax:
file = open("filename", "mode")The
mode defines how the file will be opened:'
r': Read (default mode, raises an error if the file does not exist)'
w': Write (creates a new file if it does not exist, overwrites existing content)'
a': Append (creates a new file if it does not exist, appends to existing content)'
x': Create (creates a new file, raises an error if the file exists)'
b': Binary mode (e.g., 'rb' for reading binary files)'
t': Text mode (default mode, used for reading/writing text files)Opening and Closing Files
Opening a File
To open a file, use the
Example:
This will open the file
Closing a File
It’s good practice to close a file after you are done with it using the
Alternatively, you can use the
Example:
Opening a File
To open a file, use the
open() function.Example:
file = open("example.txt", "r")This will open the file
example.txt in read mode ('r').Closing a File
It’s good practice to close a file after you are done with it using the
close() method. This frees up system resources.file.close()
Alternatively, you can use the
with statement to automatically close the file after the block of code is executed.Example:
with open("example.txt", "r") as file:
content = file.read()
print(content) # File is automatically closed after the blockReading from a File
Python provides several methods to read the contents of a file.
Reads the entire content of a file as a single string.
Example:
Reads one line at a time from the file.
Example:
Reads all lines of a file and returns them as a list of strings.
Example:
Python provides several methods to read the contents of a file.
read() MethodReads the entire content of a file as a single string.
Example:
with open("example.txt", "r") as file:
content = file.read()
print(content) # Prints the entire file contentreadline() MethodReads one line at a time from the file.
Example:
with open("example.txt", "r") as file:
line = file.readline()
print(line) # Prints the first line of the filereadlines() MethodReads all lines of a file and returns them as a list of strings.
Example:
with open("example.txt", "r") as file:
lines = file.readlines()
print(lines) # Prints all lines in a listWriting to a File
To write content to a file, you can use the
The write() method writes a string to the file.
Example:
The
Example:
To write content to a file, you can use the
write() or writelines() methods. Opening a file in write ('w') mode will create the file if it doesn’t exist or overwrite it if it does.write() MethodThe write() method writes a string to the file.
Example:
with open("output.txt", "w") as file:
file.write("Hello, World!\n")
file.write("This is a Python program.\n")writelines() MethodThe
writelines() method takes a list of strings and writes them to the file.Example:
lines = ["First line\n", "Second line\n", "Third line\n"]
with open("output.txt", "w") as file:
file.writelines(lines)

Appending to a File
When you want to add content to the end of an existing file without overwriting it, you can use the append mode ('
Example:
When you want to add content to the end of an existing file without overwriting it, you can use the append mode ('
a').Example:
with open("output.txt", "a") as file:
file.write("This line will be appended.\n")Working with Binary Files
In addition to text files, you can also work with binary files such as images, videos, and executables by opening the file in binary mode ('
Reading a Binary File
Example:
Writing to a Binary File
Example:
In addition to text files, you can also work with binary files such as images, videos, and executables by opening the file in binary mode ('
b').Reading a Binary File
Example:
with open("image.jpg", "rb") as file:
binary_content = file.read()
print(binary_content) # Outputs the binary content of the imageWriting to a Binary File
Example:
with open("new_image.jpg", "wb") as file:
file.write(binary_content) # Writes binary content to a new fileHandling File Exceptions
File operations can result in errors, such as trying to open a non-existent file in read mode. You can handle such cases using exception handling with
Example:
File operations can result in errors, such as trying to open a non-existent file in read mode. You can handle such cases using exception handling with
try and except.Example:
try:
with open("non_existent_file.txt", "r") as file:
content = file.read()
except FileNotFoundError:
print("File not found. Please check the filename.")

File Positioning:
Example:
seek() and tell()tell(): Returns the current position of the file pointer (in bytes).seek(offset, from_what): Moves the file pointer to a specified location.Example:
with open("example.txt", "r") as file:
print(file.tell()) # Prints the current position of the file pointer
file.seek(0) # Moves the pointer to the beginning of the file
print(file.read())Practice Exercises

Exclusion from the queue
The collections.deque() class is a generalization of stacks and queues, and represents a deque. A deque() supports thread-safe, memory-efficient operations for inserting and removing elements of a sequence from either side, with roughly the same O(1) performance in either direction.
