THIS PROGRAM WILL FIND YOUR COUPLE YOU JUST NEED TO CHOOSE YOUR GENDER AND ENTER NAME

try:
    from faker import Faker
except:
    import os
    os.system("pip install faker")

fake = Faker()
F = fake.first_name_female()
M = fake.first_name_male()


enter = input('''Select your Gender!
       M:---> for Male
       F:---> for Female \t''').upper()

if "M" in enter:
    PRINCE = "Enter your name I will find your princess 💖\t"
    M = input(PRINCE).capitalize()

elif "F" in enter:
    PRINCESS = "Enter your name I will find your Prince💖\t"
    F = input(PRINCESS).capitalize()

elif input.str("M", "F") not in enter:
    print("try again")
else:
    print("wrong input")

if "M" in enter and M in couple1:
    print("Hey "+ M, couple1[M], "is your Girlfriend 💖")

if "F" in enter and F in couple:

File Positioning: 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())

Handling 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 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.")

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 ('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 image

Writing to a Binary File
Example:

with open("new_image.jpg", "wb") as file:
    file.write(binary_content)  # Writes binary content to a new file

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 ('a').

Example:

with open("output.txt", "a") as file:
    file.write("This line will be appended.\n")

Writing to a File
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() Method
The 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() Method
The 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)

Reading from a File
Python provides several methods to read the contents of a file.
read() Method
Reads 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 content

readline() Method
Reads 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 file

readlines() Method
Reads 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 list

Opening and Closing Files
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 block

Introduction to File Handling
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)

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

way to create array and perform operation using numpy.

pip install numpy

code :

import numpy as n

# creating array
d=n.array([1,2,3])
d2=n.array([4,5,6])
print(d) #it doesnt seperated with comma
print(d2) #it doesnt seperated with comma
# performing operation
print(d+d2) #it adds the corresponding elements of the arrays
print(d2-d)  #it subtracts the corresponding elements of the arrays

print(d*d2)  #it multiplies the corresponding elements of the arrays

#similary you can do operation with single element
d3=n.array([10])
print(d*d3)  
print(d+d3)
print(d-d3)

Output:-

[1 2 3]
[4 5 6]
[5 7 9]
[3 3 3]
[ 4 10 18]
[10 20 30]
[11 12 13]
[-9 -8 -7]

In these days rust is getting much popular

1) Because of it's speed of execution.
2) It's full controll on system memory
3) it's ownership model
4) And integration to other languages

So why wait let's join our rust channel
