## Unlocking the Power of Python: Printing and Converting Numbers to Binary

Python is a powerful language that is widely used in the world of programming, and one of its greatest strengths lies in its ability to manipulate numbers. Whether you’re working with integers, floats, or complex numbers, Python offers a range of tools that can help you perform a wide variety of operations with ease.

In this article, we’ll explore how to print binary representation of a number and convert an integer to binary while keeping leading zeros using Python.

## Printing Binary Representation of a Number in Python

A binary representation of a number is a way of expressing that number in terms of its base-two representation. This representation is useful in many different contexts, including computer programming and digital electronics.

And Python offers a variety of ways to print a binary representation of a number.

### Using Formatted String Literal

The first method is to use a formatted string literal. This is accomplished by placing an ‘f’ before the string and then inserting an expression inside curly braces ‘{}’.

In this expression, we can use the built-in ‘bin()’ function to convert the number to its binary representation as shown below:

``````number = 10
print(f"The binary representation of {number} is {bin(number)}")``````

Here we pass in the number 10 to the ‘bin()’ function which converts it to its binary representation ‘0b1010’, which is then inserted into the formatted string literal. Running this code will produce the following output:

``The binary representation of 10 is 0b1010``

### Using the bin() Function

The ‘bin()’ function is another method for printing the binary representation of a number. This function takes a decimal number as an argument and returns its binary equivalent in the form of a string.

### For example:

``````number = 10
print(bin(number))``````

The above code will output ‘0b1010’, which is the binary representation of 10. Keep in mind that the ‘bin()’ function always includes the prefix ‘0b’, indicating that the number is a binary representation.

### Using the hex() Function

Python also includes a built-in ‘hex()’ function which returns the hexadecimal representation of a number. The hexadecimal representation is a base-16 representation of a number, and it is useful in many different contexts.

### Here is an example:

``````number = 10
print(hex(number))``````

The above code will output ‘0xa’, which is the hexadecimal representation of 10.

## Converting an Integer to Binary and Keeping Leading Zeros

Sometimes, we need the binary representation of a number as a string, and we may want to keep leading zeros in the binary string. Here’s how we can accomplish this in Python.

### Using the format() Function

One way to convert an integer to binary and keep leading zeros is by using the format() function. Here is an example:

``````number = 10
binary_string = "{0:b}".format(number).zfill(8)
print(binary_string)``````

In this code, we first convert the number to a binary string using the format() function. The “{0:b}” part of the string is a format specifier that instructs the ‘format()’ function to convert the argument (number) to its binary representation.

We then use the ‘zfill()’ method to pad the binary string with leading zeros so that it has eight digits. Running the above code will output:

``00001010``

### Using F-strings

Another way to convert an integer to binary and keep leading zeros is by using F-strings. Here is an example:

``````number = 10
binary_string = f"{number:0>8b}"
print(binary_string)``````

In this code, we use the f-string syntax to insert the binary representation of the number into a string. The “{number:0>8b}” part of the string is a format specifier that instructs Python to convert the argument (number) to its binary representation and pad it with leading zeros so that it has eight digits.

Running the above code will output:

``00001010``

### Using the str.format() Method

Finally, we can also use the ‘str.format()’ method to convert an integer to binary and keep leading zeros. Here is an example:

``````number = 10
binary_string = "{0:0>8b}".format(number)
print(binary_string)``````

In this code, we create a string with a format specifier that instructs the ‘str.format()’ method to convert the argument (number) to its binary representation and pad it with leading zeros so that it has eight digits. Running the above code will output:

``00001010``

## Conclusion

Python is a versatile programming language that offers many ways to manipulate numbers. Printing and converting numbers to binary is just one of the many tasks that can be performed with Python.

Whether you choose to use the formatted string literal, the ‘bin()’ function, or any of the other methods we’ve covered, you can rest assured that Python has you covered when it comes to number manipulation. Python is a powerful language that offers a variety of tools to manipulate numbers.

This article explored how to print binary representation of a number and convert an integer to binary while keeping leading zeros using Python. The first method is by using a formatted string literal, while the second method is by using the ‘bin()’ function and the third is by using the ‘hex()’ function.

Moreover, we can also convert an integer to binary while keeping leading zeros by using the format() function, F-strings, and the ‘str.format()’ method. In conclusion, Python’s versatility and range of tools make it an ideal language for number manipulation tasks.
