Convert int to binary in Python

Python int to binary

This tutorial focuses on the different ways available to convert int to Binary in Python.

What is int in Python?

The term int is widely used in the Python programming world and is the term for the data type that is reserved for storing integer type values.

What is Binary?

It is a number system that depicts all the values using only two digits, namely 0 and 1.

How to convert int to Binary in Python?

Using standard arithmetic without a function to convert int to Binary in Python.

In this approach, we will simply make use of arithmetic operators, and convert the integer into binary as we would do on a piece of paper. In this standard approach, we need not use or create a new function to find out the binary equivalent of the integer.

The following code uses standard arithmetic without a function to convert int to Binary in Python

The above code provides the following output:

Enter a number: 5
Binary Equivalent is: 101
Explanation:
  • The number is first divided by 2 and the remainder adds up to the empty list.
  • The above step is continued until the given number is greater than zero.
  • After this, when the number is not greater than zero, reverse the list.
  • Finally, the reversed list is displayed in the output window using the print() function.

Using a user-defined function to convert int to Binary in Python.

We can create an easy user-defined function that implements the conversion of int to Binary in Python. This function is basic and is able to convert any positive integer below the number 18446744073709551615.

The following code uses a user-defined function to convert int to Binary in Python.

The above code provides the following output:

0000000000000000000000000000000000000000000000000000000000000101

Using the bin() function to convert int to Binary in Python.

Python provides an in-built bin() function that is utilized to convert int to Binary in Python.

The syntax and the working of this function are simple and easy, as it takes the integer to be converted to binary as its parameter and simply converts it into binary, and the result contains a 0b prefixed binary string.

The following code uses the bin() function to convert int to Binary in Python.

The above code provides the following output:

0b101

Using the format function to convert int to Binary in Python.

The above-mentioned bin() function displays 0b as the prefix to the converted Binary number. By using the format function, on the other hand, we can convert int to Binary and display it without the 0b prefix.

The format() function takes in two parameters, value, and format_spec. As their names dictate, the value parameter takes in the value that we want and the format_spec parameter specifies the format that is to be followed.

Some useful formatting types are mentioned below:

  • = : The sign is placed to position at the most left.
  • o : Utilized to convert the specified value to octal.
  • b : Utilized to convert the specified value to binary.
  • d : Utilized to convert the specified value to decimal.

There are many more formatting types that may come in handy, but in this case, we only need to use the b formatting type.

The following code uses the format function to convert int to Binary in Python.

The above code provides the following output:

101

Using the str.format() function to convert int to Binary in Python.

The str.format function is utilized to implement string formatting. The working and implementation of the str.format() function are quite similar to the format() function. They both even share the same format_spec parameter.

The following code uses the str.format() function to convert int to Binary in Python.

The above code provides the following output:

101

Using f-strings to convert int to Binary in Python.

f-strings are another new and improved way to implement string formatting in Python. It was introduced in Python 3.6 and can be used in any version of Python released after that.

The following code uses f-strings to convert int to Binary in Python.

The above code provides the following output:

101

That’s all about how to convert int to binary in Python.
