How to Convert an Integer to Binary in Python

In programming languages like Python, numbers are represented in many different formats, like decimal, binary, hexadecimal, and octal.

Sometimes, you need to convert a number from one format to another.

In this post, we'll learn how to convert an integer to binary in Python.

Using bin()

To convert an integer to binary in Python, you can use the built-in function for that, bin().

Just pass in the integer you want to convert to binary and it will return a string with the binary representation of that number.

Let's give it a try using the number 10:

PYTHON
integer = 10
binary = bin(integer)

print(binary)

BASH
0b1010

Using format()

Another way to convert an integer to binary is to use the format() method.

This method does the same thing as bin() but will remove the prefix 0b from the string.

PYTHON
integer = 10
binary = format(integer, "b")

print(binary)

BASH
1010

This function can format the number in many other formats if you want, but we're showing you the binary format here since that's what the post is about.

Conclusion

In this post, we learned how to format an integer to binary in Python.

You have two main ways, either using the bin() function or the format() method.

The only main difference is that bin() will return a string with the prefix 0b while the format() method will remove the prefix 0b.
