Integer to Binary String in Python

Last Updated : 26 Jul, 2024

We have an Integer and we need to convert the integer to binary string and print as a result. In this article, we will see how we can convert the integer into binary string using some generally used methods.

Example:

Input : 77
Output : 0b1001101
Explanation: Here, we have integer 77 which we converted into binary string

Integer to Binary String in Python

Below are some of the ways to convert Integer to Binary String in Python:

Using bin() Function,
Using format() Function,
Using bitwise Operator

Integer to Binary String Using bin() function

In this example, The variable `ans` holds the binary string representation of the integer `num` using the `bin()` function, and the result is printed, displaying "The binary string is" followed by the binary string.

Python3

num = 77  ans = bin(num)  # The binary string 'ans' is printed print(type(num)) print("The binary string is", ans) print(type(ans))

Output

<class 'int'> The binary string is 0b1001101 <class 'str'>

Integer to Binary String Using format() Function

In this example, The variable `ans` stores the binary string representation of the integer `num` using the `format()` method with the 'b' format specifier, and it is then printed with the message "The binary string is".

Python3

num = 81  ans = format(num, 'b') print(type(num)) print("The binary string is", ans) print(type(ans))

Output

<class 'int'> The binary string is 1010001 <class 'str'>

Integer to Binary String Using bitwise Operator

In this example, below code , a binary string is manually constructed by iteratively taking the remainder of the number divided by 2 and appending it to the left of the `binary_string`. The process continues until the number becomes zero. The resulting binary representation is then printed using an f-string.

Python3

# Manual conversion with bitwise operations binary_string = '' number = 42  while number > 0:     binary_string = str(number % 2) + binary_string     number //= 2  # Handle the case when num is 0 binary_result = binary_string if binary_string else '0'  # Example usage print(type(number)) print(f"The binary representation of {number} is: {binary_result}") print(type(binary_result))

Output

<class 'int'> The binary representation of 0 is: 101010 <class 'str'>
