Python: Convert int to binary String

We can easily convert int in Python to binary string using the built-in bin() function.

Let's take a look at a few examples.

Example 1: decimal int to binary string

decimal_number = 42
binary_str = bin(decimal_number)
print(f"Binary of {decimal_number} =  {binary_str}")

Output:
Binary of 42 = 0b101010

Example 2: hexadecimal int to binary string

hex_number = "FEFE"
binary_str = bin(int(hex_number, 16))
print(f"Binary of {hex_number}: {binary_str}")

Output:
Binary of FEFE: 0b1111111011111110
