bin() to convet integer to binary string in python

bin(number)

number :input number in decimal
Return the binary number as string.

Examples

num=5
print(bin(num)) # 0b101

num=47
print(bin(num)) # 0b101111

In our binary output, 0b is always prefixed. As the output is a string we can remove it like this

num=47
num1=bin(num)
print(num1[2:]) # 101111

Without using bin() and by using format()

num=47
print(format(num,'b')) # 101111

Example 1: Convert Negative Integers to Binary

print(bin(-10)) # Output: '-0b1010'

Example 2: Binary Conversion for Data Encoding

data = [65, 66, 67]
binary_data = [bin(x) for x in data]
print(binary_data)  # Output: ['0b1000001', '0b1000010', '0b1000011']

Example 3: Converting Large Numbers to Binary

large_num = 1024
print(bin(large_num))  
# Output: '0b10000000000'

Example 4: Removing the '0b' Prefix from the Binary String

num = 15
binary_str = bin(num)[2:]  
print(binary_str)  
# Output: '1111'

Example 5: Binary Addition

num1 = 0b1010  # Binary for 10
num2 = 0b1100  # Binary for 12
result = num1 + num2

print(bin(result))  
# Output: '0b10110' (binary for 22)

print(int(result))  
# Output: 22
