convert string to binary python code example

Example 1: convert int to binary python

# Python program to convert decimal to binary 
    
# Function to convert Decimal number  
# to Binary number  
def decimalToBinary(n):  
    return bin(n).replace("0b", "")  
    
# Driver code  
if __name__ == '__main__':  
    print(decimalToBinary(8))  
    print(decimalToBinary(18))  
    print(decimalToBinary(7))  
    
Output:
1000
1001

Example 2: char to binary python

>>> st = "hello world"
>>> ' '.join(format(ord(x), 'b') for x in st)
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'

#using `bytearray`
>>> ' '.join(format(x, 'b') for x in bytearray(st, 'utf-8'))
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'

Example 3: python binary string to int

>>> int('11111111', 2)
