python convert number to binary 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: python int to binary

print('{0:b}'.format(3))        # '11'
print('{0:8b}'.format(3))       # '      11'
print('{0:08b}'.format(3))      # '00000011'

def int2bin(integer, digits):
    if integer >= 0:
        return bin(integer)[2:].zfill(digits)
    else:
        return bin(2**digits + integer)[2:]
print(int2bin(3, 6))            # '000011'

Example 3: how to convert decimal to binary python

a = 5
#this prints the value of "a" in binary
print(bin(a))

Example 4: decimal to binary in python

a = 10
#this will print a in binary
bnr = bin(a).replace('0b','')
x = bnr[::-1] #this reverses an array
while len(x) < 8:
    x += '0'
bnr = x[::-1]
print(bnr)
