how to convert number to binary in 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: how to convert decimal to binary python

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

Example 3: 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)

Example 4: how to get the binary value in python

bin(19) # will return '0b10011'

#or you can do

def binary(num):
    array = []

    #makes the binary value
    while(num > 0):
        sol1 = num / 2

        check = sol1 - int(sol1)

        if(check > 0):
            array.append("1")
            num = sol1 - 0.5
        else:
            array.append("0")
            num = sol1
            
    #makes sure the binary value is a minimum of 4 bits long
    while(len(array) < 4):
        array.append("0")

    #reverses the array
    array = array[::-1]

    #joins the array into a string, return the string
    string = ''.join(array)

    return string
  
#binary(19) will return 10011
