python convert number into binary code example

Example 1: 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 2: 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
