Somewhat similar solution

def to_bin(dec):    flag = True    bin_str = ''    while flag:        remainder = dec % 2        quotient = dec / 2        if quotient == 0:            flag = False        bin_str += str(remainder)        dec = quotient    bin_str = bin_str[::-1] # reverse the string    return bin_str
