Converting Decimal IP Address to Hexadecimal equivalent

ip = input("Enter the IP Address : ")
L1 = ip.split(".")
str1 = ""

for i in range(len(L1)):
    int_i = int(L1[i])
    hex_val = str(hex(int_i))
    str1 += hex_val[2:].upper()
    if i != len(L1) - 1:
        str1 += "."

print("The IP Address in Hexadecimal : ", str1)
