The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.
Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.
However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
user_str1 = str ( input ("Please enter a phrase: "))
user_str2 = str ( input("Please enter a second phrase: "))
def strcmp (word):
user_in1 = int (len(user_str1))
user_in2 = int (len(user_str2))
if user_in1 > user_in2:
return "Your first phrase is longer"
elif user_in1 < user_in2:
return "Your second phrase is longer"
else:
return "Your phrases are of equal length"
Three characteristics of an ideal encrytion scheme are:
1. The encryption sheme should be strong: the algorithm is imprevious to direct attack and attempts are derived.
2. The encryption scheme should create unique ciphertext from the same plaintext for each key permutation, among other traits.
3. It should take at least millions of years to break ideal encryption scheme, based on mathematical predictions.
