Please check why my beginner's Calculator isn't working!

Question

#Project "basic Calculator" #-I am a beginner, so dont judge plz

import math

#FIRST ALGORITHM THAT DIDNT WORK
#-----------------------------------------------------------------------
#x = float(input("Give me a number: "))
#print("Your first number is ", x)

#y = float(input("Give me another number: "))
#print("Your second number is ", y)

#z = str(input("Addition, Subtraction, Multiplication or Division ?"))
#-----------------------------------------------------------------------

#I SAW THIS TRICK ON STACKOVERFLOW BUT IT DIDNT WORK
#-----------------------------------------------------------------------
x , y = float(input("Give me two numbers:")).split(",")
print("One number is ", x)
print("Second number is ", y)

z = str(input("Addition, Subtraction, Multiplication or Division ?"))
#-----------------------------------------------------------------------

#THE IF STATEMENTS
#-----------------------------------------------------------------------
if z == "Addition" or z == "addition":
print(x + y)
elif z == "Subtraction" or z == "subtraction":
print(x - y)
elif z == "Multiplication" or z == "multiplication":
print(x * y)
elif z == "Division" or z == "division":
print(x / y)
else:
print("Sorry we couldn't catch you, can you repeat?")
z = str(input("Addition, Subtraction, Multiplication or Division ?"))

Answer 1

This is because in the line
x, y = float(input("Give me two numbers:")).split (",")

.split() is a method for strings. float() converts the input to float and .split() cannot work on floats.

So what you could've done was
x, y = float(input("Give me two numbers:").split(","))
#the brackets have been changed.

What it would do is split the input by a comma and change it to a list. So the input
12,13
will become ["12", "13"]

But the problem is, it would still not work, because float() cannot have a list as arguement (that is, float (["12", "13"]) would give an error. So what you can do is first take the input separated by comma, and then convert each to a float. There are better ways (like map()), but this is good for a beginner. Like this

x, y = input("Give me two numbers:").split(",")
x = float(x)
y = float(y)
#the rest of the code

EDIT:
I didn't see that there are 2 ways in question. But as for me, the first way of taking input is working fine
