Python “Type Conversion”

Question

Can someone please answer the following in regards to these two conversion examples:
QC-1:
>>>float(“300” + int(input(“4”)))
I. How does python read this?
II. What is the order in which python calculates this
III. What’s the difference between:
Int(“2”) + (“3”) and Int(“2” + “3”) ?

Answer 1

float("300" + int(input("4")))
=>
step1. ask for input and show 4
step2. convert your input to int
step3. Error: "str" can't be added by "int"
int("2") + ("3")
=>
step1. convert str "2" to int 2
step2. Error: "int" can't be added by "str"
int("2" + "3")
=>
step1. "2" + "3" = "23"
step2. convert str "23" to int 23
step3. return int 23

Answer 2

davy hermans really? let me try it
i seldom use tuple so I'm not sure😆
***
ok, I've tried it, you're right👍

Answer 3

I agree with Flandre Scarlet but i think (correct me if i am wrong)
("3") would be a string
("3",) to make it a tuple

Answer 4

Bayshawn
in python, variables can't be added between different types, except for int and float, they'll become both float
therefore,
int("2") + int("3") is valid
int("2" + "3") is valid
int("2") + "3" is invalid

Answer 5

thanks guys I appreciate it! Flandre Scarlet and are we sure int(“2”) + int(“3) produces an error when both are the same?

Answer 6

Flandre Scarlet thank you 😊
