Python “Type Conversion”

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”) ?

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

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

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

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