I’ve learnt the concept of infix to postfix and now I can do by hand infix to postfix conversion. Now, I want to write code in Python for it.

First I need to know, how do I read values from left to right in Python?

Then, I need to know, how to check if the string is left paranthesis, operand, operator or right paranthesis in Python. Other than that, I can write it.
