Answer: This chapter is about variables in Python. So a variable can be any data type. And to find the datatype of a variable we need to use below code: x =10 print (type (x)) This will output: integer Now we can covert a string into integer as below:x=input("Enter X:")But above x is considered as string, and we need to convert it to integer to make use in for loop or any calculation.we can use:int(x), and this will convert x to int from string.Also, we have operators to change the variable values like =. +=, -=, /=, *= etc. So you need to remember these, and you will be up with all that is required for understanding variables. And rest is self explanatory certainly.
