Variables for String

What is a variable? In simple words, a variable is a data store. It is very easy to create a variable in Python - you need to assign a value to a certain identifier using the "=" assignment operator. Let's look at the example of how to create a variable.

If you display this variable on the screen, you will get such an output: Rose

Now the variable flower refers to the next line "Rose". But if you want to change the value of this variable you can do it very easily. Look at the example.

You have changed the variable. And if you display the variable flower on the screen, you will get: Lily.

Note that we have assigned string values to variables. And when we work with strings, we have to enclose them in quotes, if you don't, you will get an error.

It's time to practice!
