The thing that you will want to remember when you are working with these variables is that you have to assign a value in order to make the work happen in the code. These variables are also just going to be spots in your code that are going to reserve some memory for the values of your choice.

The Python Strings

The next topic that we need to take a look at in this chapter is going to be all about the strings. These strings are going to help us to learn more about how we can control some of the different parts of our codes, and will make it easier to understand what the string is. as a review, a string is just going to include a series of text characters that are found in our code for us to use.

Now, when you are working with these strings, you will find that there are some different types of operators that you are able to use when you bring them up. An operator is simply a symbol that is able to perform a specific operation that is inside of your code. When we are in this kind of situation, the operation is going to be performed on the strings. Some of the operators that you are going to be able to find here will include some of the following:

1. The concatenation operator: This is going to be the type of operator that you will use when it is time to take those strings and concatenate them.

2. Repetition operator: This is going to be the type of operator that you are able to use when you would like to get more than one copy of your string, and often many of these copies. You are able to use this one and then choose the number of times you would like to see the string repeat.

3. Slice operator: This is going to be an operator that will take a look through the chosen string, and then will figure out the specific character that you would like to work with from there. Any time that we bring this one up, you will need to remember that the first character of your string is going to be zero.

4. Range slice operator: This is another operator that we are able to use because it can retrieve a range of characters out of the index, rather than just one character to you. If you would just like to have it showcase out one part, or one word, of that string, then you would need to work with this operator.

5. In operator: This operator is going to spend some time searching for a specified character in your target string. If you do have that specific character found in the string, then you will get the True answer returned to you. But if the operator is not able to find that answer in the string, then the False answer is going to be returned to you.

6. No in operator: This is the operator that will work in the opposite manner as the in operator.
