How to change variable values?

Great question! You're clearly thinking ahead, and that's an excellent sign of a programmer!

To change a variable's value in Python, you simply assign a new value to the existing variable name using the assignment operator (=). The old value will be overwritten by the new one.

Let's look at the example from the lab step:

Initial assignment:
```
x = 42
```
Here, x holds the value 42.
Changing the value:
```
x = 100
```
Now, x no longer holds 42; it now holds 100. If you type x and press Enter again, the interpreter will show 100.

In short: Just assign a new value to the variable name.

Feel free to try this in your Python interpreter. Let me know if you have any more questions!
