What is wrong with this python code?
import turtle
turtle.pencolor("red")
turtle.bgcolor("black")
turtle.forward(100)
turtle.right(90)
turtle.forward (100)
turtle.right(90)
turtle.forward(100)
turtle.forward(90)
There is nothing technically wrong with the code, as it will execute without errors. However, the last line (`turtle.forward(90)`) may have been intended to turn the turtle to the left 90 degrees. Without the turn, the turtle will continue moving in the same direction as the previous forward command.
There doesn't seem to be anything inherently wrong with the code, but there is a redundancy in the `turtle.forward(90)` at the end. You can remove it since it duplicates the previous `turtle.forward(100)` command. Here's the corrected code:
```python
import turtle
turtle.pencolor("red")
turtle.bgcolor("black")
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
```
This code will draw a rectangle with red lines on a black background using the turtle module.
