The Thinking Effect

Programming Challenges

Your Thinking Challenge Problems

Problem 1:

Modify the thinking code so it uses a loop

Problem 2:

Modify the thinking code so it will print thinking from 1 to 10 dots after it

Problem 3:

Modify the thinking code so it will print thinking from 1 to 10 dots after it, but will run for a total of 3 times

Problem 4:

Modify the thinking code so it will run for 3 seconds.
Allow the user to tell you the message they want to display (not "thinking")

Just in case you wanted to review...

The print statement... What's end??

The end parameter in the Python print() function controls what is printed at the end of the output.
By default, print() appends a newline character (\n), so each print() call starts on a new line. 1
You can change this behavior by specifying a different value for end.

We also need something called flush

Why Use flush=True?

It's useful for real-time effects, like typing animations or progress bars, where you want each part of the output to appear instantly.

What is flush=True

Normally, the output of print() is buffered
- - This means Python waits to accumulate more data before actually displaying it in the terminal (especially in interactive programs).
flush=True forces Python to immediately display the output without waiting.

So... Where's the thinking

What do we need to accomplish with this effect?

We want to write a message
Change the message to include dots after it, which keep growing the longer it runs
Write everything on the same line (rewrite the line before it)

Here's a Basic way to implement that with print statements:

We print the message
Sleep to simulate thinking
Write the next message (which is longer) on the same line
- - using the end = "\r"
Keep repeating
